Silicone-containing defoamer for aqueous systems with low to high layer thickness for removing application-related microfoam.


Coatings Industry

BYK-1785 is highly effective in aqueous systems of low to high layer thickness which are applied by means of an airless or airmix method. It is also suited to coatings which are rolled or painted. It is extremely good at removing microfoam from the coating and influences neither the transparency or gloss in high-gloss systems. BYK-1785 can be used in pigmented systems and in clear coatings. The additive is APEO free.
