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.Keep in dry, shaded locations. Stay clear of heat and fire sources. 2. Recap after use to stop volatilization. Store residual primer separately for longer storage. 3. Harmful solvent. Maintain ventilation and fire prevention at work. Avoid prolonged inhalation and skin exposure. 4. Test silicone primer compatibility with substrates before mold curing. Contact with N, P, S, Sn, Pb, Hg, Sb and Bi ionic compounds will impair curing.
