WL-AD3944 is an aqueous hydroxyl-functional acrylic dispersion designed for high-performance 2-component polyurethane coatings.
Key features include:
Rapid Drying & Recoatability: Enables quick overcoating cycles, ideal for automotive refinishing and industrial maintenance;
Multi-Substrate Compatibility: Formulates topcoats for metal/plastic/wood and primers for plastic/wood substrates;
Curing Flexibility: Compatible with water-based isocyanates (primary) or solvent-based curing agents for floor coatings;
Automotive Focus: Optimized for vehicle refit and commercial fleet refinishing operations.

Dosage and Application Guidelines
WL-AD3944 demonstrates superior thixotropic behavior and rapid compatibility with co-solvents/thickeners.
Recommended Co-solvents: DPNB, PNB, DGBE, BCS, etc.
Curing Agent Options: PGDA or PMA+DBE blends (1:1/1:2 ratio)
Important Notes:
Post-mixing of Components A/B: Elevated initial viscosity will proportionally reduce working time.
Grinding Process Limitation: Avoid incorporating this resin during paste grinding due to stability risks caused by process variability.
