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.WARNING: Store only in dry, shaded areas. Strictly keep away from heat and open fire. 2. WARNING: Tighten the cap after use to prevent volatile substances from escaping. Separate storage of used primer is required for prolonged preservation. 3. DANGER: Solvent is harmful. Work areas must be ventilated and fireproof. Do not inhale vapors repeatedly or allow skin contact. 4. CAUTION: Test silicone primer against substrates prior to mold curing. Contact with N, P, S, Sn, Pb, Hg, Sb and Bi ionic compounds will cause incomplete curing.
