Bonding Silicone & With Silicone
How to bond silicone rubber and how to use silicone adhesives for flexible, high-temperature sealing.
Bonding Silicone the Right Way
Silicone rubber is notoriously hard to bond because of its low surface energy. Success depends on the right primer or specialised adhesive. Separately, silicone adhesives themselves are ideal for flexible, high-temperature bonding of other materials.
JOME supplies silicone adhesives and guidance for both bonding to silicone and bonding with silicone.

Frequently Asked Questions
Silicone is hard to bond due to low surface energy. Use a silicone primer with a suitable adhesive, or a specialty cyanoacrylate formulated for rubber and silicone.
Use silicone adhesives when you need flexible, high-temperature, weather-resistant bonds or seals — for example in electronics, lighting and high-heat assemblies.
