CL-26AB-1, Silicone primer is applied for unvulcanized addition type, lsr silicone rubber with hard substrates overmold onto metallics, PA,
PET(Polyethylene terephthalate glycol ester)
1, Treat the substrates with solvent like industrial to remove dirts and oils.
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, Leave dry in room temp for 30 minutes or baking at 110-130℃ 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, Please cap its cover immediately after use to avoid volatilization.
2, Store the used and unused adhesive in separate way to lengthen the shelf life.
3, After the primer coated on the substrates, leave it volatilize completely before entering the mold, otherwise, there will be bubbles
in the finished products.
4, Wash clean the substrates to remove dirts or oil to avoid bad adhesion.
5, The PA substrates is water-absorbent, it must be dried up before molding with silicone. Better bake with 150 degrees for 1-2hours.
