High gloss paints

It was also shown that stable latexes of high solid content, and small particle size could be practically obtained by this emulsion polymerization technique. Such microlatexes based on acrylic polymers modified by polyesters are an interesting approach to waterborne coatings leading to high gloss paint films (9).

Blushing . (1) Film defect, which appears as a milky opalescence as the film dries can be a temporary or permanent condition. It is generally caused by rapid evaporation, moisture, or incompatibility. Syn fog. (2) Milky opalescence which sometimes develops as a film of lacquer dries, and is due to the deposition of moisture from the air and/or precipitation of one or more of the solid constituents of the lacquer usually confined to lacquers which dry solely by evaporation of solvent. Also applies to printing inks. (3) A white or grayish cast on high gloss paint results from the precipitation of binder solids owing to incompatibility with water, oil, or solvent. 

Compatibility of the soluble resinous thickener with the main binder needs to be checked and excessive amounts of particulate thickeners can reduce gloss, especially in high gloss paints. Large differences in refractive index between binder and particulate thickeners can cause loss of clarity in clear coatings and should be avoided. 

Air pollution eind political reaction, first in the Los Angeles basin then in the Sein Freincisco Bay area, started a series of regulations not only on automobile and factory exhausts, but also on most kinds of solvent-based paints. Quickly the technologies of latex paint and occasional, water reducible alkyds from the 1940 s were tried for all meumer of paint applications, both trade sales and industrial. While both kinds were successful then, for interior flat wall paints, neither served well in exterior, high gloss paints and their success in these, more difficult uses only now is emerging in the 1970 s. 

Figure 9.7 Volume ratio of raw materials of a typical flat and high-gloss paint.

Paints above CPVC are flat and are used predominately for interior coatings. Figure 9.7 shows the volume ratio of the raw materials for different types of coatings, a flat interior paint and high-gloss paint.
