1. Chemical treatment of the substrate with solvent, Cleare oil and dust . 2. Mix completely the A and B with ratio 1:1 and apply the primer by dipping, brushing, spraying or silk screen printing method.
3. Baking at 90-135℃ for 15-20mintes. 4. The primer treated substrates are processed within that day.
5. Foward the unvulcanized silicone rubber with primer-coated substrates in mouding process or hot air vulcanization.
1.Store the product in a cool, dry area away from direct heat and open flames. 2. Seal the container tightly after use to prevent evaporation. For leftover primer, store it separately to extend its shelf life. 3. This solvent is hazardous. Ensure adequate ventilation and fire safety in the working area; do not inhale fumes for long periods or let the liquid touch your skin. 4. Prior to mold curing, perform a compatibility test between the silicone primer and base materials. This primer may cause curing failure if it comes into contact with ionic compounds containing nitrogen, phosphorus, sulfur, tin, lead, mercury, antimony or bismuth.
