A paint thinner is a solvent used to thin oil-based paints or clean up after their use. Commercially, solvents labeled "Paint Thinner" are usually mineral spirits having a flash point at about 40 °C (104 °F), the same as some popular brands of charcoal starter.
Common solvents used as paint thinners include:
Less common solvents used as paint thinner include:
Exposure to vapors created by paint containing thinner or its clean up may be hazardous. The American Conference of Governmental Industrial Hygienists has established threshold limit values (TLVs) for most of these compounds. TLV is defined as the maximum concentration in air which can be breathed by a normal person (i.e., excluding children, pregnant women, etc.) in the course of 40 hours work (in US work conditions) per week, day after day through their work life without long-term ill effects. In underdeveloped countries workers commonly experience much higher exposure to these chemicals with consequent damage to their health.
Acetone, or propanone, is the organic compound with the formula (CH3)2CO. It is a colorless, volatile, flammable liquid and is the simplest and smallest ketone.
Acetone is miscible with water and serves as an important solvent in its own right, typically for cleaning purposes in laboratories. About 6.7 million tonnes were produced worldwide in 2010, mainly for use as a solvent and production of methyl methacrylate and bisphenol A. It is a common building block in organic chemistry. Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner. It has VOC exempt status in the USA.
Acetone is produced and disposed of in the human body through normal metabolic processes. It is normally present in blood and urine. People with diabetes produce it in larger amounts. Reproductive toxicity tests show that it has low potential to cause reproductive problems. Ketogenic diets that increase ketones (acetone, β-hydroxybutyric acid and acetoacetic acid) in the blood are used to counter epileptic attacks in infants and children who suffer from recalcitrant refractory epilepsy.Boga (noisemaker)
The boga or PVC cannon is a noisemaker popular during New Year celebrations in the Philippines. Use of the device has been banned by the Philippine government since 2006.Originating from the province of Cavite, the device is made from a length of pipe of substantial diameter mated to a toy gun. Denatured alcohol (sometimes paint thinner or acetone) is squirted or sprayed into the pipe's breech end and ignited by the toy gun's trigger mechanism which is connected to a piezo igniter or by putting small fire. The combination of air and flammable fuel in the pipe's enclosed space when ignited by a spark from the trigger mechanism or by small fire causes the fuel-air mixture to combust, resulting in a loud, booming sound.
The first prototype is made from segmented tin cans connected with packaging tapes or electrical tapes and cut PET bottles (which is still used) and later design is made of PVC pipes. Other modifications of boga are introduced such as firing round projectiles which can be used as a weapon and pet bottles as breech end.Council of the European Union decisions on designer drugs
Council of the European Union decisions on designer drugs. Council of the European Union issued a set of decisions on 7 designer drugs to make them subject to control measures and criminal provisions.Desomorphine
Desomorphine is a synthetic opioid developed by Roche, with powerful, fast-acting effects, such as sedation and analgesia. It was first discovered and patented by a German team working for Knoll in 1922 but wasn't generally recognized. It was later synthesized in 1932 by Lyndon Frederick Small, who also successfully patented it in 1934 in the United States, desomorphine was used in Switzerland under the brand name Permonid and was described as having a fast onset and a short duration of action, with relatively little nausea compared to equivalent doses of morphine. Dose-by-dose it is eight to ten times more potent than morphine.Desomorphine is a morphine analogue where the 6-hydroxyl group and the 7,8 double bond have been reduced. The traditional synthesis of desomorphine starts from α-chlorocodide, which is itself obtained by treating thionyl chloride with codeine or prescription opioid pain medicines such as OxyContin and Vicodin. By catalytic reduction, α-chlorocodide gives dihydrodesoxycodeine, which yields desomorphine on demethylation.Diluent
A diluent (also referred to as a filler, dilutant or thinner) is a diluting agent. Certain fluids are too viscous to be pumped easily or too dense to flow from one particular point to the other. This can be problematic, because it might not be economically feasible to transport such fluids in this state. To ease this restricted movement, diluents are added. This decreases the viscosity of the fluids, thereby also decreasing the pumping/transportation costs.
