BYK-066N  
BYK-066N is a silicone defoamer for solvent-borne coating systems, which can prevent the formation of foam during the production of coatings and fillers. BYK-066N is effective in defoaming even with very small amounts of incompatible substances.
Suitable binders are: chlorinated rubber, epoxies, two-component polyurethane systems, alkyds/melamines, alkyds and self-crosslinking acrylates.
