KBS Additives solutions for Solvent-Free Polyurea Coatings

The series are designed for solvent-free polyurea coatings, floorings, waterproofing systems, thick-film applications, and formulations based on polyether, polyester, hydroxypropylene and castor oil systems. Its core performance targets are: viscosity reduction, anti-floating and anti-discoloration, gloss stabilization, anti-settling, sag resistance, wetting and leveling, and defoaming without cratering.

Series Portfolio

Dispersants: Stable Color, Lower Viscosity and Better Gloss

Solvent-free polyurea systems often require high filler loading and stable pigment dispersion. Poor dispersion can lead to high viscosity, settling, floating color, gloss loss and uneven surface appearance. The KBS dispersant range offers targeted solutions:

• KBS-F5050 — General-purpose and cost-effective viscosity-reducing dispersant.
• KBS-F4020 — Modified polyurethane dispersant. Inhibits floating color, stabilizes gloss, reduces inorganic viscosity and improves organic dispersion.
• KBS-F0200 — Acid polyester dispersant for polyether polyurethane systems. Strong viscosity reduction.
• KBS-F110K — Acid polyester dispersant. Provides gloss, viscosity reduction and excellent color spreading in white top coats. General purpose for polyether, polyester, hydroxypropylene and castor oil systems.
• KBS-F1610A — Modified polyurethane polymer additive for efficient dispersion of organic pigments, inorganic pigments and carbon black.
• KBS-F104S — Silicone compound for anti-floating and anti-discoloration. Can be added before or after.

Recommended for: solvent-free polyurea topcoats, self-leveling systems, pigmented coatings, carbon black systems, color pastes and formulations requiring gloss stability.

Thixotropic Agents: Anti-Settling, Sag Resistance and Color Uniformity

• KBS-C410K is an organic polyurea thixotropic agent designed for solvent-free polyurea systems.
• KBS-C3120X is a polyamide wax paste thixotropic agent.

These products help improve anti-settling performance, sag resistance and color uniformity in solvent-free polyurea coatings.

Recommended for: solvent-free polyurea coatings and floorings where storage stability, vertical sag resistance and color uniformity are required.

Wetting Agents: Improved Surface Wetting and Leveling

Surface defects such as poor wetting, shrinkage, orange peel and uneven leveling are common in solvent-free polyurea coatings. KBS wetting agents help achieve a smooth, uniform and high-quality finish.

• KBS-L333K — Polyether modified silicone wetting agent.
• KBS-L3310 — Polyether modified silicone wetting agent.
• KBS-L358A — Polyacrylate solution wetting and leveling agent.
• KBS-L3777 — Fluorine-modified acrylate solution wetting and leveling agent.

Recommended for: solvent-free polyurea topcoats, self-leveling systems, thick-film coatings and systems requiring improved wetting and leveling.

Defoamers: Strong Foam Control Without Cratering

Solvent-free polyurea systems are often thick, high-solids and prone to entrapped air. Poor defoamer selection can cause cratering, pinholes, poor compatibility and surface defects. KBS defoamers are designed to balance defoaming power, compatibility and surface quality.

• KBS-X052 — Polyacrylate defoamer.
• KBS-X066N — Fluorine-modified silicone defoamer.
• KBS-X6800A — Modified silicone. Excellent defoaming and foam inhibition.
• KBS-X053 — Non-silicone defoamer.

Recommended for: solvent-free polyurea thick coatings, self-leveling systems and formulations requiring strong foam control.
