Dual Cure Adhesives

ACW’s Dual Cure Epoxy Adhesives can be cured with UV light or heat.  These are single component resins that offer long working lives at room temperature.  These products are especially good for active alignment applications.  Use UV to set the alignment and heat to cure the adhesive in shaded areas.  Thixotropic versions are available.  Thermal conductive versions are boron nitride filled.  For more details about Dual Cure Epoxy adhesives, see the Dual Cure page in the Blog section.  For a quick reference to popular Dual Cure Epoxies for active alignment applications, see the Dual Cure Table.
