Product Description
Traffic Detector Loop Sealant
Q-SEAL 290S Detector Loop Sealant is a one component thixotropic moisture curing polyurethane sealant. It is designed for use in both asphalt and concrete pavement to provide a weather and chemical resistant waterproof seal.
Q-Seal 290S is used as a protective seal for traffic detector wire loops employed in actuated intersections. It may be used as a sealant for saw cuts in concrete or asphalt surfaces.
Q-Seal 290S will skin over in approximately 3 hours at 77°F and 50% R.H.= (Relative Humidity). At temperatures below 77°F this product will take proportionately longer time to cure. At temperatures above 77°F it will take a proportionately shorter time to cure.
Surface Preparation: Remove standing water. The substrate should be dust free and as smooth as possible before installation of Q-Seal 290S. It is recommended that surface temperatures at time of sealant application should not exceed 100°F nor fall below 35°F.
