Additives Solutions for Polyether Polyurethane Resin Systems

Polyether polyurethane resin systems are widely used in coatings, adhesives, sealants, elastomers, and foams due to their excellent flexibility, hydrolysis resistance, and low-temperature performance. However, formulating with polyether polyols presents unique challenges: air entrapment and pinhole formation, pigment settling and floating, insufficient substrate wetting, and surface defects that compromise final coating quality.

As an innovative, collaborative, and trusted partner in the chemical industry, China AAB Industry Technology Group's Member Company has specialized in the R&D, production, and sales of high-performance additives since 2006. Our additive production base holds ISO 9001, ISO 14001, and OHSAS 18001 certifications. Covering 36,630 m² with over 60 reactors and an annual capacity of 16,000 metric tons, we deliver reliable supply and customized solutions worldwide.

Our solvent-free and high-solids additives are specifically designed for demanding coating and ink systems. The product portfolio includes Wetting & Dispersing Agents, Thixotropic & Anti-Settling Agents, Defoamers, Wetting & Leveling Agents, Adhesion Promoters & Coupling Agents, Wax Additives, and Hand Feel Agents. These products are compatible with polyether polyurethane, polyester polyurethane, acrylate polyurethane, moisture-curing polyurethane, epoxy, acrylic, and alkyd resin systems.

Advantages

1. Complete Additive Portfolio for Polyether Polyurethane Systems

We offer a full range of additives covering the entire formulation chain — from pigment dispersion and rheology control to surface modification and foam elimination. This integrated approach simplifies procurement and ensures additive compatibility across the formulation.

2. High-Performance Products with Proven Stability

Our additives are engineered to deliver consistent performance in polyether polyurethane systems. The KBS-F4020 dispersant effectively reduces viscosity and inhibits floating colors in polyether polyol systems, while the KBS-C410K anti-settling thixotropic agent provides excellent anti-sagging and anti-floating performance with minimal impact on transparency, viscosity, gloss, storage stability, and curing activity.

3. Solvent-Free and High-Solids Formulations

Aligned with increasingly stringent environmental regulations, our solvent-free and high-solids additives help formulators reduce VOC emissions without compromising performance — particularly important for polyurethane coating systems where solvent content directly affects film properties and application safety.

4. Customized Solutions and Reliable Supply

With an annual capacity of 16,000 metric tons and over 60 reactors, we provide stable supply and customized solutions for customers worldwide.

Application Areas

Industrial coatings — polyurethane topcoats, primers, and clear coats

Wood coatings — furniture and flooring finishes

Automotive coatings — refinish and OEM applications

Adhesives and sealants — polyurethane-based adhesive systems

Elastomers and castings — rigid and flexible polyurethane systems

Inks — solvent-based and high-solids ink formulations

Formulating with polyether polyurethane resin systems requires additives that address dispersion stability, rheology control, surface defects, and foam management — all while maintaining compatibility with the reactive isocyanate/polyol chemistry. Our comprehensive additive portfolio provides formulators with a complete toolkit for optimizing polyether polyurethane formulations. From KBS-F series dispersants that ensure pigment stability, to KBS-C410K thixotropic agents that prevent settling, to KBS-L series leveling agents and KBS-X series defoamers that deliver defect-free surfaces, every product is engineered for consistent performance, regulatory compliance, and cost-effective formulation.
