    APPLICATION & CHARACTERISTIC

    1. WPU-70-62I is a water-emulsifiable polyisocyanate.
    2. Cross-linking action enhances heat resistance performance, water resistance, resistance toward plasticizers and organic solvents for cement.
    3. WPU-70-62I serves as a cross-linking agent for aqueous PU dispersions.

    PROCESSING METHOD

    1. Add 3-5% WPU-70-62I by weight to the Water Based PU adhesives and mix by agitator at 300-500 RPM for 8-10 mins, use up the mixed cement within its pot life (2 hours)
    2. Add 1% more WPU-70-62I during raining days and high humid days.
    3. When mixed with PU dispersions, it will generate CO2, so don’t seal mixed cement.

     

     

    NOTICE

    1. Over exposure to water / moisture will cause the hardener turn viscous and cure itself.
    2. WPU-70-62I should be kept in tightly sealed containers at temperature between 5-40℃. Below this storage temperature WPU-70-62I may partly crystallize.
    3. When the product is transferred from one container to another, must prevent its over exposure to water, including moisture in the air .
    4. After pouring out from the original containers, containers of WPU-70-62I should be made of glass or aluminum .
    5. Close the cap of container tightly when not use, should be sealed well to prevent it reacting with moisture.
