Lacquers polyvinyl chloride

Two-piece food cans may be made by a draw-redraw process, in which lacquer is first applied to and cured on sheet. Blanks are then cut from the sheet and the can is drawn from the blank in two or three stages. The lacquer deforms with the drawing process and lubricates the draw. It then becomes the interior protective coating. Although epoxy-phenolic solvent-borne lacquers are used, even better drawing properties are obtained from organosols. These are dispersions of colloidal polyvinyl chloride powder in solutions of other mixed resins in solvent, e.g. chosen from epoxy, polyester, vinyl and phenolic.

Phosphites. The phosphates, second only to phthalates in production volume, are favored for flame resistance and low volatility. Tricresyl phosphate (mixed meta and para isomers) is the most popular it is used in polyvinyl chloride and in nitrocellulose lacquers. Resins plasticized with tricresyl phosphate are deficient in low-temperature flexibility. Diphenyl cresyl phosphate and triphenyl phosphate are other examples, the former for polyvinyl chloride, the latter for cellulose acetate. Diphenyl-2-ethylhexylphosphate is preferred to tricresyl phosphate in polyvinyl chloride where its low toxicity and improved low-temperature flexibility are required. Tn(2-elliylliexyl)-phosphale is outstanding among phosphates used in polyvinyl chloride with respect to low-temperature flexibility in flame- and oil resistance, however, it is inferior to tricresyl phosphate. Tri(butoxvethyl)phosphate finds some use in synthetic rubber.

Sodium ion-selective field-effect transistors (Na+ ISFETs) were prepared by using three different types of polymeric matrix materials, such as polyvinyl chloride, bio-compatible polymer (polyurethane) and Urushi (natural oriental lacquer). Their electrochemical characteristics were discussed in connection with their characteristics of polymeric matrix membranes.

Tetrahydrofuran is a solvent used in natural and synthetic polymers and resins such as polyvinyl chloride and vinylidene chloride copolymers. It is also used in the manufacture of lacquers, glues, paints, and inks. 

Di- -butyl phthalate is an odorless and colorless or faintly yellow oily liquid that does not occur in nature. It is a chemical that is added to hard plastics to make them soft. The plastics that di- -butyl phthalate is used most in are called polyvinyl chloride plastics and nitrocellulose lacquers. These plastics are used to make many products that we use every day such as carpets, paints, glue, insect repellents, hair spray, nail polish, and rocket fuel. In 1994, more than 17 million pounds (i.e., 7.8 million kilograms) of di- -butyl phthalate were made. 

The suspicion surrounding epoxy-phenolic and polyvinyl chloride lacquers of metal packaging, as well as the weight and energetic cost of recychng glass, favors plastic materials. They are used for applications including sterihzed food.

Polyvinyl chloride. Polyvinyl chloride (PVC) coatings, commonly called vinyls, are noted for their toughness, chemical resistance, and durability. They are available as solutions, dispersions, and lattices. Properties of vinyl coatings are listed in Table 10.15. They are applied as lacquers, plastisols, organisols, and lattices. PVC coating powders have essentially the same properties as liquids. PVC organ-isol, plastisol, and powder coatings have limited adhesion and... 

Polyvinyl chloride polymers This principal corrosion-resistant lacquer is made from polyvinyl chloride copolymers. The vinyl molecule is relatively large and will effectively dissolve in solvent in the 20 percent range. 

Eversorb 73 is a benzotriazole type absorber. It offers superior light protection of polyolefin substrates against the deterioration of UV radiation. Eversorb 73 is also efficient for the light stabilization of polyvinyl chloride, unsaturated polyester, polyurethane, styrenic polymers, coatings and lacquers. 

Butoxyethanol acetate in the environment also comes from some industrial activities. It is prepared by reacting 2-butoxyethanol with acetic acid, acetic acid anhydride, or acetic acid chloride. 2-Butoxyethanol acetate is widely used as a slow-evaporating solvent for lacquers, varnishes, epoxy resins, and enamels. It is also used in polyvinyl acetate latex, and it may be used in some ink and spot remover formulations. 

Di(2-ethylhexyl) isophthalate (dioctyl iso-phthalate, DIOP) n. A primary plasticizer for PVC, most notable for low volatility and its resistance to marring by nitrocellulose lacquers, in addition to good general-purpose properties. It is also compatible with polyvinyl butyral, vinyl chloride-acetate copolymers, cellulosic resins, polystyrene, and chlorinated rubber. 

Polyvinyl Acetate n A colorless, odorless, nontoxic, transparent, thermoplastic, water-insoluble, resinous high polymer derived from the polymerization of vinyl acetate with a catalyst used as a latex binder in certain paints and as an intermediate in the synthesis of polyvinyl acetal and polyvinyl alcohol. The major use is in water-based latex paints, adhesives, fabric finishes, and lacquers. In the plastics industry, the copolymers of vinyl acetate, particularly with vinyl chloride, are of most interest. Abbreviation for PVA and PVAc.
