BD Loops BD-LG2 2 Component Polyurethane Winter Grade Loop Sealant

Product Description:
BD-LG2 is a two-component polyurethane, detector loop sealant. It is designed for use in both asphalt and concrete pavement to provide a weather and chemical-resistant waterproof seal.

BD-LG2 Detector Loop Sealant exhibits exceptional chemical resistance to de-icing salts (including 50% by weight potassium acetate), gasoline, hydraulic brake fluid and motor oil. BD-LG2 requires no clean-up since the mixing tips are disposable.

Uses:
BD-LG2 is primarily used as a fast cure, protective seal for traffic detector wire loops employed in actuated intersections. It may be used as a sealant for saw cuts in concrete and asphalt surfaces.

Curing:
BD-LG2 will gel in only 8 - 15 minutes at 77°F (25°C). This product will take longer to gel at temperatures below 77°F (25°C). See the “Gel Time in Saw Cut” chart below. The cure will also depend on the volume of material applied. 

Superior Features:
BD-LG2 has no reaction with the asphalt and concrete and therefore will not deteriorate them. It exhibits no "bubbling" or "mushrooming". BD-LG2 will not expand or flow above the joint. Refer to Use and Handling Instructions. BD-LG2 is a 100% solids system, that contains no solvents and is zero V.O.C.
