Isocyanate series

HD-8310

Properties

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

Physical property Theoretical value
Viscosity(25℃) 2000-4000 mPa•s
ω (-NCO) /% 16.8-17.8%
Hazen color value ≤100
HDI monomer content <0.15
Solid content (%) 100%

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.

Storage Stored in a sealed container; Recommended storage temperature: 0-30 °C; Avoid strong moisture, heat and foreign substances; Storage period: 6 months
Application Hodhyate® 8310 is a crosslinker for water-based coatings. Hodhyate® 8310 is easy to emulsify in water-based media due to Hydrophilic. Hodhyate® 8310 can also be added to traditional hydroxyl-free dispersions to improve its properties.
