Electric Motor Reliability with Huntsman ARALDITE® Encapsulation Potting – Casting
LOCTITE® 290™ is a low-viscosity, anaerobic threadlocker designed for locking and sealing threaded fasteners. Its capillary action allows it to wick between engaged threads without disassembly. It prevents loosening and leakage due to shock and vibration and can also be used to seal porosity in welds, castings, and powdered metal parts.
