LOCTITE ECCOBOND LUX OGR150THTG – Adhesive – Optoelectronic Assembly

  • Item Name: LOCTITE ECCOBOND LUX OGR150THTG
  • Manufacturer: Henkel
  • Technologies: Acrylate
  • Color: Colorless
  • Cure Type: Ultraviolet (UV) light, secondary thermal cure
  • Package Size: Contact to Techniq VN for details.
  • Shelf Life: 6 months

1. Product Overview

LOCTITE ECCOBOND LUX OGR150THTG is a high-Tg, non-conductive, photocurable adhesive based on acrylate technology. It is designed for high-throughput optoelectronic assembly operations. The adhesive cures rapidly under ultraviolet (UV) light and has a secondary thermal cure mechanism for shadowed areas. This single-component adhesive provides excellent mechanical strength, high refractive index stability, and low moisture absorption.

2. Applications

  • Optoelectronic assembly
  • Bonding applications requiring high strength and rapid cure
  • Assemblies with shadowed areas needing secondary thermal cure
