1. Product Overview

LOCTITE® HHD 8180BK is a two-component, room-temperature curable methacrylate adhesive. Part A is a black liquid, Part B is a white liquid, and when mixed, it forms a black adhesive. It offers low viscosity, color matching capability, and high bond strength. The adhesive is self-leveling and formulated to form resilient bonds that maintain strength across a wide temperature range, making it suitable for structural bonding in electronic assemblies.


2. Applications

  • Structural bonding of plastics, metals, or dissimilar materials

  • Electronic device assembly requiring resistance to vibration and impact

  • Use in portable electronic devices

  • Suitable for volumetric or cartridge/static nozzle mixing
