Master Bond's dual curing compounds cure both upon exposure to UV light and heat. These adhesives, sealants, and coatings are applied to assemblies where complete UV curing is difficult or impossible to achieve, such as applications with complex geometries and concealed areas. In applications with both optically opaque and transparent components, a dual cure system exhibits clear advantages over both UV and heat curable adhesives. It allows for curing in “shadowed out” areas at low temperatures. In surface mounting applications, a dual curing adhesive allows the manufacturer to fix the product in place with UV exposure and complete the bond with the addition of heat.
Master Bond Dual Curing Adhesives Provide Easy Application and Fast Curing
Master Bond offers one component dual curing adhesives that require no mixing whatsoever. The exposed areas of these compounds can cure in as little as a few seconds when UV light is applied, and the hidden areas cure in about 20 minutes upon exposure to heat. These cures are not inhibited by air and no solvents or vapors are released in the curing process. Master Bond's dual curing systems create strong bonds with metals, plastics, ceramics, glass, rubbers, and paper. Furthermore, special dual curing adhesives can cure in section thicknesses up to 1/4”.