One industrial application is the transport of crude oil via pipelines. Heavy crude oil/bitumen are fluids with high viscosity, especially at low temperatures. The addition of a diluent enables the diluted fluid (dilbit in the case of bitumen) to meet pipeline specifications in order for it to be efficiently transported. Typical diluent in this case is naphtha or condensate.
Types of diluents more familiar to the general public include paint thinner and nail polish thinner, both of which improve the consistency and applicability of the products to which they are added. Diluent is also used as a term in solvent extraction for an inert solvent in which a metal extraction agent (extractant) is dissolved. In solvent extraction the diluent has potentially several uses. It can be used as a solvent (in the purely chemical sense rather than the solvent extraction sense) to dissolve an extractant which is a solid and so render it suitable for use in a liquid–liquid extraction process. In other cases such as PUREX nuclear reprocessing the diluent (kerosene) is used to reduce the maximum metal loading which the organic layer can reach. If the organic layer was to acquire too much metal then a solid metal complex might form, or more worryingly in a nuclear process the potential for a criticality accident if the fissile metal concentration in the organic phase becomes too high.Drug harmfulness
Drug harmfulness is the degree to which a psychoactive drug is harmful to a user and is measured in various ways, such as by addictiveness and the potential for physical harm. More harmful drugs are called "hard drugs", and less harmful drugs are called "soft drugs". The term "soft drug" is considered controversial by its critics as it may imply that soft drugs cause no or insignificant harm.Endicott Island
Endicott Island is a 45-acre (18 ha) artificial island located in the U.S. state of Alaska, 2.5 miles (4 km) offshore and 15 miles (24 km) from Prudhoe Bay of the Beaufort Sea. Endicott Island was built in 1987 by Alaska Interstate Construction and is used by BP and Hilcorp Alaska for petroleum production.
Endicott Island has a permanent causeway connecting it to the mainland, unlike Northstar Island which is too far out for any kind of causeway to be built.
Endicott Island was the first continuously producing offshore oil field in the Arctic, producing around 20,000 barrels (3,200 m3) of oil per day. Approximately 423 million barrels (67,300,000 m3) had been produced as of March 2003. Processed oil is sent from Endicott Island through a 24-mile (39 km) pipeline to the Trans-Alaska Pipeline, and thence to Valdez, Alaska.In 1998 and 1999, illegal waste dumping at Endicott Island resulted in combined fines of US$1,500,000 against BP and Doyon Drilling, with further settlements of $24,000,000. In September 1999, one of BP’s US subsidiaries, BP Exploration Alaska (BPXA), agreed to resolve charges related to the illegal dumping of hazardous wastes on the Alaska North Slope, for $22 million. The settlement included the maximum $500,000 criminal fine, $6.5 million in civil penalties, and BP’s establishment of a $15 million environmental management system at all of BP facilities in the US and Gulf of Mexico that are engaged in oil exploration, drilling or production.
The charges stemmed from the 1993 to 1995 dumping of hazardous wastes on Endicott Island by BP’s contractor Doyon Drilling. The firm illegally discharged waste oil, paint thinner and other toxic and hazardous substances by injecting them down the outer rim, or annuli, of the oil wells. BPXA failed to report the illegal injections when it learned of the conduct, in violation of the Comprehensive Environmental Response, Compensation and Liability Act.Epic Mickey
Epic Mickey is a platform game developed by Junction Point Studios and published by Disney Interactive Studios for the Wii console. The game focuses on Mickey Mouse, who accidentally damages a world created by Yen Sid for forgotten characters and concepts, and is forced to fix the world while combating antagonists with a magic paintbrush. Epic Mickey notably features the first appearance of one of Walt Disney's first successful cartoon characters, Oswald the Lucky Rabbit, as a major character since 1943. The game also marks the first time that Oswald and Mickey appeared together.
Epic Mickey was part of an effort by Disney to re-brand the Mickey Mouse character by placing less emphasis on his pleasant, cheerful side and reintroducing the more mischievous and adventurous sides of his personality, focusing on the idea of depicting him as an epic hero. It was directed by Warren Spector, who collaborated with both Walt Disney Animation Studios and Pixar in conjunction with the project. The game was announced in 2009, and released in November 2010. While the game received average reviews from critics, it has garnered a following in later years. It has successors to the franchise such as Epic Mickey 2: The Power of Two and Epic Mickey: Power of Illusion.Icky-pick
Icky-pick or icky-pic is a name for a gelatinous substance or filler contained within outdoor-rated communications cables, including both twisted pair copper cabling and fiber optic cabling.
