Name: Chemipol DENSIPOL PA 318 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Chemipol DENSIPOL PA 318 Defoamer

Highly effective silicone-polyether hybrid defoamer with rapid knock-down and long-term foam suppression.
Excellent compatibility and stability in water-based polymer emulsions, including acrylics, styrene-butadiene, and vinyl acetate systems.
Low dosage efficiency—typically effective at 0.05–0.3 wt% active addition level relative to total formulation.
Non-yellowing and non-staining; maintains clarity and color stability in sensitive coatings and adhesives.
Resistant to shear degradation and stable across a broad pH range (pH 4–12) and temperatures up to 90°C.

Typical Applications Of Chemipol DENSIPOL PA 318 Defoamer

Architectural and industrial waterborne paints and coatings.
Adhesives and sealants, especially pressure-sensitive and construction-grade formulations.
Textile and leather finishing auxiliaries, including dye baths and softener concentrates.
Water-based polymer emulsion production (e.g., SBR, VAE, acrylic dispersions).
Industrial cleaning formulations and metalworking fluid concentrates.
