Name: Momentive SAG 1538 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Momentive SAG 1538 Defoamer

Highly effective silicone-based defoamer for rapid foam knockdown and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylic, vinyl acetate, and styrene-butadiene emulsions.
Low dosage requirement—effective at 0.05–0.3 wt% in most polymer emulsion processes.
Thermally stable up to 120°C, maintaining performance during high-temperature polymerization and post-treatment steps.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.

Typical Applications Of Momentive SAG 1538 Defoamer

Acrylic and styrene-acrylic emulsion polymerization reactors.
Waterborne architectural and industrial coatings manufacturing.
Adhesives and sealants production, especially pressure-sensitive and construction-grade formulations.
Textile sizing and finishing baths where persistent foam interferes with uniform application.
Construction chemicals, including cementitious tile adhesives and grouts.
