CALL NOW TO ORDER: (520) 303-4444

One tube may seal 9-15 feet of cut, depending upon actual conditions. Always purchase an extra tube or two to make sure that you have enough!

Q-Seal 290 Detector Loop Sealant is a one component thixotropic (thickened, like paste) moisture curing polyurethane sealant. It is designed for use in both asphalt and concrete pavement to provide a weather and chemical resistant waterproof seal. This product requires no catalyst. Detector Loop Sealant

USES


Q-Seal 290 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. Use of this sealant may help to reduce the effects of weather upon the disturbance of the cut made into the roadway surface.

CURING


Q-Seal 290 will begin to dry ‘skin over’ in approximately 3 hours at 77F and 50% R.H. At temperatures below 77F this product will take a proportionately longer time to cure. At temperatures above 77F it will take a proportionately shorter time to cure.

SURFACE PREPARATION


The roadway should be dry, dust free and as smooth as possible before installation of Q-Seal 290. It is recommended that air and roadway temperatures at time of sealant application should not exceed 100F or fall below 36F. It is recommended that Q-Seal 290 be applied by using a pressurized dispensing system, allowing for positive injection of Q-Seal 290 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. We can supply the caulking gun as well.


PACKAGING


Q-Seal 290 is available in Grey or Black, in 5 gallon pails and 30 fl. oz. cartridges.
Shelf Life is 1 year from date of manufacture.


CLEAN UP


Use Chemque solvent S-235. Caution: Clean equipment after use. Use Chemque Q-CLEAN to remove sealant from your hands.
