Coatings Update: Pollution, toxicity, regulation and the paint industry: Part 2

Abstract

An interesting article in the American Paint & Coatings Journal [February 18 (1980) p. 55] describes for the consumer how his choice of paints will change because of the desire of the California Air Resources Board to decrease the air polluting aspects of these products. The article points out that the consumer will either use more waterborne paints or he will use oil‐based paints with higher solids. One of the immediate observations the consumer will make about higher solids paints is that they cost more. This is to be expected, of course, since the vehicle is generally more expensive than the solvent. On the other hand, the consumer is cautioned not necessarily to expect better performance associated with higher price. For sure, it will probably cover more surface but, in fact, it may dry more slowly and be less durable, and the fact that it is thick will adversely affect smooth flow and tend to inhibit the disappearance of brush marks. Furthermore, the high‐solids paints will tend to have a hard, glassy, smooth finish which is difficult to reproduce in low‐solids paints. Also, the low solvent paints will not cover greasy and chalky surfaces as well nor will they adhere as well. Thus, surface preparation becomes very important. This is indeed an interesting article, for all too often the role of the consumer is neglected in the mad scramble for compliance.
