Desmodur® DA-L

Covestro (formerly Bayer MaterialScience) 科思创

Desmodur® DA-L is a ydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate. Desmodur® DA-L is a solvent-free liquid polyisocyanate, emulsifiable in aqueous polymer dispersions. Any occasional turbidity or precipitation visible is caused by very small amounts of processing aids. These have no adverse effect on the processing and final properties of the cured adhesives. It can be used as a crosslinking agent for largely pH-neutral aqueous polymer dispersions, such as polyurethane, polyvinylacetate, polyacrylate and synthetic rubber dispersions. Crosslinking raises the resistance of the bonds to heat, water, plasticizers and numerous solvents. This product has an NCO content of 20.0 ± 1%, a viscosity at 23°C of 3,000 ± 600 mPa·s, and a monomeric HDI of = 0.25%.
