What is the strongest epoxy glue I can purchase?

Epoxy glues are high-performance adhesives with a wide range of applications. They are used in  the construction of vehicles, as a coating or sealant, and for creative uses. They are common in the electronics industry, thanks to their insulating properties. Epoxies are effective on different materials, including wood, fabric, glass, or metal.

What are the properties of epoxy glue?

Epoxy glue consists of two separate components. The first part is epoxy. The other is a hardener. When the two mix together, a reaction causes the epoxy to dry. Once hardened (“cured”), epoxy glue assures a strong bond that is difficult to break.

Epoxies come in many types, with distinct properties: flexible or rigid, transparent or opaque, fast or slow setting. They also offer high resistance to heat and chemicals.

Added advantages of two-part epoxies are that they adhere to many substrates and cure at room temperature. They even bond many types of plastic. To de-bond, epoxies must be heated above 250°C to soften. Parts should be separated while the adhesive is still hot.

How strong is epoxy glue?

The tensile strength of a bond is measured in psi (pound per square inch). Tensile strength tells how strong an adhesive is. Epoxy glue has an average strength of 2900-4400 psi. It is not enough, however, to know the strength of an adhesive. You will also need to understand the specific type of strength.

An epoxy glue has great structural strength. This makes it a good choice for bonding gaps between two parts. Compared to a different kind of high-strength glue, like cyanoacrylate (Super Glue), epoxy offers better shear, impact and peel strength. This means that epoxy glue will resist off-angle stress. Super Glue, on the other hand, will hold best when the bonded parts are directly pulled apart.

Epoxy can work as a filler as well as an adhesive. It is suitable for gaps, holes, and cracks. When used on metal, it is strong enough to provide an alternative to welding. Epoxies can hold moving parts and load-supporting parts.

What is the strongest epoxy glue?

On July 12, 2019, DELO Adhesives lifted a 17.5 tons truck with a crane held by 3 grams of glue. This world record was obtained by using DELO MONOPOX VE403728. However, this adhesive is not commercially available.

The strongest epoxy glue you can purchase is probably Systemthree’s T-88. This two-part adhesive has a tensile strength of 7000 psi. It is well above the average strength for epoxies. T-88 exhibits outstanding adhesion and permanence on a wide variety of materials and is designed to resist adverse conditions. T-88 is endorsed by leading designers, builders and organizations.

Other strong epoxies you can consider are PC Products’ PC-7 Adhesive Paste and Loctite EA 109 High Temperature & Toughened. They are both designed to provide maximum resistance to impact, shear, cleavage and tensile loads. Both will bond to a wide range of surfaces.

    Enjoyed readin your article about properties and strength of expoxy

    I am repairing a Pioneer CT-F850 cassette deck (vintage 1979).
    The mechanical transport body is a dark, graphite gray colored plastic (ABS maybe) and a small standoff has broken off near it’s base.
    I need to reattach it, it doesn’t handle much physical load but rather acts as a pivot point for the half shell cassette hold down.

    Strength is vital as the the two reattachment points are very small. It need to set quickly and retain some resistance to flexing

    A recommendation for an epoxy is much recommended!

    Many Thanks.
    Clark B.

    In my experience, Its best to “weld” ABS plastic with modified soldering iron for optimal strength. there are several excellent videos on youtube for help.

  3. Temperature Sensor nz says:

    When it comes to determining which epoxy glue is the most durable, the information provided by is really helpful. Their article provides an explanation of the various types of epoxy and their respective strengths, thereby assisting readers in making an educated choice.

    On a V8 engine. The stole. The bolt goes into your head one broke dew to wrong bolt being used.?? Wil. Epoxy hold this

    • Gee says:

      Absolutely not! Temperature, surface preparation, tensile strength, all make epoxy unsuitable for “fixing” engine head bolts.
      Had one a**hole try and rip me off with an engine ‘fixed’ with glue.

  5. john Matthews III says:

    Extract the broken one, or Redrill and tap, etc., but epoxy is not the way to go in an engine environment.

  6. Oren says:

    What epoxy is strongest for ceramic to ceramic with it filling a gap in between the 2 parts. I tried PC11 and it did not hold.

  7. Martin Martinez says:

    Have an acrylic drum piece floor Tom ‘one of a kind’ accidentally dropped it. It sustained some hair line fractures and a triangle 3 x 3 inch piece broke off. What do you recommend what kind of epoxy I use Please assist

  8. Steve Elsass says:

    Will your epoxy glue hold up to 180 degree water? Will your epoxy glue hold up being applied on embossed metal insulated panels? Will the epoxy glue harm the finish of either white polyester paint or stainless steel finishes?
    we are constructing a new custom butcher shop, and the owner wants to apply an epoxy cove base, 6″ high onto the metal insulated panels and not use concrete curbs which is what is used in large processing plants.
    Will your product work well in this application?
