1. Product Overview

LOCTITE ECCOBOND LUX 3042M is a one-component, dual-cure acrylate adhesive designed for assembling temperature-sensitive electronic components. It initially cures under ultraviolet (UV) and visible light and achieves maximum performance through a secondary thermal cure. The product offers strong adhesion to various substrates and is non-conductive.

2. Applications

  • Used for bonding temperature-sensitive electronic components
  • Suitable for assembly applications requiring a dual-cure system
  • Ensures strong adhesion with non-conductive properties
