Definition of Foam and Defoamer

Foam can be defined as dispersing of gas in liquid. It can be generated during production of coating (grinding, mixing and filling), during application (brushing, rolling and low pressure spraying), or when application of coat in porous substrate like wood surface. To solve this problem, the producer of coating can use defoamers as an additive.
