KBS Additives solutions are developed specially for water-based two-component epoxy formulations. This integrated platform covers four essential functions: dispersants, anti-settling and thixotropic agents, wetting and leveling agents, and defoamers. It addresses common challenges such as pigment dispersion, color floating and flooding, settling, sagging, poor substrate wetting, shrinkage, orange peel, foam, cratering, and stability under high pH and alkaline conditions. Suitable for water-based 2K epoxy self-leveling floors, primers, topcoats, color pastes, and inorganic flooring, the series helps simplify additive selection, improve compatibility, and enhance storage stability and application performance.
The series is designed for water-based 2K epoxy coatings, color pastes, inorganic flooring, and systems requiring broad compatibility with inorganic pigments, organic pigments and carbon black. Its core performance targets are: universal pigment dispersion, anti-floating and anti-flooding, anti-settling and anti-sagging, dynamic and static surface tension reduction, foam inhibition, and compatibility in water-based systems.

Dispersants: Universal Color Paste Dispersion and Stability
Water-based two-component epoxy systems require dispersants that can handle inorganic pigments, organic pigments and carbon black while maintaining stability in water-based color pastes. Poor dispersion can lead to floating, flooding, settling and gloss loss.
