6910A is a premium, solvent-free wetting and dispersing additive specifically engineered for high-performance epoxy resin systems. As a high-molecular-weight copolymer featuring multiple pigment-af…
Exceptional Viscosity Reduction: Significantly lowers the viscosity of epoxy mill-bases, enabling higher pigment and filler concentration without increasing Newtonian flow resistance.
Superior Pigment Stabilization: Provides robust steric hindrance to prevent the flocculation of inorganic pigments, ensuring long-term shelf stability and consistent color.
Enhanced Surface Quality: Improves leveling and reduces the risk of surface defects like craters, flooding, or floating in multi-pigment systems.
Economic Efficiency: Faster wetting reduces grinding time and energy consumption while increasing total throughput.
Versatile Compatibility: 100% active matter content ensures full compatibility with various solvent-free and solvent-borne epoxy resins, maintaining film integrity across diverse industrial formulation requirements.
规格
技术亮点
Chemical Identity: A high-performance solution of a salt of unsaturated acidic polycarboxylic acids or a modified block copolymer with pigment-affinic groups.
CAS Verification: As a proprietary polymeric mixture, 6910A lacks a single CAS number; its constituent monomers are globally compliant.
