Processing Guidelines

The recommended starting level of product is 0.25% of the total weight of the system. In paint manufacture, best results are usually obtained when half of the antifoam is added to the pigment before grinding to suppress the formation of foam, and the remainder added to the “let down” portion. In adhesives, a starting addition of 0.5-2.0% of the weight of the latex solids is generally recommended.
