Name: Generic HY-1040C Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Generic HY-1040C Defoamer

Highly effective silicone-based defoaming agent with rapid knock-down and lasting foam suppression.
Excellent compatibility with water-based systems, including acrylic, styrene-acrylic, and vinyl acetate emulsions.
Low dosage requirement — typically effective at 0.05–0.3 wt% in formulation.
Thermally stable up to 120°C, maintaining performance during high-shear mixing and elevated processing temperatures.
Non-yellowing and non-silicone-residue-forming, ensuring clarity and stability in sensitive coatings and adhesives.

Typical Applications Of Generic HY-1040C Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers).
Water-based adhesives and sealants (e.g., PVA, EVA, and acrylic dispersions).
Textile printing pastes and pigment dispersions.
Construction chemicals, including cementitious tile adhesives and self-leveling underlayments.
Wood coatings and clear finishes where surface defect prevention is critical.
