https://www.mgchemicals.com/products/potting-compounds/epoxy-potting/electronic-potting-compound/

832HD is an electronic potting compound. It is a black, rigid, 2-part epoxy that provides extreme environmental, mechanical and physical protection for printed circuit boards and electronic assemblies.

Due to its low mixed viscosity, 832HD can easily penetrate small gaps and cavities. 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 epoxy has a convenient 1:1 volume mix ratio, making it compatible with most dispensing equipment. 832HD can be cured at room temperature or higher.
