    Isocyanate series

    HD-8487

    Properties

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

    Physical property Theoretical value
    Viscosity(25℃) 4500-6500 mPa•s
    ω (-NCO) /% 20-21%
    Hazen color value ≤100
    HDI monomer content <0.15
    Solid content (%) 100%

    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

    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? 8487 is a cross-linking agent for water-based systems with high miscibility and chemical resistance. The dispersibility of products in water is affected by organic cosolvents. Uses high hydrazine or high hydrophilic Solvents such as butyl acetate, xylene, butyl glycol acetate, dimethylformamide or N-methylpyrrolidinium will form a coarse dispersion, which may lead to turbid film.
