SY-4216 Coating defoamer
1.product description
SY-4216 is a type of water-based emulsion defoamer which composed by long-chain aliphatic alcohols and their acid derivatives. It inhibits the formation of foam within the latex of styrene-butadiene, pure acrylic, styrene-acrylic, ethylene polyvinyl acetate; It can also control the foam caused by water-based systems such as poly vinyl alcohol or adhesives. With the advantages of small dosage, long lasting and good compatibility, it is suitable for coatings, latexes, adhesives and other water-based systems.
