Köratac GM 600

1 of 40 products in this brand
Köratac GM 600 is a one-step, water-based adhesion promoter used for extrusion and injection molding of thermoplastic elastomers (TPE). It offers good hydrolysis stability and temperature stability. This product is fluorescent, and its primary purpose is to enhance the adhesion of TPE materials during manufacturing processes.

Functions: Adhesion Promoter

Compatible Polymers & Resins: Styrene Ethylene Butylene Styrene (SEBS), Thermoplastic Elastomers (TPE), Thermoplastic Starch (TPS), Thermoplastic Vulcanizates (TPV)

Processing Methods: Extrusion, Injection Molding

End Uses: Automotive Window Encapsulation, Connectors, Plugs

    Injection molding

    After drying is completed (refer to flash-off time / waiting time in the technical value table), directly mold the substrate with the thermoplastic elastomer. The time between adhesion promoter application and injection molding depends on process and environmental conditions as well as on the used thermoplastic elastomer and must be carefully evaluated. Any surface contamination must be avoided during the entire process. It is recommended to carry out tests for each new material or in case of material modifications.
