Name: Kemira DF-A-635 Defoamer
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Kemira DF-A-635 Defoamer

Highly effective silicone-based defoamer with rapid knock-down and long-lasting foam suppression.
Excellent compatibility with water-based systems, including high-solids and high-salinity formulations.
Low dosage requirement ensures cost efficiency without compromising performance.
Thermally stable across a broad temperature range (5–90 °C), suitable for both ambient and elevated-process conditions.
Non-hazardous formulation compliant with major global regulatory frameworks for industrial use.

Typical Applications Of Kemira DF-A-635 Defoamer

Paper and board manufacturing — particularly in coating, size press, and white water systems.
Water-based paints and architectural coatings during production and application.
Industrial cleaning formulations, including CIP (clean-in-place) and alkaline detergents.
Textile wet processing — dyeing, printing, and finishing baths.
Mineral processing slurries and flotation circuits where foam interferes with separation efficiency.
