3 M™ D e t e c t o r Loop Sealant…easy to use…superior p ro t e c t i o n

Saves application time3M loop sealant is ready to use. T h e r eis no need to measure, mix or heat andno smoothing is required. Sealant canbe applied on crowned or slopedroadways. It will not run to low spots.

Outstanding pro t e c t i o nLoop wires are held in position andcompletely contained in a tough, yetflexible, rubber cocoon. Wires areprotected against movement, roaddebris penetration and moisture,eliminating these causes of false calls.

Reduced maintenance3M sealant will not shrink, so call-backs for refilling are eliminated.And sharp objects will not penetratethe tough rubber. Sealant cures withsmooth surface so there is no need for finishing.

Natural curingSealant reacts with moisture in theenvironment to produce a rubber thatis resistant to weather, oils, gasoline,antifreeze, brake fluid and road salt.

Long lastingThe sealant will not become brittlewith age or temperature extremes.

Te m p e r a t u re stableThe sealant won’t degrade in hightemperatures or fracture at tempera-tures as low as -4 0 ̊ F.

Roadway compatibility3M sealant can be used with eitherconcrete or asphalt, fresh or aged, wet or dry surfaces.

Fast, complete application3M supplies special nozzles that help you fill the sawcut from thebottom to the top.

N e w, more convenient application3 M ’s new ply pack is especially wellsuited for customers who use applica-tor guns to apply sealant. Dispensingrate is improved by up to 300%.Disposable packaging waste is r e d u c e dby over 90% at the work site.

3M detector loop sealant encapsulates,insulates and protects the wires of adetector loop from the effects of theharsh roadway environment. In tempera-ture extremes, it retains flexibility so thewires are continuously protected toprevent loop failure.

Some good reasons you should be using 3M detector loop sealant:
