Description
Chem-Set 412 Clear Electronic and LED Potting Silicone is a low-viscosity, self-leveling, two-component, addition-cure silicone elastomer that will cure at room temperature or at elevated temperatures. Available in easy-to-use cartridges that require no hand-mixing the ChemSet 412 is ideal for LED light potting and applications that require clarity. ChemSet 412 has a low viscosity, which allows for ease of flow around complex parts, providing electrical insulation, clarity, and shock resistance.
