Momentive RTV12A-1G Low Viscosity Dual-Component Silicone Potting Base Compound, Clear, 1 Gallon Pail

RTV12C curing agent is mixed with RTV12A base compound producing a clear cured rubber to provide see-through properties in greater thicknesses. RTV12 allows visual observation of the components during pouring and easy identification, repair, and replacement of components when necessary.

RTV12 is suggested for evaluation as a potting material to provide environmental protection to electrical and electronic assemblies. When cured, the soft, rubbery property of RTV12 rubber cushions against mechanical shock and vibration. The excellent electrical properties make it a candidate material for both high and low
voltage electrical assemblies.
