Loop Sealant Tube 30 Fluid Ounces
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 seal.
Q-Seal 290S is primarily 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. 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.
The substrate should be dry, dust free and as smooth as possible before installation of Q-Seal 290S. It is recommended that ambient temperatures at time of sealant application should not exceed 100°F or fall below 36°F. It is recommended that Q-Seal 290S be applied by using a pressurized dispensing system, allowing for positive injection of Q-Seal 290S into the saw cut to properly encapsulate the loop wire. Normally the dispensing system consists of a 10:1 ratio pump with air regulator, gauge and air valves. The primer is an elevator with a follower plate that should be resistant to aromatic hydrocarbons. The hoses used should be Teflon lined with stainless steel cover. The flow gun itself should be a 6000 psi extrusion flow gun with various wand attachments. To apply the 30 fl. oz. cartridge, use a manual or air-operated caulking gun.
Q-Seal 290S Grey or Black is available in 30 fl. oz. cartridges. Shelf Life is 1 year from date of manufacture.
Use Chemque solvent S-235. Caution: Clean equipment after use. Use Chemque Q-CLEAN to remove sealant from your hands.
