Additives Solutions for Polyether Polyurethane Resin Systems

This series of additives is specifically developed for polyether-based polyurethane resin systems and is suitable for applications such as polyurethane coatings, inks, adhesives, and sealants. The product range encompasses four major categories—wetting and dispersing agents, anti-settling and thixotropic agents, wetting and leveling agents, and defoamers—offering comprehensive additive solutions for polyether polyurethane systems, covering everything from pigment dispersion and anti-settling/anti-sagging performance to surface wetting, leveling, and foam control.

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.
