Protective Coating
FEATURES
• Easy to use
• Good mechanical protection
• Good cable anchor
• Room-temperature cure
DESCRIPTION
Single-component 98%-solids RTV silicone rubber. Room
temperature cure (humidity-reactive). Completely non-cor-
rosive. Forms tough, rubbery coating. Excellent properties.
Opaque gray coating of higher strength and toughness than
3140 RTV. Not self-leveling.
Easy-to-apply general-purpose coating. Lab and field use.
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 protection, chemically clean surface and prime
with M-LINE RTV Primer No. 1. Very thick coatings can be
applied without sag or runoff. Tear strength much higher than
3140. Good cable anchor.
