WL-AD391 is a waterborne hydroxyl-functional acrylic dispersion engineered for formulating premium two-component polyurethane (2K PU) coatings when crosslinked with water-based isocyanate curing agents. Designed for demanding topcoat/clearcoat applications across metal and wood substrates, it delivers exceptional performance through:
Key Features
Recommended Applications
Competitive Advantage
Direct replacement for Bayhydrol® A2695 with equivalent rheology and compatibility profiles.
Optimal Formulation
Pair with low-viscosity hydrophilized hardeners for high-quality coatings on metal, plastic, and wood surfaces.

|
Appearance |
Milky white liquid |
|
Non-Volatile content(%) |
42±1 |
|
Viscosity(m Pa · s) |
100~2000 |
|
PH |
7.5~8.5 |
|
Hydroxyl content (reference value, %) |
5.0 |
Main Agent (Component A): DPNB, PNB, DBG*, BG
Curing Agent (Component B): PGDA, PMA, or PMA+DBE blend (1:1 or 1:2 ratio)
Critical Processing Notes:
Pot life decreases proportionally with elevated initial viscosity post-mixing (A+B components)
Avoid resin incorporation during color paste grinding - inherent process instability may compromise final product stability
