834B is a black, rigid, flame-retardant thermal potting compound that offers extreme environmental, mechanical and physical protection for printed circuit boards and electronic assemblies.
This 2-part epoxy is designed for applications where thermal management and self-extinguishing are critical. It also provides excellent electrical insulation and protects components from static discharge, vibration, abrasion, thermal shock, environmental humidity, salt water, fungus, and many harsh chemicals.
This high thermal conductivity potting compound has a convenient 2:1 volume mix ratio, making it compatible with most dispensing equipment. 834B can be cured at room temperature or higher.
for a low CTE version try 834HTC and for a flexible version use 834FX.
