Chemicals for Paints
Chemicals for Paints | Paint is the name normally given to a family of products (liquid, viscous or powdered solids) that, after application in a thin layer form, to a substrate, becomes an opaque solid film. Paints are used to protect and color objects or surfaces.
Paint is very common and can be applied to almost any type of object. It is used in art and industry: metal structures, automobile production, equipment, piping, electrical and electronic products; as anti-corrosion protection in civil construction: on interior and exterior surfaces exposed to weather conditions; a large number of current and future applications, such as flasks used for perfumes and makeup.
Paints and Varnishes | Varnish, is a viscous mixture of natural substances, combined with the purpose of obtaining a protective film from moisture, weather or even artistic finish. Raw material is obtained, usually, from vegetables and their sap, other substances are then added for (its) shine, hardness, drying, malleability for later use and commercialization. The resins are then diluted and mixed with solvents such as thinner, alcohol, turpentine, among others. Some varnishes contain added pigments to change the natural color and obtain a specific effect. There are resin varnishes or of petroleum derivatives, nitrocellulose, polyurethane (PU), marine and polyester, are types of varnishes designations, well known in the market and used as nail polish, in automotive and furniture industries, in musical instruments, etc. This viscous mixture is applied with brush, doll procedure, spray or air compressor and gun.
Pending the manufacturer’s product specifications and the coating process, the protection film is achieved by the thinner evaporation or by chemical drying, consequence of the catalyst agent action.
