LOCTITE® ABLESTIK 8387B
Features and Benefits
A black non-conductive adhesive 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 100ºC (212ºF). If cured properly, it should pass the NASA outgassing standards.
