Urethane Potting Compounds

MG Chemicals polyurethane resins provide cost-effective alternatives to other chemistries for protecting printed circuit boards and electronic devices. These 2-part potting compounds are especially suitable where low temperature flexibility is required. They have been formulated in convenient 2:1 mix ratios and provide strong protection from moisture, sea water, solvents, and mechanical stress. They are an ideal potting compound for underwater applications.
