Name: Wacker PULPSIL 968 S Silicone Surfactant
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Wacker PULPSIL 968 S Silicone Surfactant

Highly effective silicone-based surfactant designed for superior foam control and surface wetting in aqueous systems.
Excellent compatibility with anionic, nonionic, and cationic formulations commonly used in pulp and paper processing.
Low dosage efficiency—delivers robust performance at concentrations as low as 0.01–0.1% active substance.
Stable under alkaline conditions (pH 7–12), making it suitable for high-pH pulping and bleaching operations.
Non-volatile, non-silicone-oil-containing formulation ensures no deposit formation or machine fouling.

Typical Applications Of Wacker PULPSIL 968 S Silicone Surfactant

Pulp washing and dewatering processes to reduce foam and improve drainage efficiency.
Bleach plant defoaming, particularly in oxygen and hydrogen peroxide stages.
Coating color and pigment dispersion stabilization in paper coating formulations.
Wet-end additive for improved sheet formation and retention in recycled fiber systems.
Deinking slurry defoaming and ink particle dispersion in deinked pulp production.
