Dymax OP-81-LS Hybrid UV & Heat Cure Adhesive (10ml)

The Dymax Low-Shrink™ OP-81-LS Hybrid UV & Heat Cure Adhesive is a UV/Visible light-curable epoxy featuring very low volumetric shrinkage during cure and low CTE for stability through thermal excursions making it ideal for rapid positioning of optical components. OP-81-LS is specially formulated to cure primarily with UV light and includes a low-temperature heat-curing function in applications where shadow areas exist or where heat cure only is preferred. Packaged in a 10ml adhesive syringe, this Dymax product is also compliant with RoHS standards, aligning seamlessly with directives 2015/863/EU for environmental responsibility.
