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.
