Desmodur XP 2599 is an aliphatic prepolymer containing ether groups and based on hexamethylene-1,6-diisocyanate (HDI).
It is suitable as a hardener for solvent-free polyurethane coatings.

Storage Conditions

Desmodur XP 2599 should be stored in tightly sealed original containers and protected from moisture, heat, and foreign materials. The product is sensitive to moisture and should therefore be stored in tightly sealed containers. Storage at elevated temperatures will lead to an increase in viscosity and a reduction of the NCO content. Recommended storage temperature is 10º-25ºC.
