2. The bonding surface of the substrate must be thoroughly cleaned with a solvent or a suitable cleaning agent to keep dry and to prevent pollution, and sizing within 30 minutes after cleaning; the suitable construction temperature is 6 ºC ~ 40 ºC 3. Sizing must ensure that the gap is fully filled to make the adhesive layer dense, closely contact the surface of the substrate, and trimmed before the colloid is not cured to ensure a smooth and beautiful appearance |
