Description
Single-component 98%-solids RTV silicone rubber. Room temperature cure (humidity-reactive). Completely noncorrosive. Forms tough rubbery coating. Excellent properties. Identical to 3140, except opaque gray coating of higher strength and toughness. Not self-leveling. Tear strength much higher than 3140.

Very thick, easy-to-apply, general-purpose coating can be applied without sag or runoff. Lab and field use. Good cable anchor. Low reinforcing effects. High-elongation capabilities. Good for short-term water immersion. Resists many chemicals. Bonds to contaminated surfaces for short term tests; for best long-term, chemically clean surface and prime with M-LINE RTV Primer No. 1.
