Name: VOK VOK-2018 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of VOK VOK-2018 Defoamer

High-efficiency silicone-based defoaming agent with rapid knock-down and lasting foam suppression.
Excellent compatibility with water-based systems, including acrylics, polyvinyl acetate (PVAc), and styrene-butadiene emulsions.
Low dosage requirement—effective at 0.05–0.3% w/w in most formulations—minimizing cost-in-use and avoiding surface defects.
Thermally stable up to 120°C, supporting high-temperature processing in industrial coating and adhesive manufacturing.
Non-hazardous, VOC-free formulation compliant with major global regulatory frameworks including REACH and RoHS.

Typical Applications Of VOK VOK-2018 Defoamer

Architectural and industrial waterborne coatings (e.g., interior/exterior paints, primers, and topcoats).
Water-based adhesives and binders used in packaging, laminating, and wood composite production.
Textile printing pastes and pigment dispersions where bubble entrapment affects print clarity and color uniformity.
Construction chemicals such as cementitious tile adhesives, grouts, and self-leveling underlayments.
Industrial cleaning formulations and metalworking fluid concentrates requiring stable foam control during recirculation.
