Re: Bond plastic to metal

Try this and let us all know!

http://miracleglue.com/

About 8 years ago or so I read an article in Model Railroader or RR Model Craftsman about a new glue that molecularly bonded anything to anything by penetrating the surface itself of both pieces. It was supposed to be for any material and it also was very expensive as there was a pre-treatment that had to be done to the areas to be bonded. Space age stuff... But, I don't believe I've ever seen it for sale since.

Re: Bond plastic to metal

THIS is the stuff I had read about:

http://www.tech-bond.net/Debonders_A...tors_Gels.html

I guess it's in wide distribution now. I'm going to try and find some and see how it works on (ulp!) John Deere's miracle hood material "Zenoy". The website has plenty of info on bonding different materials on the left side menu.

I wanted it now so I used a 2 part epoxy that is specially made for plastic. I'll let you know how it works. Thanks much for the info! Sounds like you may have bigger problems though. Cracked hood?

Re: Bond plastic to metal

Best glue for metal to plastic?
SEE this BLOG (3 pages of comments, to review): http://www.advrider.com/forums/showthread.php?t=120409

I've been using Gorilla Glue, on a few house projects & it is darn good stuff. http://www.gorillaglue.com/glues.aspx
Clean both dissimilar surfaces - works on many:
- slightly damp one side / just a little moisture helps, bond strength
- apply a thin film of glue on the other side (clamp surfaces or tape together) http://www.gorillaglue.com/glues/gorillaglue/index.aspx

The gorilla product fully cures in 24 hours, is waterproof - but the glue does expand upon drying and leaves a hard & dry milky colored residue / to scrape off later.
Shelf life is good so far, but should be stored cool....Keep away from Oxygen & Heat, to keep bottle fresh.
When I use it, I take a few drops out of the container, and quickly put the lid on.....Then I store it in the fridge, until next time.

It seems to have a Crazy-Super Glue (in gel or liquid) strength - as long as it's given the recommended full day to cure / plus a better shelf life.
(when I check my old tubes of 15 second drying GEL, contents are all hardened up / so I reach for the GORILLA stuff now...right from the kitchen fridge storage)

FYI
For duck tape - nothing I've found beats this, hands down: gorilla tape http://www.gorillaglue.com/tapes.aspx

Both the glue & tape products - from GORILLA, I'm honestly impressed with.

Good Gawd y'all, not yet! I just want to be the guy that finds the answer to all the JD cracked hood questions we see on MTF. The guy that does will get a virtual parade, free Lean Cuisine dinners for a year and a "sticky" named in his honor.

Re: Bond plastic to metal

There was a vendor at Cabin Fever selling a product like that, and he demo'd it for me. It seemed to work as claimed. The solvent for it is nitromethane.

When I worked for Malvese, they shot the ad for Eastman 910 adhesive for those of you who remember it, the one with the Ford tractor suspended from a crane. It was held up with a 2" diameter piece of bar stock that had been cut in half and glued back together.

Re: Bond plastic to metal

JUST SOME CRAZY / KRAZY trivia:
http://www.inventor-strategies.com/crazy-invention.html

Krazy Glue

This crazy invention bonded with anything it contacted. Harry Coover invented a glue while working for Eastman Kodak.

He was experimenting with various adhesives to make plastic lenses for rifle sights.

He created a substance that was impossible to work with because it stuck to everything.

It wasn't any good for making lenses but "cyanoacrylate" was an amazing glue. You could glue something instantly.

The bond was also very strong and permanent.


Other Uses

It was originally known as "Flash Glue" and then as "Eastman 910" adhesive. It was patented in 1958.

A cyanoacrylate spray was also developed and used during the Vietnam war to stop bleeding. A medical version of this spray is used in health care.
It was discovered that cyanocrylate could be used in forensics.

Fumes from the adhesive reacts with fingerprints and forms a white residue that reveals fingerprints on smooth surfaces.

These additional uses is a good example of how specific uses for an invention can be discovered after it has been patented.

Today, this popular and crazy invention is sold under the trade names "Krazy Glue" and "Super Glue".