PIC is the abbreviation for Plastic Insulated Cable. The cable is filled with an icky substance. The filled cable itself, therefore, is called an "Icky PIC".
Icky-pick has two primary functions:
Deter animals from biting and damaging the cable due to the smell and taste of the gel
Seal any nick or gash in the outer jacket if they do bite it, preventing water from entering the cable and damaging it by corrosion and freeze expansionThe actual icky-pick compound is a very thick petroleum-based substance with very high flammability, and consequently is only rated for outdoor use, frequently direct-buried in the ground. An outdoor cable spliced onto an indoor terminal block is prone to leak the gelatin which is a fire hazard, hence in many situations the icky-pic cable is spliced (usually outside the building) to a short run of normal cable which is run in a protective conduit into the building and then terminated. The thick gelatin stains clothing and hands and is very difficult to remove.
When fiber-optic cables are to be spliced, the gelatin must be removed with solvents and swabs to prevent fouling of the splice. Paint thinner or charcoal starter is a frequently used and commonly available remover and clean-up agent.Lacquer thinner
Lacquer thinner is usually a mixture of solvents able to dissolve a number of different resins or plastics used in modern lacquer.Previously, lacquer thinners frequently contained alkyl esters like butyl or amyl acetate, ketones like acetone or methyl ethyl ketone, aromatic hydrocarbons like toluene, ethers such as glycol cellosolves, and/or alcohols.Modern lacquer thinners increasingly have to comply with low-VOC regulations. These formulations are often mostly acetone with small quantities of aromatic solvent.MV S Venus
The MV S Venus is a freighter of Panamanian registry, attacked by Somali pirates on January 1, 2009. It was successfully defended by defensive actions by members of Anti Piracy Maritime Security Solutions who used paint thinner, Molotov cocktails and a flare gun to set the attacking vessel ablaze.
After receiving a distress call from the freighter, French naval frigate F792 Premier-Maître L’Her headed for the rescue. However, before her arrival, the pirates ceased their attack. After that, MV S. Venus reiterated its distress call because of another attack at about 40 kilometers from the position, and the frigate once again went to the rescue of the Panamanian cargo ship and found two small boats nearby,
designated by the crew of the ship as the skiffs for assault pirates. The special force of the French navy ordered two skiffs carrying eight Somalis to stop. A visit on board the boat found six AK-47 assault rifles, one RPG (Rocket Propelled Grenade) rocket-launcher, ammunition, a grappling hook and two boarding ladders, and a GPS (Global Position System) among others, which were confiscated by the navy. The eight Somalis suspected of piracy were taken into custody by the French frigate to be handed over to the authorities in that country.Oil painting
Oil painting is the process of painting with pigments with a medium of drying oil as the binder. Commonly used drying oils include linseed oil, poppy seed oil, walnut oil, and safflower oil. The choice of oil imparts a range of properties to the oil paint, such as the amount of yellowing or drying time. Certain differences, depending on the oil, are also visible in the sheen of the paints. An artist might use several different oils in the same painting depending on specific pigments and effects desired. The paints themselves also develop a particular consistency depending on the medium. The oil may be boiled with a resin, such as pine resin or frankincense, to create a varnish prized for its body and gloss.
Although oil paint was first used for Buddhist paintings by painters in western Afghanistan sometime between the fifth and tenth centuries, it did not gain popularity until the 15th century. Its practice may have migrated westward during the Middle Ages. Oil paint eventually became the principal medium used for creating artworks as its advantages became widely known. The transition began with Early Netherlandish painting in Northern Europe, and by the height of the Renaissance oil painting techniques had almost completely replaced the use of tempera paints in the majority of Europe.
