CL-26AB-25 is applied as silicone bonding primer for platinum addition type LSR Silicone or HTV Silicone overmold onto PC, toughened glass, etc.
It serves as an extra clear coating on the PC substrates which result in a tight bond with lsr silicone after molding process , Typical application on
silicone electronic products ,silicone diving equipments ,etc.
3 times repetitive standard tests
Making your silicone products 99% ok rates
Survive In Rugged Environment
Water resistance, anti-salt mist ,
chemicals resistance, anti-oils, solvent ,etc.
Good adhesion Strength
No partial bonding failure
No primer trace on finished silicone products
Color: Transparent Liquid or Gel
Component：A:Gel, B:Platinum Catalyst
Mixing Ratio: A:B=1:1（Use up within 4hours after mixture）
Storage: 6 Months(20℃-25℃ avoid light, heat and place in dry area)
1、 Surface Treatment：Chemical treatment with the substrate, remove oil and dust.
2、 Apply The Glue: Mix A and B evenly then apply the primer on the substrates by brusing, dipping, spraying or screen printing
3、 Surface Dry: Heat up with 90℃-130℃ for 10~15minutes。
4、 Leavy Dry: The primer-coated substrates should be forwarded to moulding process with silicone right in the day and avoid pollution and
contact with high temperature and humidity.
5、 Curing: Join the silicone with primer coated substrates and forward to moulding process for hot air vulcanization.
1, Keep in dry and shade place and avoid fire and heat
2, The solvent is volatile, please fasten down the cap after use
3, The steam issued by the solvent is harmful, the working shop should be fireproof and avoid long time inhalation and contact with skins
4, Lightly Cloudy won’t affect the performance.
5, While curing, the product should avoid contact with organic compound which contain substance like N, P, S and heavy metallic anionic compounds like Sn、Pb、Hg、Sb、Bi、As and compounds which contains acetenyl Otherwise, the primer will result in bad cure, thus, test for the compatibility of primer with substrates is necessary
