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


Coatings Industry

BYK-1780 is highly effective in aqueous systems, in particular in thick layer systems which are applied by means of an airless or airmix method. It is extremely good at removing microfoam from the coating and influences neither the transparency or gloss in high-gloss systems. BYK-1780 can be used in pigmented systems and in clear coatings. The additive is solvent-free.

Printing Inks

BYK-1780 is particularly suited to aqueous printing inks, overprint varnishes and aqueous, radiation curable printing systems.
