BYK 1679

BYK 1679 is a very easy to incorporate defoamer for aqueous adhesive systems. The additive is extremely well suited to being incorporated without high shear forces in very low viscosity systems. It is particularly suitable for defoaming primary PE emulsions (eg Hordamer types). BYK 1679 is a suitable defoamer for use in the cooling water circuit when performing the underwater granulation of hot melt adhesives where Hordamer is being used as an anti-blocking additive. BYK 1679 also has applications as a silicone-containing defoamer for aqueous care products and cleaning agents, which can demonstrate its considerable defoaming effect already during production. This effect is maintained after application.
