Name: Wacker SC120 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Wacker SC120 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage requirement — typically effective at 0.05–0.3 % w/w in final formulation.
Stable under shear and elevated temperature conditions common in industrial polymerization and coating processes.
Non-yellowing and does not impair gloss or film integrity in finished coatings and adhesives.

Typical Applications Of Wacker SC120 Defoamer

Architectural and industrial waterborne paints and coatings.
Adhesives and sealants based on synthetic dispersions (e.g., SBR, VAE, acrylic).
Textile and leather finishing formulations.
Construction chemicals including cementitious slurries and tile adhesives.
Water treatment systems requiring controlled foam management during processing.
