Bonding Guidelines – Please refer to PMC bonding video for further instruction.

Our CFRT^® materials can be In-Molded, Stock-Fit and Injection Over-molded. The following are our bonding guidelines.

Bonding requires that the surface be cleaned, but not dissolved too aggressively, as the polymer can be removed exposing the fibers. Cleaners such as isopropyl alcohol, IPA, are preferred over aggressive solvents such as MEK. The surface of the material and adhesive layers should be free from contaminants such as mold release, oil from fingers in handling, etc. The content of aggressive solvents in primer and adhesives should be minimized where possible.

Excessive wiping, brushing or pooling of cleaners, primers and adhesives should be avoided.

Priming

- Apply a thin layer of the primer with a clean brush with a light back and forth stroke.

- Heat the material with primer at 50°C – 60°C for 2-3 minutes in a convection oven.

Adhesive Application

- Apply a thin layer of the adhesive with a clean brush with a light back and forth stroke.

- Heat the material with adhesive at 50°C – 60°C for 2-3 minutes in a convection oven.

Exposure to high temperature radiant heating elements should be avoided as the thermoplastic material can lose shape.

Attach the plate with adhesive to the other properly prepared component (e.g. – outsole) by applying uniform pressure over the entire surface.
