    Waterborne Hydroxylated Polyacrylic Resin Suitable For Large-scale Component Construction

    This water-based hydroxylated acrylic dispersion is designed for formulating high-performance water-based 2K polyurethane topcoats for various metal substrates. It is compatible with both solvent-based and water-based isocyanate curing agents.


    Featuring a hydroxyl content (WEI) of 3.9%, the resin performs exceptionally well in high-temperature, low-humidity environments. It also offers cost-effective compatibility with solvent-based curing agents.

    Based on solids

    The viscosity of the product is affected by the pH value, as the pH value increases, the viscosity and thixotropy will increase.


    Key Features:‌

    Excellent compatibility with solvent-based isocyanate curing agents

    Outstanding water resistance

    Extended application period (pot life).


    Application:‌

    Prepare Curing Agent:‌ Dilute the solvent-based curing agent to 60-70% solids using a suitable co-solvent (e.g., BGA, PGDA, or PMA+DBE blend [1:2 ratio]).
    ‌Mix Components:‌ Combine Component A (main agent) and the diluted Component B (curing agent). Mix thoroughly using a pneumatic or electric stirrer.
    Control Water Dilution:‌ Add water cautiously. Dilution should not exceed 10% by weight of Component A; 5% is recommended. Higher dilution may reduce gloss.
    ‌Grinding Restriction:‌ Due to inherent instability risks during grinding that can compromise product stability, this resin is ‌not recommended‌ for use in color paste grinding processes.
