A clear, two component, low viscosity potting compound that cures at room temperature to a soft pliable rubber. Will cure in deep sections. Designed to acheive primerless adhesion to many substrates, including metals, plastics, and ceramics. The excellent electrical properties make it a candidate material for both high and low voltage electrical assemblies. Cushions against mechanical shock and vibration. RTV12 is clear enough to allow visual observation of components during pouring. After cure, the clarity lends to easy identification, repair and replacement of components.
