LOCTITE ECCOBOND EN 3710F is a yellowish opaque, acrylic-based adhesive designed for fast and reliable encapsulation and bonding of electronic components. It is a low modulus material with excellent flexibility, fluoresces under UV light, and cures rapidly when exposed to suitable UV light. Additionally, it incorporates a secondary heat cure system for applications involving shadowed areas, ensuring complete and durable adhesion.
Encapsulation and glob top protection for PCB components
Bonding electronic parts where rapid UV cure is required
Ideal for assemblies with shadowed regions needing secondary thermal cure
