TDS for JH-1297- 1 Anchoring Agent

‌Product Description

● JH-1297-1‌ is a pressure-sensitive adhesive type anchoring agent. Its unique structure can significantly enhance the adhesion of organic release agents/silicone to the substrate, and enhance the wear resistance of silicone release agents and silicone.

● ‌Application Scenarios‌: It can promote the adhesion of addition-cured silicone rubber to substrates such as PET and PBT; it can be used as an alternative to Dow Corning 297 anchoring agent.

Technical Specifications

Usage Instructions

Substrate Surface Treatment

To maximize bonding efficiency, all impurities such as dust, dirt, and oil stains on the substrate surface must be completely removed.

For oil stains or other potential contaminants on the substrate surface, you can use solvents like gasoline, toluene, cyclohexane for cleaning, or perform light sanding on the substrate surface, and finally wipe the surface with absolute ethanol or acetone. For substrate surfaces that are extremely difficult to bond, methods such as chemical corrosion, oxidation, or exposing the substrate surface to ultraviolet light, corona discharge, or flame sources may be required to enhance the surface activity of the substrate.

Dosage and Instruction Manual

This product is suitable for addition-cure liquid silicone systems. The recommended dosage is 1-2% of the total mass, and when the system is formulated as an A/B two-part adhesive, it should be added to the component containing the platinum catalyst.

Medium-high temperature curing at ‌120℃-180℃‌ is recommended to ensure complete curing of the silicone. When the silicon-hydrogen ratio is around ‌1.8-2.5‌, the system achieves the maximum shear strength and the highest adhesive force.

Package and Storage

The product adopts standard container packaging of ‌1kg, 2kg and 5kg‌.‌‌

Store the product in a cool, dry place. The shelf life is ‌6 months‌. Once opened, must not be exposed to air for a long time.

This series of products should be used in a well-ventilated environment. Avoid contact with skin and eyes, avoid prolonged contact with moisture in the air, keep the container sealed, and do not ingest it.
