BD Loops Loop Goop - Polyurethane Saw-Cut Loop Sealant

Note: Tubes have been redesigned and currently feature tips that do not fit into the crack. Tubes do not work with caps that were supplied with old stock. See the New Tip Design.

BD Loop Goop is a tough and durable polyurethane resin sealant designed to encapsulate, protect and insulate inductance loops for door, gate, and parking applications. Effectively seals out moisture and provides exceptional chemical resistance to de-icing salts, antifreeze, gasoline, motor oil, hydraulic brake fluid and other hydrocarbons. BD Loop Goop remains strong, flexible and resilient in cold weather. It provides superior adhesion to wires and saw cuts in concrete and asphalt. Application does not require mixing or heating. Permits vehicular traffic immediately after application with no need for lane closure. DOT APPROVED by most States. To get the most out of your tube of Loop Goop use with a 3/16" wide saw blade, and 3/16" Preformed Saw-Cut Loops. There is a minimum order of two cartridges.

SURFACE PREPARATION: Wash and blow out saw cuts with compressed air (such as the BD Loops Air Wand) to remove dust, debris and standing water. It is recommended that ambient temperatures at the time of sealant application should not exceed 100°F (38°C) nor fall below 36°F (2°C). Do not apply to wet or icy surfaces. Curing time will be lengthened below 36°F (2°C) and shorted above 100°F (38°C).
APPLICATION: Cut the tip of the Loop Goop cartridge using a safe tool. Tightly screw the disposable threaded nozzle in place and insert the cartridge into the caulking gun. Apply sealant from the bottom of the saw cut to within 1/8" (3.12 mm) of the roadway surface. Pneumatic and battery powered dispensing guns are available.
CURING: Will skin over in approximately 3 hours at 77°F (25°C) and 50% R.H. Hotter, more humid weather speeds up curing; cooler, dryer weather slows it down. Full cure will take several days, however traffic is permitted immediately after application.
CLEANUP: For product handling and clean-up wear disposable latex gloves, rubbing alcohol helps clean up spills. If you are unsure if rubbing alcohol can be used on a surface/finish, first test clean a small inconspicuous area to see if damage occurs.
STORAGE: For maximum shelf life, store in a dry, cool place.
NOTES: Loop Goop Loop Sealant exhibits exceptional chemical resistance to the following chemicals:

• De-icing salts
• Gasoline
• Hydraulic Brake Fluid
• Motor Oil
• Sodium Chloride (5%)

SAFETY & HANDLING: Keep away from heat and open flames. Use only in well ventilated areas. Do not breath vapors. In case of contact, immediately flush eyes or skin with plenty of water for at lest ten minutes. If contact is made with eyes, get immediate medical attention.
