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

Hodhyate® 8310 generally has good compatibility with the following organic solvents: such as esters, ether esters, xylene and solvent naphtha 100. However, the solubility/miscibility of the solution must be tested under any circumstances. Use polyurethane grade solvent (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.
