Activator-Cure Structural Adhesive

846-GEL structural adhesive utilizes activator to form excellent high-strength bonds to a variety of metal surfaces, glass, ceramics, filled nylon, thermoset plastics, and epoxy board. The product is ideal for applications where dissimilar substrates are to be joined and maximum tensile shear strength is required. The adhesive cures upon contact with Dymax solvent-free activators between closely mating surfaces, or upon application of heat. The material doesn’t cure until assembly allows time for precise alignment of parts. 846-GEL is also good for magnet bonding.

Dymax materials are solvent free and cure upon exposure to light. Their ability to cure in seconds results in lower processing costs. When cured with Dymax UV light curing spot lamps, focused beam lamps, flood lamps, or conveyor systems they deliver optimum speed and performance for maximum efficiency. Dymax lamps offer the optimum balance of UV and visible light for the fastest, deepest cures. 846-GEL is in full compliance with RoHS2 Directives 2015/863/EU.
