High performance defoamer and deaerator BRB Siloen DA 291 for waterborne coatings
21 June 2023

BRB Siloen® DA 291 is a solvent-free highly effective defoamer and deaerator compound based on polyether siloxane technology and hydrophobic solids.

BRB Siloen® DA 291 is particularly suitable against micro-foams in waterborne formulation, partially in radiation curable formulation. It is also suitable for wood coating, industrial coating, printing inks as well as protective coatings.

BRB Siloen® DA 291 is designed to be used specifically in the grind stage; because of its highly incompatibility, it needs to be incorporated under high shear force to ensure a good distribution.
