Master Bond’s dual curing compounds cure both upon exposure to UV light and upon exposure to heat. These adhesives, sealants and coatings are applied to assemblies where complete UV curing is either too difficult or impossible to achieve, such as applications with complex geometries and concealed, “shadowed out” areas.
Master Bond Cationic and Free Radical Dual Cure Systems
Master Bond’s extensive line of dual cure systems includes products with many different chemistries, including:
- Epoxy acrylates
- Urethane acrylates
- Polyester alloys
Easy Curing Process of Master Bond’s Dual Curing Adhesives
These products offer easy application and incredibly fast cures. The exposed areas of dual curing adhesives can cure in a few seconds when UV light is applied and the hidden areas cure in about 20 minutes upon exposure to heat. These systems are not inhibited by air and no solvents or vapors are released during the curing process.
Most Popular Dual Curing Adhesives, Sealants and Coatings
- Dual cure UV system with a secondary heat cure mechanism (250°F) for “shadowed out” areas (those not available to the UV light source). Optically clear and non-yellowing. Produces tough, durable bonds.
- High viscosity, UV and/or heat curable modified epoxy resin for high performance bonding, coating and casting. Serviceable from -60°F to +300°F.
- UV and heat curable epoxy system for high performance bonding, coating and sealing. Dual cure system allows for curing in “shadowed out” areas at temperatures as low as 80°C. Passes 1,000 hours at 85°C/85% humidity. Shore D hardnes >70.
