Köratac GM 530 is a one-step adhesion promoter that offers good hydrolysis stability and temperature stability. It has a broad adhesion spectrum, allowing for effective bonding to various thermoplastic elastomers (TPE) and thermoplastic vulcanizates (TPV) materials. This product is commonly used in the extrusion and injection molding processes of TPE and TPV materials.

    Technical Details & Test Data

    Processing Information

    Overmolding
    After complete drying (refer to the flash-off time in the technical data table), the substrate can be overmolded immediately with the thermoplastic elastomer. Thermal activation of the primed substrate to the activation temperature (surface temperature) is advantageous. The time window between adhesion promoter application and overmolding depends on process and environmental conditions as well as the thermoplastic elastomer used and must therefore be carefully determined. Any surface contamination must be strictly avoided during the entire process. Suitability tests are recommended for new materials or material changes.

    Cleaning
    Tools should be cleaned immediately after use. Once the product has cured, it can only be removed mechanically.
