Name: Elementis Defom 8700 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Elementis Defom 8700 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down and long-term foam suppression.
Excellent compatibility with water-based systems, including acrylics, vinyl acetate copolymers, and styrene-butadiene emulsions.
Low dosage efficiency — achieves optimal performance at 0.05–0.3% w/w in most formulations.
Thermally stable up to 120°C, supporting high-shear and elevated-temperature processing conditions.
Non-yellowing and non-staining, preserving clarity and color integrity in sensitive coatings and adhesives.

Typical Applications Of Elementis Defom 8700 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers, and topcoats).
Adhesives and sealants, particularly PVA-based and synthetic rubber emulsions.
Construction chemicals including cementitious mortars, tile adhesives, and self-leveling compounds.
Textile printing pastes and pigment dispersions requiring low-foam rheology control.
Water treatment formulations where persistent foam interferes with clarification or dosing accuracy.
