Name: DOW DOWSIL 31-441 Additive
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of DOW DOWSIL 31-441 Additive

Enhances flow and leveling in silicone-based coatings and sealants.
Improves substrate wetting on low-surface-energy materials including plastics and fluoropolymers.
Reduces surface defects such as craters, orange peel, and pinholes.
Compatible with both addition-cure and condensation-cure silicone systems.
Non-reactive modifier—does not participate in curing chemistry and maintains formulation stability.

Typical Applications Of DOW DOWSIL 31-441 Additive

Automotive silicone sealants for body assembly and lighting modules.
Industrial protective coatings requiring uniform film formation on complex substrates.
Electronics encapsulants and potting compounds where defect-free surfaces are critical.
Architectural glazing sealants applied to anodized aluminum and coated glass.
Medical device silicone adhesives requiring consistent interfacial performance.
