CL-26AB-8, Silicone primer, is mainly applied for platinum curing agent-added HTV /LSR silicone overmold onto PA(Nylon), Metallics, Polyester,
PET, Bakelite, Epoxy, FRP(Fibre glass) etc, which will result in a tight bond after molding process.
Good adhesion Strength
4 Hours water- boiling Tests
No primer trace on finished silicone products
Appearance：Transparent or Pasty gel
Specifical gravity : 0.95 g/cm3
Shelf life：Six months without cover opened（25℃）.
1,Coating the CL-26AB-8 on the edge of the glass
2,Direct the LSR silicone on the edge the glass in the injection moulding machine ,
apply 120～180℃ degrees for 1-3 minutes to vulcanize the silicone rubber .
3,Trim the rough edges and wash clean the glass covers
4, Place the glass covers in the ovens , apply 180～220℃ for 1- 2 hours , a silicone glass cover is done made .
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.
