Name: Dow DOWSIL 55 Additive Leveling Agent
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL 55 Additive Leveling Agent

Enhances surface uniformity and eliminates orange peel in silicone-based coatings and sealants.
Improves flow and leveling without compromising pot life or cure kinetics.
Compatible with both addition-cure and condensation-cure silicone systems.
Reduces surface tension effectively at low addition levels (typically 0.1–0.5 wt%).
Non-volatile and thermally stable up to 200 °C, supporting high-temperature processing.

Typical Applications Of Dow DOWSIL 55 Additive Leveling Agent

Automotive silicone RTV gaskets and under-hood sealing compounds.
Architectural silicone sealants for façade and glazing systems.
Electronics encapsulants and conformal coatings requiring defect-free surfaces.
Industrial coatings for metal and plastic substrates where gloss and smoothness are critical.
Medical-grade liquid silicone rubber (LSR) formulations for precision molded parts.
