We formulated our 3M Detector Loop Sealant 5000 specifically for protecting detector loop wires even in challenging roadway environments. We also designed this sealant to be extremely easy and cost-effective, both during and long after application.
Tough Yet Flexible
The sealant can be applied directly into the sawcut to form a durable tack free shell around detector loop wires without running into low spots, even on crowned or sloped roadways. It cures naturally in 24 hours, reacting with moisture in the environment to produce a rubber that resists weather, oils, gasoline, antifreeze, brake fluid and road salt. This tough, flexible material also prevents the wires from moving around as it keeps contaminants away from them, minimizing false calls.
The cured sealant presents a smooth surface across the sawcut so workers do not have to spend extra time finishing. It won’t degrade in high temperatures, fracture even at temperatures as low as -40° F, or shrink over time; this eliminates call-backs for refilling or additional repairs.
