High molecular weight aliphatic polyester resin offering excellent flexibility and impact resistance.
Low viscosity enables easy processing and improved formulation compatibility with isocyanates and other crosslinkers.
Hydrolysis-resistant structure ensures enhanced durability in humid or outdoor exposure conditions.
Designed for 2K polyurethane coatings requiring balanced hardness, elasticity, and weathering performance.
Free of aromatic monomers — supports low-yellowing and superior UV stability in clear and pigmented systems.
Automotive refinish clearcoats and basecoats requiring high gloss and chip resistance.
Industrial maintenance coatings for metal substrates exposed to harsh environmental conditions.
High-performance wood coatings where flexibility and adhesion to complex contours are critical.
Plastic coatings for automotive interior trim and consumer electronics housings.
UV-curable hybrid polyurethane-polyester topcoats for decorative and protective finishes.