In recent years, water miscible oil paint has become available. Water-soluble paints are either engineered or an emulsifier has been added that allows them to be thinned with water rather than paint thinner, and allows, when sufficiently diluted, very fast drying times (1–3 days) when compared with traditional oils (1–3 weeks).Oxford Circus fire
The Oxford Circus fire occurred on Friday 23 November 1984 at 9.50pm at Oxford Circus station on
the London Underground. Oxford Circus station is in the heart of London's shopping district and is served by three deep-level tube lines: the Bakerloo line, Central line and Victoria line. The three lines are linked by a complex network of tunnels and cross-passages which all converge to a common booking hall situated beneath the junction of Oxford Street and Regent Street.
The fire started in a materials store at the south end of the northbound Victoria line platform, which was being used by contractors working on the modernisation of the station. It gutted the northbound Victoria line platform tunnel and the passages leading off it. The adjacent northbound Bakerloo line platform suffered smoke damage, as did the escalator tunnel and the booking hall. Other areas of the station were undamaged. The most likely cause of the fire was a smoker discarding smoking materials through a ventilation grille into the materials store, which ignited rags or paint thinner.The Pothole
"The Pothole" is the 150th episode of the sitcom Seinfeld. This was the 16th episode for the eighth season. It aired on February 20, 1997. This episode earned Andy Ackerman an Emmy Award for Outstanding Direction. Jerry Seinfeld, in an appearance on The Tonight Show the night before the episode aired, declared "The Pothole" to be one of the best episodes of the series.The Secret Code (Seinfeld)
"The Secret Code" is the 117th episode of NBC sitcom Seinfeld. This was the seventh episode of the seventh season. It aired on November 9, 1995.Thinner
Thinner may mean:
Paint thinner, a solvent used in painting and decorating, for thinning oil-based paint and cleaning brushes.
Thinner (novel), a 1984 horror novel by Stephen King, written as Richard Bachman
Thinner (film), a 1996 horror film based on the novel by Stephen King
Thinner (netlabel), a German netlabel releasing electronic musicToluene
Toluene (), also known as toluol (), is an aromatic hydrocarbon. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a CH3 group attached to a phenyl group. As such, its IUPAC systematic name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.
As the solvent in some types of paint thinner, contact cement and model airplane glue, toluene is sometimes used as a recreational inhalant and has the potential of causing severe neurological harm.Varnish
Varnish is a clear transparent hard protective finish or film. Varnish has little or no color and has no added pigment as opposed to paint or wood stain which contains pigment. However, some varnish products are marketed as a combined stain and varnish. Varnish is primarily used in wood finishing applications where the natural tones and grains in the wood are intended to be visible. It is applied over wood stains as a final step to achieve a film for gloss and protection. Varnish finishes are usually glossy but may be designed to produce satin or semi-gloss sheens by the addition of "flatting" agents.
The term "varnish" refers to the finished appearance of the product. It is not a term for any single or specific chemical composition or formula. There are many different compositions that achieve a varnish effect when applied. A distinction between spirit-drying (and generally removable) "lacquers" and chemical-cure "varnishes" (generally thermosets containing "drying" oils) is common, but varnish is a broad term historically and the distinction is not strict.White spirit
White spirit (UK) or mineral spirits (US, Canada), also known as mineral turpentine (AU/NZ), turpentine substitute, petroleum spirits, solvent naphtha (petroleum), Varsol, Stoddard solvent, or, generically, "paint thinner", is a petroleum-derived clear liquid used as a common organic solvent in painting.A mixture of aliphatic, open-chain or alicyclic C7 to C12 hydrocarbons, white spirit is insoluble in water and is used as an extraction solvent, as a cleaning solvent, as a degreasing solvent and as a solvent in aerosols, paints, wood preservatives, lacquers, varnishes, and asphalt products. In western Europe about 60% of the total white spirit consumption is used in paints, lacquers and varnishes. White spirit is the most widely used solvent in the paint industry. In households, white spirit is commonly used to clean paint brushes after use, to clean auto parts and tools, as a starter fluid for charcoal grills, to remove adhesive residue from non-porous surfaces, and many other common tasks.
The word "mineral" in "mineral spirits" or "mineral turpentine" is meant to distinguish it from distilled spirits (distilled directly from fermented grains and fruit) or from true turpentine (distilled tree resin).
