UniBond 1381190 Repair Power Epoxy Plastic - 25 ml

Product Information

The epoxy curing reaction may be accelerated by addition of small quantities of accelerators. Tertiary amines, carboxylic acids and alcohols (especially phenols) are effective accelerators. Bisphenol A is a highly effective and widely used accelerator, but is now increasingly replaced due to health concerns with this substance. Epoxy adhesives are a major part of the class of adhesives called "structural adhesives" or "engineering adhesives" (that includes polyurethane, acrylic, cyanoacrylate, and other chemistries.) These high-performance adhesives are used in the construction of aircraft, automobiles, bicycles, boats, golf clubs, skis, snowboards, and other applications where high strength bonds are required. Epoxy adhesives can be developed to suit almost any application. They can be used as adhesives for wood, metal, glass, stone, and some plastics. They can be made flexible or rigid, transparent or opaque/colored, fast setting or slow setting. Epoxy adhesives are better in heat and chemical resistance than other common adhesives. In general, epoxy adhesives cured with heat will be more heat- and chemical-resistant than those cured at room temperature. The strength of epoxy adhesives is degraded at temperatures above 350°F (177°C). [46] Epoxy adhesives need to be mixed in a precise ratio, but many products come in pre-measured syringes which you can then use to apply. Some epoxy adhesives also come in the form of a two-part putty or paste, which you then have to knead together before application.

In the aerospace industry, epoxy is used as a structural matrix material which is then reinforced by fiber. Typical fiber reinforcements include glass, carbon, Kevlar, and boron.

As adhesives, epoxies bond in three ways: a) Mechanically, because the bonding surfaces are roughened; b) by proximity, because the cured resins are physically so close to the bonding surfaces that they are hard to separate; c) ionically, because the epoxy resins form ionic bonds at an atomic level with the bonding surfaces. This last is substantially the strongest of the three. [50] By contrast, polyester resins can only bond using the first two of these, which greatly reduces their utility as adhesives and in marine repair. If you are looking for the strongest glue available for small plastic parts that require extraordinary strength, this may be your best option. It will repair plastic, wood, metal, glass, stainless steel, AVS, PVC, ceramic, acrylic, and more. You can use it to repair valuable jewelry because it creates a permanent bond in five to 10 seconds.

You basically cut then knead the putty, it should begin to form an even color, then apply to the area that needs to be repaired. All-in-all, you have ten minutes to knead, mix, and then use it. The epoxy will harden in 60 minutes and after 24 hours it will harden thoroughly. Bayliss, D.A.; Deacon, D.H. (2002). Steelwork corrosion control (2nded.). London: Spon. pp.13.6.6 Chalking.

Another giant of the glue world, Gorilla Glue may have only been around since 1994, but since launch it has gone on to achieve an enviable reputation among adhesive manufacturers worldwide, and its Epoxy offering is an excellent example of why.Hardeners which show only low or limited reactivity at ambient temperature, but which react with epoxy resins at elevated temperature are referred to as latent hardeners. When using latent hardeners, the epoxy resin and hardener may be mixed and stored for some time prior to use, which is advantageous for many industrial processes. Very latent hardeners enable one-component (1K) products to be produced, whereby the resin and hardener are supplied pre-mixed to the end user and only require heat to initiate curing. One-component products generally have shorter shelf-lives than standard 2-component systems, and products may require cooled storage and transport. A: Probably not. Most are polyethylene, a very slippery plastic like a milk jug. If it is any other material, it may work. The Application of Epoxy Resins for the Restoration of Historic Structures".

Primary amines undergo an addition reaction with the epoxide group to form a hydroxyl group and a secondary amine. The secondary amine can further react with an epoxide to form a tertiary amine and an additional hydroxyl group. Kinetic studies have shown the reactivity of the primary amine to be approximately double that of the secondary amine. Use of a difunctional or polyfunctional amine forms a three-dimensional cross-linked network. To use, ensure surfaces to be joined are clean, completely dry and close fitting. Using the Surface Activator like a pen, apply it to both surfaces and wait 60 seconds for it to dry. Open the glue and carefully squeeze a small drop onto one surface. Press the surfaces together and hold until set.
