Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
Welcome to TECHNIQ VIET NAM
Loctite® EA 3430 is a two-component, ultra-clear epoxy adhesive designed for rapid curing at room temperature. It provides high bond strength on a variety of substrates, including metal, ceramic, rigid plastics, and wood. Its gap-filling properties make it ideal for bonding rough or poorly fitting surfaces.
