MG 832HD is an economical, flowable, electronic-grade black epoxy that is said to provide excellent physical, chemical, and electrical protection. It features a very hard shell, providing a high degree of protection against extreme impacts and vibrations and is available in dual cartridge format.

MG 832FX is a flexible black epoxy encapsulating and potting compound. It forms a tough bond that flexes to provide impact and vibration resistance and offers excellent physical, chemical, and electrical protection. This epoxy is said to be particularly effective where severe thermal shocks occur in the components' environment or where devices are in a submersion state.

Being black in colour means that they help to hide and restrict access to intellectual property and protect proprietary electrical circuit designs.
