Abstract
This chapter presents a discussion of organic coating defects that occur on application or during drying and baking. The greatest emphasis is on cratering and its mechanisms, but a number of other defects, including dewetting, telegraphing, soak-in, pinholes, sagging, orange peel, flooding and floating, Bénard cells, wrinkling, popping, gassing, and air entrapment are described and discussed along with their mechanisms. Suggestions for reduction or prevention of many of the defects are included and relevant references are listed. Much of the discussion is based on long experience with automotive coatings, but the information is relevant to other industrial coatings, and many of the same defects also occur with architectural and maintenance coatings.
