1. Product Overview

LOCTITE ECCOBOND EN 190024FL is a one-component, fluorescent acrylate adhesive with a translucent light blue appearance. It cures rapidly under UV and visible light, making it suitable for high-throughput production lines. The material is designed to enhance load-bearing and shock-absorbing properties, while also enabling easy in-line inspection thanks to its fluorescent characteristic. It is recommended for bonding rigid and flexible PVC to polycarbonate where flexible joints and gap filling up to 0.25 mm are required.


2. Applications

  • Encapsulation, glob top, and general electronic encapsulation.

  • Bonding glass, plastics, and most metals.

  • Specially effective for rigid and flexible PVC to polycarbonate assemblies.

  • Used where enhanced toughness, flexibility, and optical inspection are essential.
