What is the World’s Strongest Adhesive?

Many people might think of the brand names Super GlueTM or Krazy GlueTM as the strongest glue in the world. Those glues are actually a class or type of adhesives called cyanoacrylates, also known as instant glues. Remember that commercial of a man dangling from a metal bar with his hard hat attached to it? If you’re looking for glue in a strength-to-volume perspective, then cyanoacrylates probably do supply the strongest bond and they are very resistant to most chemicals, water and mild heat. However, they are not flexible so any amount of bending, expanding or contracting, they become brittle and break.

Others may think its two-part epoxies because they are strong, flexible, waterproof and resistant to heat, cold and chemical exposure. They are high-performance adhesives used in the construction of aircraft, automobiles and boats, and they can be developed to suit almost any application for wood, metal, glass, fiberglass, stone, and some plastics. While these adhesives provide high adhesion, low shrinkage and high fatigue resistant, the downside is it requires a lot of surface preparation, have a long cure time and can have a low peel strength.

Then some people may think of Gorilla GlueTM. This glue is a polyurethane adhesive that, like two-part epoxies, can bond to a variety of substrates, is resistant to water, heat and cold, and can be used for a variety of purposes. It’s faster setting than epoxy adhesives yet expands after it is applies, and, unlike epoxies, can be sandable, paintable and stainable. Polyurethane adhesives, however, generally do not have as high “lap shear strength” as epoxies. This lap shear strength is a measure of an adhesive’s ability to endure the force applied to bonded substrates that get pulled in opposite directions.

There are other adhesives out there that are considered the “strongest” but only relative to the application. For example, there are chemical adhesives that actually chemically bond two surfaces becoming as strong as the substrate they are applied to. There is even a bacteria that can attach to solid surfaces which is the strongest glue known to exist in nature but only develops in the presence of water.

So, in the end, being the strongest glue really depends on what you put the adhesive on, what the intended use is for, and how it is applied. Hence, it’s all relative.

I was recommended to buy a good very strong stage adhesive and not having a clue on this sort of purchase was hoping you can help. I am wanting to stick false nails onto my big toes which have only skin there. No amount of super glue or similar will hold much longer than a few hours. Can you recommend an adhesive please? I understand it will be at my own risk and am willing to give it a try. Many thanks G Edwards.

I had both of my toe nail break off completly. When I went to my nail technician I said I was only doing my finger nails due to the big toes being gone. All of the technicians and the shop owner discussed the situation and came up with a solution. Their solution was to use their nail glue adhesive to attach the proper sized "false/fake" if you will... toe nail. Then once attache'd they proceeded to apply acrylic over it the same way you would to a finger nail. They sanded down and buffed and prepped also the same as they when applying a finger nail tip. Afterwards polished a couple coated and then a top coat ...still...the exact same process as a finger nail. Those stay on for the better part of a month!! I was truly amazed an would most definately do that again when needed.

New or Used Bibles Needed for the Poor! Demand Great! Please Help! Churches, Christian learning institutions, families and individuals will have Christian literature that is not being used but they don’t know what to do with them. Now you have the solution. There is a great demand for new or used Bibles, new testaments, Bible dictionaries, Sunday School materials, hymnals, gospel tracts, concordances, books from Christian authors, and other Christian literature for the needy. Any of these items can be new or used. Prayers, postage, volunteer help and financial donations makes a difference also. Any way you or your church, your members or affiliates can help make a difference is greatly needed and appreciated. Some churches assign certain departments (Sunday School, Missionary, Vacation Bible School, Youth, Deacons, Congregational, Choir, Ushers, Choir, Men's Group) to collect funds or literature as a one time project, quarterly, semi-annually or ongoing. Please visit http://www.cribooks.org OR http://www.elhm.org Be a part of translating the Bible into over 2,200 languages. visit http://www.wycliffe.org Whatever assistance is given isn't to small and is wholeheartedly embraced. Gilbert Stone, helping others through others because of the love, grace and mercy God has shown me!

I'm sure I have some extra Bibles around our house. I'll try to get them together and send them to you. I have a favorite and really, the one is all I need. And I would be glad to share the others with those who might need and can benefit from receiving them.
