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.The product shall be stored in dry and shaded places and kept away from heat and fire. 2. The container must be sealed after use to prevent volatilization. Used primer should be stored separately to achieve a longer storage period. 3. As the solvent is harmful, proper ventilation and fire protection must be provided in the workplace. Long-term inhalation and skin contact shall be avoided. 4. A compatibility test shall be carried out between silicone primer and substrates before mold curing. Curing defects will occur once the primer touches ionic compounds of N, P, S, Sn, Pb, Hg, Sb and Bi.
