BYK-141 defoamer is a silicone-based defoamer used in solvent-borne, low to high polarity coating systems and printing inks.
BYK-141 defoamer has excellent compatibility and is suitable for post-addition.
Product Name: BYK-141
Application Type: Defoamer
Appearance: Colorless liquid
Chemical Nature: Defoaming polymer and polysiloxane solution.

BYK-141 defoamer is a silicone defoamer for solvent-borne systems, applicable in general industrial coatings, paper coatings, floor coatings, and curtain-coated wood coatings.
Suitable binders for BYK-141 additive include oil-free polyesters, vinyls, polyurethanes, epoxy esters, nitrocellulose, and acid-curing systems.
BYK-141 additive can be used in anticorrosive and marine coatings, architectural coatings, automotive OEM coatings, automotive refinish paints, can coatings, wood and furniture coatings, floor coatings, curtain-coated wood coatings, paper coatings, industrial coatings, room temperature curing systems, and printing inks.
BYK-141 defoamer should be added to the grinding material before grinding. If added at a later stage, sufficient high shear must be applied to ensure good dispersion of the defoamer and prevent cratering. The full effect of the defoamer is achieved 24 hours after incorporation into the system.
