What is kind of glue  for bonding silicone rubber openings (splitting)?

24 Apr 2017

silicone rubber

Different process or product demand situation as follows,


1, Process: cured silicone is bonded at room temperature


2, Demand silicone rubber not bonding very strong .


Method A: rapid bonding method used instant glue with silicone primer


first,cleaning surface of the silicone oil dirt, etc.

secondly,coating primer K-770 uniformly on two silicone adhesive interface,placed for 5 minutes.


In the end,uniform point glue on one silicone surface,then plying-up the two silicone rubber .


Remarks:this process is suitable for the bonding small area,it is not waterproof, high and low temperature resistance, prone to hard and brittle of finish bonding product.


Method B: RTV silicone adhesive


first,cleaning surface of the silicone oil dirt, etc.


secondly,coating RTV-silicone adhesive KN-300X uniformly on two silicone adhesive interface,keep in place or pressing 8 to 12 hours.


Remarks:It’s characterized by strong bonding strength, waterproof ,elastic bonding,temperature resistance (-60~280℃), ozoneresistance, UV-Resistance and electrical insulating property of finish bonding product.


Method C:The method is fast bonding,choose silicone hot vulcanization bonding.


first,cleaning surface of the silicone oil dirt, etc.

then ,coating KL-301G(ABC) ( application weight ratio: A:B:C=10:10:1) uniformly on two silicone adhesive interface,

heating at temperature 180°C for 10-25 seconds


Remarks : the KL-301G(ABC) applied to silicone bonding with silicone like silicone rubber ring gaskets or seals which results inwaterproof ,heat resistance ,insulation proof,moisture proof, shock absorbtion and sealing&bonding purpose.
