MG Chemicals 832B-450ML Black Epoxy Potting Compound for Electronics

832B is a general-purpose, rigid, 2-part black epoxy potting compound. Once cured, it provides extreme environmental and physical protection for printed circuit boards and electronics, and its rich black color keeps intellectual property secure and tamper-proof. It's ideal for projects needing basic protection in harsh climates — the tough finish shields components from shock and impacts while extending circuit lifespan. The mixed liquid is thin, so it spreads well and covers small parts easily, and it bonds well to most surfaces without corroding copper.

MG Chemicals 832B-450ML Black Epoxy Highlights:
