Name: Dow DOWSIL Q2-3315 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL Q2-3315 Defoamer

High-efficiency silicone-based defoaming agent designed for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylic, styrene-acrylic, and vinyl acetate emulsions.
Low dosage requirement—effective at 0.05–0.3 wt% in final formulation—minimizing impact on product clarity and rheology.
Thermally stable up to 120°C, maintaining performance during high-temperature processing and storage.
Non-yellowing and non-silicone-residue-forming, supporting clear coatings and sensitive pigment dispersions.
