Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Welcome to TECHNIQ VIET NAM
LOCTITE ECCOBOND LUX OGRFI146T is a single-component, photocurable adhesive specifically designed for optical, fiber optic, and optoelectronic device assembly. This acrylate-based adhesive offers a low refractive index, making it ideal for high-precision optical applications. It cures rapidly under UV or visible light and also features a secondary thermal cure mechanism for shadowed areas where light cannot penetrate. The product is designed for bonding silicon and ceramics and ensures high productivity in assembly processes.
