‌ WL-AD3947‌, a waterborne hydroxyl-functional acrylic dispersion, is recommended for producing high-performance two-component polyurethane coatings when crosslinked with water-based isocyanate curing agents . Its formulation targets premium topcoats and protective varnishes for diverse metal surfaces.

This aqueous hydroxyl acrylic dispersion delivers exceptional water, salt spray, acid, and alkali resistance, with extended initial water resistance retention. It is ideally suited for outdoor applications. Compatible with both oil-based and water-based curing agents, it functions as a versatile topcoat, varnish, or combined basecoat/topcoat resin.

Physical Property

Integration of Primer and Topcoat Testing Results‌

‌Topcoat:‌ WL-AD3947 Polyurethane Primer/Topcoat (Light Gray)
‌Curing Agent:‌ WL-AC300 Primer/Topcoat Special Hardener
‌Mix Ratio:‌ 4:1
‌Pinhole Limit:‌ 85 µm
‌Drying/Curing Process:‌
Bake at 80°C for 2 hours, then cure for 3-7 days;

OR Bake at 80°C for 4 hours, then cure for 1 day prior to salt spray testing.

The measured results are as follows:

Performance Features:‌

• Excellent aging resistance and salt spray resistance.
• Good adhesion to various substrates.
• High cost performance.
• Good initial water resistance.

‌Dosage and Application Method:‌

• ‌Mixing:‌ WL-AD3947 is designed to be combined with a waterborne isocyanate curative (hardener).
• ‌Main Agent Co-solvents:‌ Recommended co-solvents for WL-AD3947 (Component A) include DPNB, PNB, DBG, and BG.
• ‌Curative Co-solvents:‌ Recommended co-solvents for the curative (Component B) include PGDA, PMA, or a blend of PMA + DBE (in ratios of 1:1 or 1:2).
• ‌Pot Life:‌ If the initial viscosity of the mixed A/B components is too high, the pot life (application window) will be correspondingly shortened.
• ‌Grinding Warning:‌ Grinding WL-AD3947 into a paste is ‌not recommended‌. The grinding process introduces numerous destabilizing factors which may compromise the product's stability and lead to performance degradation.
