Highly reactive aliphatic polyester polyol with terminal hydroxyl functionality for fast-curing systems.
Excellent hydrolytic stability due to saturated backbone and absence of ester groups prone to degradation.
Low viscosity enables easy handling, efficient mixing, and improved filler incorporation in formulations.
Designed for compatibility with isocyanates in high-performance polyurethane coatings and adhesives.
Consistent batch-to-batch quality supported by Covestro’s stringent GMP-aligned manufacturing control.
High-gloss, weather-resistant topcoats for automotive OEM and refinish applications.
Durable protective coatings for industrial metal and plastic substrates.
Two-component polyurethane adhesives for demanding bonding in transportation and construction.
Flexible yet abrasion-resistant clearcoats for flooring and decorative surfaces.
