Safety Data

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 inductance loops installed in saw-cut slots. It may be used as a sealant for saw cut slots in concrete and asphalt surfaces.

Dispensing Gun

BD-LG2 is packaged in a 600ml dual cylinder cartridge (300ml:300ml). It requires a compatible dual cartridge dispensing gun to use.

We offer a high quality dripless dispensing gun: BD-LG2-GUN.

Curing

BD-LG2’s Gel Time is as follows:

Gel Time in Saw-cut Slot*

Temperature**BD-LG2 Gel Time
23°F (-5°C)120 Minutes
41°F (5°C)45 Minutes
59°F (15°C)15 Minutes
Over 59°F (15°C)Less than 15 Minutes
*1″ deep x 1/4″ wide slot
**Temperature of material and substrate

For loop applications, the tack free time is not critical for opening the lanes for traffic if saw cut slot is filled 1/8 inch below pavement/concrete surface. Also, if BD-LG2 is kept at a warmer temperature, (i.e. placed in truck cabin while heater is on) the cure time in saw cut slot will decrease.

FAQ

If groove is slightly underfilled (1/8″) traffic is permitted immediately after application. Slightly underfilling the groove is the ideal application method, it looks clean and keeps tires out of the sealant.

BD-LG2 will fully cure in 15 minutes or less if the ambient temperature is above 60° F.

The groove should be clean and dry (free of dust, water and ice) before applying BD-LG2. If the substrate is not dry or if it is coated with a thin layer of ice, the surface may be heated with a torch or hot air gun to dry.

BD-LG2 is a polyurethane loop sealant – which means it should not come in contact with water while curing. If BD-LG2 comes in contact with water off-gassing may occur which will result in air bubbles in the seal.

Our new single part loop sealant BD-LS high tech compound that doesn’t have an issue with water while curing – in fact it can cure underwater. However, BD-LS should not be applied in freezing temperatures.

1 year shelf life from date of manufacture. The manufacture date can be found printed on a sticker on the foil pouch. It can also be found on a sticker on each sealant case.

For maximum shelf life store in a dry, cool, and well-ventilated place.

BD-LG2 will cure in below freezing temperatures. The colder it is the longer it takes to cure, but unlike other loop sealants it will cure.

BD-LG2 can be used at even lower temperatures, it will just take longer to cure. For reference BD-LG2 has been used in in below 0° F freezer warehouses and installed in the Arctic tundra.
