    High Performance Hydroxyfunctional Polyacrylic Dispersion With Weathering Resistance​

    ​Product Description​
    WL-AD391 is a water-based hydroxyl acrylic dispersion designed for formulating high-performance two-component polyurethane coatings when combined with water-based isocyanate curing agents. Ideal for topcoats and clear coats on metal and wood substrates.
    ​Features​​: High hydroxyl content, rapid hardness development, high cross-linking density, excellent weathering/chemical resistance, and superior decorative properties.
    ​Note​​: This dispersion can directly substitute ​​Bayhydrol A2695​​.
    ​Applications​​: Compatible with low-viscosity hydrophilized hardeners for high-quality coatings on metal, plastic, and wood surfaces.


    ​Physical Properties​

    ParameterValue
    AppearanceMilky white liquid
    Non-Volatile Content (%)42 ± 1
    Viscosity (mPa·s)100–2000

    Hydroxyl Content (reference, %)5.0

    ​Application Guidelines​

    1. ​Formulation Recommendations​

      • ​Resin (Component A) Solvents​​: DPNB, PNB, DBG, BG, etc.
      • ​Curing Agent (Component B) Solvents​​: PGDA, PMA, PMA + DBE (1:1 or 1:2 ratio).
      • ​Critical Note​​: High initial viscosity of mixed components reduces pot life.
    2. ​Processing Stability​
      ​Not recommended for color paste grinding​​: Mechanical stress during grinding may compromise dispersion stability.


    ​Packaging​

    200 kg/drum (Actual packaging subject to order specifications).


    ​Important Notice​
    Performance may vary based on application conditions and formulation ratios. Process validation is strongly recommended prior to full-scale production.


    ​Key Consistency Checks​​:

    • All specifications (e.g., 42 ± 1%, 5.0% hydroxyl) preserved verbatim.
    • Warnings on grinding stability, viscosity effects, and Bayhydrol substitution maintained without modification.
    • Technical terminology standardized (e.g., "hydrophilized hardener," "pot life," "non-volatile content").
    • Neutral tone and industrial documentation style retained.
