Polyurethane and superglue are completely different compounds, so it's hard to imagine merging the two into one product, IMO. "Superglues" are cyanoacrylate glues a different chemical family to the polyurethanes - they are basically acrylic resins - although they, too require the hydroxyl ions in water to cure in the same way that 1-component PUR (polyurethane) glues do. Heat reactivated PU glues such as edge banding hot melt, etc. seem to react very little if at all to water.
Beware of cyanoacrylate glues as most contain ethyl or methyl alcohol, either of which is toxic (not to mention highly flamable), but if you ever do manage to glue your fingers together, acetone nail-polish remover will generally undo the damage (so you need to rob the wife's dressing table before using it, just in case :lol: ). For that matter 1-part PU glues are NOT UV proof (sunlight - ever seen the results of expanding building foams exposed to sunlight for a few years) and uncured adhesive is a known carcinogen (PUR contains Diphenylmethan-4,4'-diiosocyanate according to the COSHH sheets). It is best to wear disposable gloves when handling PU glues as the black hardened skin resulting from skin contact can take days to scrub off with a pumice stone (meths works if you are VERY quick, so if anyone knows a non-toxic alternative, I'd be glad to hear from them). So, be careful with either of them.
Had to do the techie bit on this as part of my Safety and Hazard Assessment :?
Byron - Personally I don't see the point in buying Titebond aliphatic resin - aliphatic resin is just another name for polyvinyl acetate - or if you want to be basic, it's fundamentally a starch. There are plenty of firms making PVAs in the UK and EU so where's the environmental "advantage" to shipping it across the Atlantic? If you want a PVA which sets permamently, is waterproof and doesn't creep, simply look for one which is type D3. Similarly Gorilla glue is actually made in Denmark (or was the last time I looked at a bottle) and has probably done a lot of travelling by the time it gets here (via the USofA). Greenie rant over :lol:
