By getting the SKU (267011) off the web and bringing it to a store I finally managed to get hold of a roll of the Nashua silicone sealing tape from Home Depot. Ten foot roll costs $6.77, color your choice of black. I think price for price they're probably similar value, but I'm not sure that the Nashua stuff would be as satisfactory. I think it would, but I'm not sure. It would need more layers to get the same effect. It would certainly be much easier to apply for people who have trouble getting enough stretch on the Rescue Tape. The instructions on the package are very poor; they don't even mention stretching it, let alone emphasize it; and they don't talk about curing time. The Rescue Tape in stretched and then relaxed condition is about .022" constant thickness. The Nashua tape under same condition is about .020 in the middle half, tapering to .010 at each edge. Based on a short sample, weight ratio for equal lengths is about 9:7 but could be almost 10:6. Willing stretch is about the same, call it 3:1. Each will fuse to the other no problem. From a never-stretched condition the Nashua will run out of stretch before the Rescue Tape has stretched more than a few per cent. Once the Rescue Tape is fully stretched and relaxed, the Nashua tape will stretch about two or more to its one. I haven't set up a clamp and spring scale yet, but by pulling apart between two hands (remember, I'm sixty) I was barely able to break the Nashua tape and got my fingers bit for my trouble. I could not break the Rescue Tape. I'm certain I can exert at least fifteen pounds that way and probably twenty five. Yours, David -- David Beierl -- dbeierl@attglobal.net |
