LOCTITE ECCOBOND LUX A4021T is a single-pack, photocurable acrylate adhesive designed for high-performance optical and optoelectronic applications. It features a high refractive index, low shrinkage, and excellent adhesion to glass and steel. The adhesive cures rapidly under UV (365 nm) or visible light (470 nm) and has a secondary thermal cure option for shadowed areas. It is formulated to enhance productivity in fiber optics and optoelectronic device assembly.
LOCTITE ECCOBOND LUX A4021T is widely used in the optoelectronics and photonics industry for:
