Primer is applied to the bonding of RTV liquid silicone rubber, liquid silicone rubber and additive silicone rubber with stainless steel (metal) When silicone rubber is cured, it releases acetic acid, which will corrode some metals. In order to achieve better adhesion, the surface of stainless steel (metal) should be treated with primer

The stainless steel (metal) surface must be free of loose particles, dry, grease or other contamination Acetone or low boiling hydrocarbon solvent can be used to clean the surface of stainless steel (metal)

Rough surface can improve bonding strength!

It is better to apply a thin layer of primer (25-50g / m2) with a brush, or spray or live immersion Since the primer is very sensitive to moisture, the impregnation shall be protected against moisture (in the air) (the container can only be opened for a short time, and the used primer cannot be poured back into the container).

After the primer is applied, Jianyi will dry at room temperature for 15-20 minutes Or drying in an oven at 60 ℃ for 5-10 minutes can shorten the drying time.

Silicone rubber shall be pasted immediately after the drying or drying process According to the bonding test results made in our laboratory, the bonding strength is better within about 8 hours after brushing the primer, and decreases after about 24 hours

Typical applications: cots, rollers, kitchen supplies, electronic appliances (maintain the original characteristics after long-term use at 220 ℃).

Primer is used for bonding room temperature silicone rubber and liquid silicone rubber to stainless steel (metal) First, apply a thin layer of primer tackifier on the surface of stainless steel (metal). After drying, vulcanize it with room temperature silicone rubber and liquid silicone rubber.
