1. Product Overview

LOCTITE ECCOBOND LUX OGR150THTG is a single-component, UV and thermal-curable acrylate adhesive designed for high-throughput optoelectronic assembly. Key benefits include:

  • Fast UV cure with secondary thermal cure for shadowed areas
  • High glass transition temperature (Tg) for stability
  • Non-conductive and photocurable formulation
  • Low-temperature cure capability

Ideal for: Optoelectronic assembly where rapid curing and high-temperature resistance are required.


2. Applications

  • Bonding and assembly in optoelectronic devices
  • Applications requiring dual curing (UV and thermal)
  • High-volume industrial assembly
