Hydrophilic aliphatic polyisocyanate based on hexamethylene diisocyanate for curing agents in water-based two-component polyurethane systems.

Hodhyate® 8487 generally has good compatibility with the following organic solvents: such as esters and ether esters. However, the solubility/miscibility of the solution must be tested in any case. Only polyurethane grade solvents (water content <0.05) %).

Hydrophilic isocyanate is very sensitive to moisture and forms carbon dioxide and insoluble urea with water. The container must be kept well at all times. Any form of moisture (moisture solvents and moisture-containing substances) must be avoided because the carbon dioxide produced by the reaction with water can cause Container pressure rises, color darkens and Viscosity increases
