FAQ
Under standard conditions (23°C, 50% RH), WBP-45 achieves a skin strength sufficient for road-load driving — defined as ≥ 0.35 MPa lap-shear on primed glass — within 60 minutes. At 10°C / 30% RH, allow 90–120 minutes. Cure is driven solely by atmospheric and glass-surface moisture; no heat or UV activation is required.
