MG Chemicals 832B - Black Epoxy
- Chemical Family
- Epoxy & Epoxy Derivatives
Black Epoxy, Encapsulating & Potting Compound 832B is a general purpose, rigid, 2-part black epoxy that provides extreme environmental, mechanical and physical protection for printed circuit boards and electronic assemblies. Due to its low mixed viscosity, 832B 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.
