Loctite 840057 Clear 40994 435 Prism Instant Adhesive, 20 mL Bottle

I had two very specific manufacturing requirements. High tensile strength with good shock performance. This blend of cyanoacrylate adhesive fulfilled my requirements completely.

its not instant its for your fingers they stick instantly on contact

The best "superglue" cyanoacrylate I have ever used. Had a bottle in my refrigerator for 15 years. Bought it for a job for job for a client and then used it for projects as they came up over the years. Wasn't until my son got old enough to start using it that it got left out with the applicator tip left unwiped. Time to buy another bottle.
