Vinyl lacquers are used mainly where a high degree of chemical resistance is required these lacquers are based on vinyl chlorides and vinyl acetates. Acrylic lacquers are based on methyl methacrylate and methyl acrylate polymers and copolymers. Other esters of acrylic and methacrylic acid also may be used to make nonconvertible film formers. Judicious selection of these acrylic acid or methacrylic acid esters allows one to produce film formers with specifically designed properties such as hardness, flexibility, gloss, durability, heat, and chemical resistance. Acrylic lacquers, however, are not noted for their water resistance. The principal uses of acrylic-type lacquers are fluorescent and metallic paints, car refinish applications, clear lacquers and sealers for metals, and protective coatings for aircraft components and for vacuum-deposited metals, as well as uses in pigmented coatings for cabinets and appliances. 

Product finishes are coatings formulated specifically for original equipment manufacture (OEM) to satisfy application conditions and manufacturing requirements for a wide variety of industrial and consumer products, e.g., wood and metal furniture and fixtures automotive and nonautomotive transportation, aircraft, machinery and equipment, appliances, electrical insulation, film, paper, foil, toys, and sports goods. 

In nonweb applications the coating is applied to a specific part at the end of the fabrication process. The part is usually three-dimensional and of varying shape. Automobiles, appliances, and steel structures all have the coating applied to the individual items as they are being built. It should be noted that many smaller steel items are made from prepainted sheet steel. 

Unsaturated polyester is one of the most versatile thermosets in that it is used in the fabrication of a broad range of products, including structural parts of automobiles, building materials, coating materials, electrical parts, appliances, and boat hulls. Consequently, a variety of resin formulations have been developed, depending on specific applications as well as fabrication processes. Unsaturated polyester and...
