Dymax OP-83-LS Low Shrinkage Epoxy, Off White Opaque to Charcoal Translucent Gel, Hybrid UV, LED & Heat Cure - 10ml Syringe

The Dymax OP-83-LS Low-Shrink™ Hybrid UV & Heat Cure Epoxy is a fast-curing, low-shrinkage UV/Visible light-curable epoxy designed for superior adhesion, particularly in camera modules. This epoxy is formulated to cure primarily with UV light but also features a low-temperature heat-curing (80-85°C) option, making it ideal for applications with shadow areas or where heat-only curing is preferred. The rapid curing time of OP-83-LS facilitates faster processing, increases output, and reduces overall processing costs.

This Dymax UV curing epoxy product is also compliant with RoHS standards, aligning seamlessly with directives 2015/863/EU for environmental responsibility. Epoxy is packaged in a 10ml syringe.
