LOCTITE® ABLESTIK 8387B
Features and Benefits
This black non-conductive adhesive is designed for optoelectronic devices in aerospace and defence devices.
LOCTITE® ABLESTIK 8387B is a black, non-conductive epoxy adhesive for high-throughput die-attach applications. It’s particularly used for glass attachment to optical and 3D sensors in aerospace and defence applications. It cures fast when exposed to direct heat energy or hot-plate techniques. In conventional box- or convection conveyor oven curing, it will cure at temperatures as low as 100°C (212°F). If cured properly, it should pass the NASA outgassing standards.
- Fast-curing
- Good adhesion to glass
- Jettable
- Non-conductive
