Silicone rubber products adhere to metal, and the most critical metal surface treatment
Generally, silicone rubber products with poor adhesion to metal require treatment on the metal surface
1. Metal surface treatment: In order to achieve the best bonding effect, the metal surface must be clean and pollution-free. Sandblast with steel sand or brown corundum of 200-400 microns until the metal surface turns gray white. Recommended product: Hardware package rubber
2. After sandblasting, degrease with solvent to remove grease. Cold rolled steel is commonly treated with steel sand, stainless steel, aluminum, copper, etc., and treated with brown corundum (aluminum oxide). Phosphating treatment can also be used.
Adhesion between silicone rubber products and metals
Summary: Drill holes, knurls, and grooves in the bonding area, and use adhesive to open the Mlock (dry for 20-30 minutes). I think everyone should be very clear about the adhesive coating process.
