DESMODUR ULTRA DN

DESMODUR ULTRA DN is a solvent-free liquid polyisocyanate that is emulsifiable in water. It can be used as the crosslinker for largely pH-neutral aqueous polymer dispersions including polyurethane, polyvinyl acetate, polyacrylate and synthetic rubber dispersions. Crosslinking increases the resistance of the bonds to heat, water, plasticisers and many solvents. Compared with Desmodur DA, DESMODUR ULTRA DN is characterised by its much lower viscosity and is not prone to turbidity at low storage temperatures. DESMODUR ULTRA DN provides excellent bonding strength and durability for applications. Its low viscosity and emulsifiability in water allows for easy application and uniform distribution. The crosslinking property of DESMODUR ULTRA DN enhances long-term performance of materials by improving resistance to environmental factors.
