832B - Black Epoxy

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.

This black epoxy potting compound has a convenient 2:1 volume mix ratio, making it compatible with most dispensing equipment. 832B can be cured at room temperature or higher.

For a 1:1 mix ratio consider 832HD. For clear 2-part epoxies try 832C or 832WC. We also offer flexible, thermal and high temperature epoxy potting compounds.

Our 2-part flame-retardant epoxy potting compounds are 834B, 834HTC and 834FX.

For a 1-part epoxy try 9510.

We also offer polyurethane and silicone potting compounds.
