Summary: | A UV-resistant coating composition for protecting polyurethane surfaces, especially in a marine environment above the sea-air interface (so-called "splash zone"), is formed from an amorphous hydrophobic dimer fatty acid-based polyether polyol and an aliphatic isocyanate, such as hexamethylene diisocyanate, and may include a UV blocking agent such as titanium dioxide. The polyol may be modified with a chain extender. The composition provides an elastomeric protective barrier against the deleterious effects of UV exposure, and is useful on polyurethane surfaces on bend stiffeners, buoys etc. |
