A tough, rubbery solid when exposed to moisture in the air. Since it will not flow under its own weight, it can be applied on sidewall joints and surfaces or overhead without sagging, slumping or running off. It will adhere to clean metal, most types of non-oily wood, vulcanized silicone rubber, silicone resins, natural and synthetic fibers, ceramic, paper, as well as many painted and plastic surfaces.

Resistance to Temperatures Extremes-LMS100 Hi-Temp Red RTV 100% Silicone adhesive/sealant offers both extreme low and high temperature resistance properties. It remains flexible to -70 deg F and although modulus increases, it does not become brittle. This product will also withstand high temperatures up to 500 deg F for short periods.

Weatherability-Hi-Temp RTV adhesive/sealant remains flexible to extreme temperatures. Because this material is 100% solid and contains no extenders or plasticizers, shrinkage due to weathering is negligible. Because of the chemical makeup, resistance to ultraviolet light and ozone is excellent.

Maintenance-If Hi-Temp Red RTV silicone sealant becomes damaged, replace damaged portion. Clean surfaces in damaged area, remove any residual sealant, and repair with fresh silicone sealant.

Chemical Resistance-LMS100 Hi-Temp Red RTV adhesive/sealant offers good resistance to most solvents and oils, organic and inorganic chemicals; however, it is not recommended for continuous use with gasoline or fuel oil. Swell or degradation may occur with these and certain other hydrocarbon materials. Chemical compatibility should be tested for each application considered.

To weatherproof, protect, and insulate:
Make tractor and truck cabs leakproof, fill slots in lathe collets, insulate wires carrying high voltage, seal & waterproof cable connectors, motors, switches, windings and cover plates, repair or replace inadequate insulation between electrical contracts to prevent arching, use as potting compound for electric power supplies, strobes and lamps, seal holes where electrical wires run through walls, seal areas subjected to moisture, hot cooking oils and free steam

To control noise and vibration:
Use under motor mounts and on nuts and bolts to absorb vibration, seal fasteners against vibrations, dampen speaker vibration, make noise dampening pads, use to pot components on circuit boards to protect them from vibration, protect glass meter covers from vibration, seal the vibrator mechanism of electrostatic precipitators

Applying the Materials: Tack-Free Time:
LMS100 Blue RTV adhesive/sealant is supplied ready-to-use. The cure progresses inward from the surface. At conditions of at least 75 deg F(24 deg C) and 50% relative humidity, the sealant forms a tack-free skin within 20 minutes. Tooling is not practical after this skin begins forming, and should be completed within 5 to 10 minutes of application, even though this may require alternate periods of applying and tooling. If masking tape has been used to mark off an area, it should also be removed before the skin forms. Cure time is affected by relative humidity, degree of confinement, and cross-sectional thickness of the sealant. Sections up to 1/8 inch thick become rubbery solids in about 24 hours at room temperature at 20% relative humidity. Less moisture content reduces it slightly. In 72 hours, sections up to 1/8 inch thick cure to a rubber with a Shore A of 30.

LMS100 SEALANTS ARE DESIGNED TO MEET THE FOLLOWING SPECIFICATIONS:
