Name: Dow DOWSIL FS OC-2 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL FS OC-2 Defoamer

Highly effective silicone-based defoamer designed for rapid foam knockdown and long-term foam suppression in demanding aqueous systems.
Excellent compatibility with waterborne coatings, adhesives, and industrial cleaning formulations without compromising clarity or stability.
Low dosage efficiency—effective at concentrations as low as 0.05–0.3 wt%—minimizing formulation impact and cost-in-use.
Thermally stable up to 120°C, supporting high-temperature processing and curing conditions commonly used in industrial applications.
Non-yellowing and inert in final formulations, ensuring no adverse effect on color, gloss, or substrate adhesion.

Typical Applications Of Dow DOWSIL FS OC-2 Defoamer

Waterborne architectural and industrial coatings (e.g., acrylic, epoxy, and polyurethane dispersions).
Adhesives and sealants, including pressure-sensitive adhesives (PSAs) and latex-based bonding agents.
Industrial and institutional (I&I) cleaning solutions, especially alkaline detergents and CIP formulations.
Textile auxiliaries such as dyeing assistants, softeners, and printing pastes.
Construction chemicals, including cementitious grouts, tile adhesives, and self-leveling underlayments.
