- Description
- Technical specification
LOCTITE® STYCAST U 2500 HTR flexible polyurethane encapsulant is specially formulated to have low viscosity and excellent wetting properties for complete impregnation of both small slightly wound coils and large castings. It can also be used to replace silicones. LOCTITE STYCAST U 2500 HTR has a higher service temperature than standard polyurethane materials and is ideal for transformers, PCBs and other insulating applications.
