Name: Spredox D-140 Dispersant
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Spredox D-140 Dispersant

High-efficiency steric stabilization for inorganic pigments and fillers in aqueous systems.
Excellent compatibility with acrylic, styrene-acrylic, and vinyl acetate-based emulsion polymers.
Low foaming profile, minimizing process interruptions during high-shear dispersion and grinding.
Enhanced storage stability of pigment concentrates and architectural coatings without viscosity drift.
pH-stable across 6.5–9.5, supporting broad formulation flexibility without post-adjustment.

Typical Applications Of Spredox D-140 Dispersant

Architectural waterborne paints (flat, satin, and semi-gloss interior/exterior formulations).
Industrial maintenance coatings requiring long-term pigment suspension and gloss retention.
Water-based printing inks for flexographic and gravure applications on porous substrates.
Construction chemicals including tile adhesives, grouts, and cementitious waterproofing slurries.
Functional coatings such as fire-retardant intumescents and anti-corrosive primers.
