Desmodur® ultra DA-L

Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate.Desmodur® ultra DA-L is a 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.
