Name: Dow DOWSIL AFE-3101 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL AFE-3101 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage efficiency—effective at 0.05–0.3 wt% in most formulations—minimizing impact on final product properties.
Thermally stable up to 120°C, supporting high-temperature processing conditions without degradation.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.

Typical Applications Of Dow DOWSIL AFE-3101 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Water-based adhesives and sealants, including pressure-sensitive and construction-grade formulations.
Textile and leather finishing auxiliaries requiring foam control during padding and coating processes.
Construction chemicals such as cementitious tile adhesives, grouts, and self-leveling underlayments.
