Product Recommendation

Creative Materials’ standard and custom formulations of potting compounds and encapsulants electrically insulate electronic and electrical components while providing protection from negative environmental conditions of high or low temperatures and chemical exposure. Our potting compounds and encapsulants are used for military, automotive, microelectronic, aerospace and industrial applications in power supplies, tachometers, wiring harnesses, cable assemblies, ignition coils and other electronics.

Our potting compounds and encapsulants feature low shrinkage, excellent adhesion and bond strength. Their cure temperatures range from room temperature to a mild heat cure, and available custom packaging options include cartridges, bulk packaging and syringes. Several of Creative Materials’ encapsulating materials are thermally conductive, resistant to thermal cycling and are useful for potting dissimilar materials.
