Description

The Desmodur D series are water dispersible crosslinkers based on hexamethylene diisocyanate for adhesives systems.

Desmodur DA-L: Solvent-free liquid polyisocyanate, emulsifiable in aqueous polymer dispersions. It can be used as a crosslinking agent for largely pH-neutral aqueous polymer dispersions, such as polyurethane, polyvinylacetate, polyacrylate and synthetic rubber dispersions. Its high functionality produces improved water resistance. Desmodur DA-L reacts under ambient conditions and improves the resistance of adhesive bonds to moisture, heat, plasticizers and many solvents.

Desmodur DN: Solvent-free liquid polyisocyanate, emulsifiable in aqueous polymer dispersions. It has lower viscosity for improved dispersibility. It can be used as a crosslinking agent for largely pH-neutral aqueous polymer dispersions, such as polyurethane, polyvinylacetate, polyacrylate and synthetic rubber dispersions. Desmodur DN is not prone to turbidity at low storage temperatures. Crosslinking increases resistance of bonds to heat, water, plasticizers and many solvents .
