OPTOLINQ LE-EP567D | Epoxy Resin for Bonding

Main features

  • High bonding strength
  • Excellent insulation
  • Good chemical resistance

Product Description

OPTOLINQ LE-EP567D is a two-component, low viscosity epoxy with excellent handling properties, chemical resistance, and high-gloss finish. It is ideal for potting, casting, sealing, encapsulation, and adhesive applications for composite materials, such as carbon fiber repair. 

The hardener of LE-EP567D does not form insoluble, white solids even after being exposed to air. The cured surface remains oil-free while maintaining excellent gloss retention. Additionally, OPTOLINQ LE-EP567D offers excellent electrical insulation properties under high humidity conditions, withstands exposure to a wide range of chemicals and solvents, and complies to RoHS 2011/65/EU Directive.

Applications

  • Carbon fiber bonding and composite repairs
  • Structural adhesive applications for metals, plastics, and composite materials
  • Potting, casting, and encapsulation for electronics
  • General-purpose sealing and bonding where durability and chemical resistance are needed
