Shelf Life Details Scotchcast ™ 3570G Connector Sealing Packs must be stored at temperatures below 120°F., Scotchcast 3570G Connector Sealing Packs are usable for a period of one year from date of manufacture providing the Guard Bag (the white aluminized bag) is not opened when stored under the following recommended storage conditions: Store behind present stock in a clean dry place at a temperature of 70°F (21°C) and 40 to 50% relative humidity. Good stock rotation is also recommended. If the guard bag is removed the shelf life could be reduced under conditions of high humidity. For best results, use within one hour of opening guard bag. A Scotchcast 3570G Connector Sealing Pack is not impaired by freezing: however it should be warmed to at least 32°F (0°C) before being mixed or poured.

Best Practices for 3M 3570G
-
Surface Preparation
Thoroughly clean and dry the surface of the substrate to which the material is desired to bond.
-
Application
Remove guard bag, using caution not to damage inner bag.
Grip both edges of bag at the center barrier (FIG. 1) and wrinkle and flex the bag across the barrier. This will weaken the barrier.
Squeeze the clear side of the resin, forcing the resin through the center barrier.
Squeeze resin to one end of bag, and cut off other end.
Slowly insert connection into sealing pack until it fits snugly against the opposite end.
Wrap open end of bag with Scotch® Super 33+ Vinyl Electrical Tape and position the taped end up until resin gels.
-
Mixing
The resin must be mixed within the Unipak™ container simply by separating the barrier between the two parts of the bag and working the contents back and forth within the bag.
Mix thoroughly to a uniform color by squeezing contents back and forth 25-30 times.
