1. Product Overview
LOCTITE ABLESTIK G 500HF is a one-component, heat-cured epoxy adhesive and sealant designed for assembly applications. It appears gray, is sag resistant, non-abrasive, and maintains adhesion even on vertical surfaces. The adhesive offers strong bonding at elevated temperatures, long shelf life at room temperature, and excellent resistance to heat and moisture. Its low halogen content (<1500 ppm Cl & Br) makes it suitable for sensitive electronic and industrial uses. Operating temperature ranges from -40 °C to +180 °C.
2. Applications
This adhesive is widely used in electrical and electronic assembly, especially for insulation and attaching leads to coils. It is compatible with substrates such as copper, ferrite, rigid plastics, and other metals. It is particularly suitable for general-purpose bonding where high adhesion and resistance to environmental factors are required.
