Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Welcome to TECHNIQ VIET NAM
LOCTITE ECCOBOND LUX OGR150THTG is a high-Tg, non-conductive, photocurable adhesive based on acrylate technology. It is designed for high-throughput optoelectronic assembly operations. The adhesive cures rapidly under ultraviolet (UV) light and has a secondary thermal cure mechanism for shadowed areas. This single-component adhesive provides excellent mechanical strength, high refractive index stability, and low moisture absorption.
