General Characterization
Desmodur E 30700 is an aliphatic ester groups containing prepolymer based on hexamethylene-1,6-diisocyanate (HDI).
It is suitable for use as a hardener for solvent-free polyurethane coatings.
It is suitable for use as a hardener for solvent-free polyurethane coatings.
Storage Conditions
Desmodur E 30700 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 20º-30ºC.
Storage at low temperature - below 20°C - may lead to turbidity and crystalline separation. By careful heating up to a maximum of 50 °C the product can usually be melted again. Afterwards the product has to be homogenized.
