How to bond silica gel to silica gel? Bonding process of silica gel and silica gel

How to bond silica gel to silica gel? There are three main bonding processes between silica gel and silica gel:

① hot-stick silicone glue. 

② normal temperature bonding is divided into slow-drying silicone glue.

③ silica gel treatment agent with quick-drying glue; first clean, then glue, and then the glue is completely cured, Check whether the silicone adhesive performance is up to standard.

Silicone and silicone bonding process:

1. Hot-stick silicone glue: clean the surface of the silicone to be bonded; apply the hot-stick silicone glue, and heat the mold to 180°C in the silicone tube machine for about 15 seconds; typically used for food-grade silicone tubes and silicone strips Synthetic silicone seal.

2. Slow-drying silicone glue at room temperature: Clean the bonding surface and apply silicone glue (the glue layer is controlled to about 1mm); use a tool or apply pressure to bond for no less than 30 minutes; it can be bonded firmly after 24 hours; it is often used in Bonding of medical silicone tubes (catheters, balloons) and other products.

3. Silicone treatment agent with quick-drying glue: Clean the surface to be bonded, apply treatment agent to the silicone to be bonded, leave it at room temperature for about 5 minutes, and apply pressure with a few drops of quick-drying glue. It can be bonded quickly in 5-10 seconds, suitable for fast bonding, but there is no waterproof, high temperature resistant silicone product bonding.

How to bond silica gel to silica gel? The bonding process of silica gel and silica gel is mainly the above three types. Different bonding process glues can meet the production requirements of silica gel products with different needs and performances, and you can choose the appropriate one according to your needs.
