Silicone products are widely used in medical, electronic and automotive fields because of their excellent flexibility and chemical stability.However, the surface energy of silicone is low, resulting in poor bonding performance.The emergence of silane coupling agents has brought new breakthroughs to the surface treatment of silicone products, which has significantly improved the bonding strength and durability.


Mechanism of action of silane coupling agent


Interface modification: The silane coupling agent forms a layer of active groups on the surface of the silicone through a chemical reaction to improve its surface energy and enhance its compatibility with the adhesive.


Chemical bonding: The silane coupling agent can form a chemical bond between the silicone and the adhesive, which significantly improves the bonding strength and durability.


Application effect of silane coupling agent


Improve the bonding strength: Through the treatment of silane coupling agent, the bonding strength of silicone products can be increased by more than 50%.For example, in automotive seals, the bonding strength of silicone treated with silane coupling agent to metal is significantly enhanced.


Enhanced durability: Silicone products treated with silane coupling agent can still maintain stable bonding performance in high temperature and humidity environments.For example, in medical catheters, the bonding durability of silicone and plastic treated with silane coupling agents is significantly improved.


Technological breakthroughs and future prospects


Multifunctional silane coupling agent: Develop silane coupling agents that enhance adhesion and other functions (such as antibacterial and conductive) to meet diverse needs.


Environmentally friendly silane coupling agent: Develop low-VOC, water-based silane coupling agent to reduce environmental pollution.


Silane coupling agents have brought revolutionary breakthroughs to the surface treatment of silicone products, significantly improving the bonding strength and durability.With the advancement of technology, the application of silane coupling agents will be more extensive and efficient.
