Recent advances in coalescing solvents for waterborne coatings

2 RECENT ADVANCES IN COALESCING SOLVENTS FOR WATERBORNE COATINGS [Pg.969]

The role of eoaleseing solvents in coating formulations, the factors which affect the choice of eoaleseing solvents, and the recent developments in esters of low volatility, low odor and rapid biodegradability for use in coating formulations are discussed. [Pg.969]

The term paint is widely used to describe a coating applied to a variety of substrates for proteetive or decorative purposes. Paint also implies a pigmented species, whereas surfaee eoatings is a broader term for coating systems with or without pigments used for any eoating purpose. [Pg.969]

All paint systems may be considered as a combination of a small number of constituents. These are eontinuous phase or vehicle (polymer and diluent), discontinuous phase or pigment and extender, and additives. [Pg.969]

This paper is not concerned with the detail of paint formulation, but the polymer types most widely eneountered are aUcyds, polyurethanes and nitrocellulose in solvent based systems, and acrylics, styrene-acrylics, and copolymers of vinyl acetate in water-based coatings. [Pg.969]
