Any ideas on polyurethane stuff? I've used Tiger Seal in the past, and it sticks/bonds like crazy. Sikaflex (221?) any good? This would be bonding metal to metal. Any other ideas?
you have just answered your own question , you said it works , so use it , it doesn t come any better for less than £12
I used sika resin 2 pack at Arsenal stadium to fix a couple of seats in the dug out into concrete,they stayed in place until the whole stadium was demolished
we used to stick our water bar keels on with sikaflex and beach our boats at 25 knots quite satisfactory .
Tiger seal is a 1 part pu, so is 221 Sika have a new hybrid PU/MS called AT. The MS part is the type stuff that Bostik/Evode marketed as Sticks Like S*** a few years ago when this technology became mainstream. MS generally has better temperature extremes performance than PU and is a bit more environmentally friendly (if that's a consideration)! I've not used the AT Metal product it but I will say when I was involved in the industrial adhesives industry, Sika had one of the best reputations for specialty bonding applications. If they've engineered the best characteristics of PU and MS polmers into one product, I'd personally give that a go @snotty http://www.diy.com/departments/sika...M6Gwod5PQDjQ&dclid=COHRyv23tM8CFUl62wodHjMKkQ
i have fixed the bay door strengtheners this week, with this masterseal from ebay , and they are stuck .. around £8 quid ..
We used to illustrate mechanical bonding by wetting glass slides & pushing them together. You can't get them apart so technically water bonds So it's not just about how it sticks now, but how it performs over time. I've done 'interesting' technical evaluation visits to customers with a warehouse full of perfect bound magazines waiting to go out to the news agents but can't because the pages were falling out. Residual solvents in the printing inks were attacking the glue line and because the bundles had been pallet wrapped off the lines, there was nowhere for the solvent to go! Work that out in the face of a multi £'000 claim..'coz the first people the binder wants to blame are the adhesive suppliers. "your glue's crap mate" This for panel bonding: 2 part epoxy. But look at the cost...
