DESMODUR N 3300A

DESMODUR N 3300A is an aliphatic polyisocyanate suitable for use as the hardener component for lightfast polyurethane coating systems. As a trimer of hexamethylene diisocyanate (HDI), DESMODUR N 3300A provides resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties ideal for advanced material applications. DESMODUR N 3300A can be used with polyacrylate or polyester polyols to form two-component polyurethane coatings with high lightfastness. The coatings based on DESMODUR N 3300A find wide use in automotive, transportation and industrial finishing due to their durability and ability to protect advanced material components. DESMODUR N 3300A is soluble in esters, ketones and aromatic hydrocarbons, making it easy to integrate into coating formulations for advanced material end uses.
