Name: KS Chemical Rheoflow AF-770 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of KS Chemical Rheoflow AF-770 Defoamer

Highly effective silicone-polyether hybrid defoamer with rapid knock-down and lasting foam suppression.
Excellent compatibility with water-based systems, including acrylic, vinyl acetate, and styrene-butadiene emulsions.
Low dosage efficiency—effective at 0.05–0.3 wt% in most formulations without affecting gloss or film integrity.
Thermally stable up to 120°C, suitable for high-temperature polymerization and post-addition processes.
Non-silicone residue formulation minimizes surface defects such as craters, pinholes, and crawling in finished coatings.

Typical Applications Of KS Chemical Rheoflow AF-770 Defoamer

Architectural and industrial waterborne paints and coatings.
Adhesives and sealants based on synthetic latex and PVA dispersions.
Construction chemicals including cementitious grouts, tile adhesives, and self-leveling underlayments.
Textile printing pastes and pigment dispersions.
Water-based wood finishes and clear varnishes.
