can be understood by "painting" as a product fluid, applied on a relatively thin surface layer is transformed over time into a solid film which adheres to the surface, so that coats, protects and decorate the item that has been applied.
pigments are powdered, insoluble by themselves in the liquid medium of painting, its functions are to provide color and hiding power, contribute to product
anticorrosive properties and give stability to different environmental conditions and chemical agents. Among the pigments used in paint manufacture various compounds are based on chromium and lead, zinc powder, titanium dioxide, barium sulfate, carbon black, aluminum powder and iron oxide
, as examples.
Within the formulation of the paintings are also called "loads", which meet the objective of extending the pigment and contribute to a fill effect. Among these materials are mineral substances such as barytes, chalk, kaolin, silica, mica, talc, etc., and synthetic origin such as chalk, kaolin treated and precipitated barium sulfate.
binders are generally organic substances whose main function is to provide protection, can be used in solid form, dissolved or dispersed in volatile organic solvents, in aqueous or emulsified in water. These substances include drying oils, natural resins and synthetic resins. Between drying oils, the most widely used is linseed oil.
natural resins are mostly of plant origin, except of shellac, now, its use has declined considerably due to the development of a large number of synthetic resins.
latter are typically used in combination with the aforementioned oils being more resistant to water and chemicals. Among the most widely used synthetic resins include alkyd resins, acrylic, phenolic, vinyl, epoxy, chlorinated rubber, polyurethane and silicone. Of these, the first is the most common.
solvents or vehicles are volatile liquid substances that give the paintings the fluid state necessary for its implementation, evaporating after application of the paint. The variety of solvents which occupies this industry is very broad but, nevertheless, its use has been declining in recent years because of environmental restrictions and cost, especially in the case of chlorinated solvents. Additives
under : These are substances in small doses added to fulfill specific functions that do not meet the main ingredients. Among the most used are drying materials, plasticizers and antisedimentables
types of paints most common are:
Special uses special paints paintings originate
An application of the paint manufacturing process is in the realization of Pain Bool
