Clear Gloss Lacquer

defoamer (Neocryl AP-2650, Zeneca), pH adjuster (AMP 95), coalescents, and surfactant (Aerosol OT 75) are added and thoroughly mixed for 20 minutes. A wax dispersion, for improved mar resistance, and fungicide are then added. Final pH adjustment is with AMP 95, and viscosity with demineralised water.

A layer of transparent lacquer or PVC plastisol may be superimposed as desired to protect print and to control the gloss of the finish. A vinyl-acrylic lacquer may be applied in tandem with colour printing or, say, a clear plastisol coating by screen printing, usually in the last stage as the material passes to the oven for fusion and expansion. 

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.

A very low viscosity clear lacquer containing a UV absorber to protect FRP components from the effects of weathering. Can also be employed to restore gloss and lustre to already weathered components. 

Paints or surface coatings are complex multiphase colloidal systems that are appUed as a continuous layer to a surface [1], A paint usually contains pigmented materials to distinguish it from clear hlms that are described as lacquers or varnishes. The main purpose of a paint or surface coating is to provide aesthetic appeal as well as to protect the surface. For example, a motor car paint can enhance the appearance of the car body by providing color and gloss and it also protects the car body from corrosion.
