What is antifoam additive?
It can reduce the surface tension of water, solution and suspension liquid. It can prevent the formation of foam and reduce or eliminate the existing foam. The addition of antifoam additives into the lubricants can prevent the foam caused by the air from affecting the normal operation of the lubricating system. The commonly used antifoam additives include: dimethyl silicone oil, derivatives from alkylated succinic acid, polyhydric aliphatic alcohol and ester from long chain aliphatic acid.
