MOMENTIVE PERFORMANCE MATERIALS RTV133 silicone rubber sealant

The RTV 133 is a black, one-component, ready-to-use silicone rubber adhesive sealant. It is designed for applications in electronics, appliances, transportation, and other industries where flame resistance is critical. This sealant cures upon exposure to atmospheric moisture at room temperature, forming a tough, durable, and resilient silicone rubber. It releases alcohol vapor during curing, resulting in a low odor process with minimal unpleasant smell or fumes. The RTV 133 offers excellent resistance to high temperatures, weathering, ozone, and chemicals, along with good electrical insulation properties. It also exhibits flexibility at low temperatures, self-adhesion, and is non-halogen with flame retardant ratings of UL-94 V-0 or V-1.
