Bio-based aliphatic polyisocyanate (PDI). As the hardener component for lightfast polyurethane coating systems
Desmodur CQ ultra N 7500 is used primarily as the hardener component for lightfast two-component polyurethane
coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical
properties. Preferred co-reactants are polyacrylate or polyester polyols.
Partially bio-based, using segregated feed stocks as raw material, linking circularity created by nature (photosynthesis) with
high-performance materials.
