Paint types Wood coatings

Poly(vinyl ester) dispersions are important binders for indoor (conventional, solvent-free) and outdoor paints, special coatings, and textured finishes. Special types are used for wood paints and for coating paper and cardboard. Poly(vinyl ester) dispersions are also important in the adhesives and textile finishing industries. 

In the U.S., the most common construction material in terms of exposed surface area is comprised of various types of painted surfaces, especially painted wood, which is found to some extent on most residential buildings. The sensitivity of paints depends on their constituents research has shown that acid-soluble components such as CaC03 or ZnO may be selectively leached out from the coating (33). To our knowledge, the effects of such leaching on coating service lives have not yet been quantified. 

Two basic types of finishes (or treatments) are used to protect wood surfaces during outdoor weathering those that form a film, layer, or coating on the wood surface, and those that penetrate the wood surface to leave no distinct layer or coating. Film-forming materials include paints of all description, varnishes, lacquers, and also overlays bonded to the wood surface. Penetrating finishes include preservatives, water repellents, pigmented semitransparent stains, and chemical treatments. 

The coating durability of organolead-treated southern pine in exterior exposure was reported (144), Significant improvement in the durability of a vinyl-acrylic latex and an alkyd paint on treated wood was demonstrated. Improved durability appeared to be independent of the type or concentration of the organolead-treated compounds. 

Vinyl acetate monomer (VAM) is an important chemical intermediate used in the production of several types of paints, adhesives as wallpaper paste and wood glue, and surface coatings such as the protective laminate films in automotive safety glass [2,104,237,238]. 

Primer prl-m9r (1819) n. First complete coat of paint of a painting system apphed to a surface. Such paints are designed to provide adequate adhesion to new surfaces and are formulated to meet the special requirements of the surfaces. The type of primer varies with the surface, it condition, and the total painting system to be used. Thus, primers for new wood and certain other surfaces must provide for exceptional absorption of the medium. Primers for steelwork contain special anti-corrosive pigments, such as red lead, zinc chromate, zinc powder, etc. A coating applied to a surface, prior to the application of an adhesive, to improve the performance of...
