Instant Adhesive Primer for Enhance Bond of Rubber, Silicone

This adhesion promoter is a high-performance surface treatment agent specifically designed to solve the industry problem of low surface energy rubber materials being difficult to wet and bond with ordinary adhesives.Application Steps:1. Clean the rubber surface.2. Apply a thin, even layer of this treatment agent.3. Allow to dry at room temperature for 5 minutes.4. Apply instant adhesive.5. Press for 5-10 seconds, allow to stand for 24 hours to reach maximum strength.Applicable Adhesive Compatibility: Recommended for use with cyanoacrylate (fast-drying/instant adhesive); for environments requiring high temperature, it can be used with epoxy resin AB adhesive (double-sided coating required).Common MisconceptionsMisconception 1: Applying instant adhesive directly to untreated silicone.Fact: Silicone has a weak boundary layer on its surface. Direct bonding without treatment will result in easy peeling after curing.Misconception 2: Treatment agent can replace adhesive.Fact: This product is a surface primer and is non-adhesive itself; it must be used with adhesive. Its function is to allow the adhesive to "grip" the rubber surface.Misconception 3: Using the same treatment agent for all rubbers.Fact: This product is suitable for low surface energy rubbers such as silicone, fluororubber. However, ordinary natural rubber and nitrile rubber have good adhesion and do not require treatment. It is recommended to test on a small area first.Precautions:1. Ensure good ventilation during use.2. If gets into eyes, rinse immediately with water.3. Unsuitable materials: Do not use on polyethylene (PE), polypropylene (PP), or fluoropolymers – these materials are difficult to bond even after treatment.

• Designed specifically for low surface energy rubbers that are difficult to bond: This adhesion promoter was developed specifically for low surface energy rubbers. It assists quick-drying adhesives in bonding rubbers by effectively changing the surface activity of the material, enabling soft and elastic rubbers that could not previously be bonded with instant adhesives or structural adhesives to bond firmly.
• Enhanced Bond Strength: After application, it forms an active film on the rubber surface, which can be used with instant adhesives to significantly improve adhesion. The bonding strength of silicone to plastics/metals can be increased by 3-5 times after treatment.
• Maintains Elastomer Flexibility: This adhesion promoter will not damage or harden the rubber surface, ensuring that flexible components such as sealing strips and silicone gaskets retain their original bending and compression properties after bonding.
• Fast Drying: Surface dry in approximately 30-60 seconds at room temperature. Equipped with a precision brush head, suitable for precise application over small areas, no heating equipment required.
• Wide range of applications: Suitable for bonding scenarios requiring high elasticity and vibration resistance, such as silicone phone case mounting brackets, automotive sealing strip splicing, and TPE soft rubber handles.
