G/flex is a separate epoxy system from 105 Resin and its 200-series hardeners. Follow the G/flex instructions for mixing and substrate preparation. Plastic adhesion varies with the plastic type; check the preparation method and test adhesion instead of assuming compatibility with every plastic.
The liquid formulation can wet out fiberglass tape and can be modified with appropriate WEST SYSTEM fillers. Select the thickened 655 adhesive when a non-sag paste is needed.
