Why is the primer sprayed on the surface of silicone rubber before bonding?
09 Jun 2023
Silicone rubber is a kind of polymer material, which is widely used in industrial production.
Why is the primer sprayed on the surface of silicone rubber before bonding?
Silicone primer is a special chemical agent, which is a material specially used to improve the surface properties of silicone to improve its bonding performance. Primers create a hydroxide layer on the silicone surface, which makes the silicone surface more reactive, allowing for better contact with other materials and improving bond strength.
And the application of silicone primer is very helpful for the bonding of silicone:
1. The shear strength and bonding strength of silica gel itself are limited during bonding. Using silica gel treatment agent stimulates the surface activity of silica gel, which can help improve its bonding strength and prevent detachment and sliding.
2. After the silica gel is treated with a treatment agent, it takes much less time to contact with other materials, which can greatly shorten the time of silica gel bonding and improve production efficiency.
Therefore, when dealing with complex silicone bonding operations, the use of silicone primer can not only improve production efficiency, but also ensure the stability and reliability of the bonding effect, thereby further improving product quality.
