There are a few things people love to have when they are in a pinch. When you have a flat tire it’s useful to have a spare, when you find yourself in the middle of a blackout it’s useful to have some candles, and when aluminum products break, it is useful to have an aluminum epoxy. This being said, what makes a good aluminum epoxy?<\/p>\n

What Should You Look for When Buying an Aluminium Epoxy?<\/h2>\n

There are a few characteristics you should look for when selecting an epoxy for aluminum, given that not every product on the market will tick all the boxes, but you should be aware of what your product is and is not capable of adhering to. Let\u2019s have a look at some important characteristics to keep in mind.<\/p>\n

\"Best<\/p>\n

 <\/p>\n

Tensile Strength<\/h3>\n

Tensile strength is usually used to measure the strength and impact resistance of solid objects like wood and metal, however, in the context of epoxies it indicates to which degree the epoxy can adhere to a surface before its bond is broken.<\/p>\n

Choose the best epoxy for aluminum your project demands, and keep in mind that if the price is not an object for you, it\u2019s better to have an epoxy that might be considered \u201coverkill\u201d in the PSI department than one that\u2019s slightly cheaper but has the adhesive bond of paper glue<\/a>.<\/strong><\/span>\u00a0<\/span><\/p><\/blockquote>\n

Tensile strength is measured in pounds per square inch or PSI for short and will often be noted on either the leaflet or box you purchase your epoxy in, therefore always ask a sales assistant or consult the epoxy\u2019s manufacturer website to ensure the product you have purchased is conducive to the load it will be supporting and more importantly the surfaces you are attempting join.<\/p>\n

Once you know what the strength rating of your epoxy is, always know what strength you will need for your workpiece beforehand to avoid disappointment, epoxies have been known to possess a tensile strength anywhere between 500PSI and 3000PSI.<\/p>\n

Resistance to Water<\/h3>\n

It is said that the cornerstone of a great martial artist is not using brute force to overpower your opponent, rather using the minimum amount of force required and knowing how to apply it efficiently. This is a lot like choosing the right tool for the job, and when choosing an aluminum repair epoxy, you should know exactly how you intend to use it and what potential forces your workpiece will be exposed to. Should your workpiece be exposed to rain or be submerged in water you should consider using a water-resistant or waterproof epoxy<\/strong><\/a>.<\/p>\n

Most epoxies on the market today are not water-soluble, so they have a small degree of water resistance to them.<\/strong><\/span><\/p><\/blockquote>\n

If you will be submerging your workpiece it is best to purchase a waterproof epoxy or a water-resistant epoxy should your workpiece only be exposed to water on occasion. Water-friendly epoxies are often a bit more expensive than conventional high tensile epoxies due to the expense involved in formulating the waterproof solution, but they often pay for themselves much sooner than later, especially when your workpiece doesn\u2019t fall apart due to a drizzle.<\/p>\n

 <\/p>\n

Ease of Application<\/h3>\n

How many times have you gone out and bought some coffee instead of making some at home? Have you ever asked yourself why you do this? Well, generally speaking, on a subconscious level, everyone looks for the easiest solutions to their problems.<\/p>\n

When your pen runs out of ink you simply buy a new one, when you want something to eat you just order something for delivery. Refilling your pen and making something in the kitchen are often our second choices because they are easier solutions that save us time, even though they can cost us a bit more money in the long run. With this reasoning in mind, epoxy and variations of these adhesives come to parts that you have to mix, namely the epoxy itself and the hardener.<\/p>\n

\"Aluminum<\/p>\n

They also vary in the manner in which they are mixed and applied, the most common of which involves you combining the two parts in a separate container\/pallet and then quickly scooping it up and applying it to your workpiece. The premium application method is present in the form of a double-barrel syringe, one holds the epoxy and the other hardener. This not only saves you the minor heart attack related to mixing and applying the solution in time, but it allows you to apply the precise amount you need for that particular job.<\/p>\n

 <\/p>\n

Resistance to Heat<\/h3>\n

One could group water resistance and resistance to heat under the versatility category. Having an epoxy that is resistant to heat and moisture is beneficial and sometimes absolutely necessary. This is obviously dependent on the application, and with this in mind, you should always consider what the heat tolerances and temperature of the environment of your workpiece are or will be.<\/p>\n

Depending on the grade of the epoxy you purchase, it will have a set temperature as well as a maximum tolerance temperature it can handle which will be indicated on the leaflet inside the packaging or in the packaging itself. You should pay special attention to these instructions because if epoxy is applied in an environment where the temperature is too high for the hardener and the epoxy to form the solution, you will be stuck with a toxic mess.<\/p>\n

\"Aluminum<\/p>\n

Temperature tolerances are also super important, they will often tell you which cold or hard temperatures will break the bond between the epoxy and your workpiece. The last thing anyone wants is to find that their newly repaired workpiece (and hard work) has been foiled by a cold spell or freak heatwave.<\/p>\n

These tolerances will also give you a good indication of where an aluminum repair epoxy can be used, for example, an epoxy that cannot handle heat above 220 degrees Fahrenheit will not be suitable for use in a car\u2019s engine bay.<\/p>\n

Remember that metals are incredible conductors of heat and therefore taking temperature into account will save you from having to do a second repair job.<\/strong><\/span><\/p><\/blockquote>\n

Hardening Time Frame and Aesthetic Appeal<\/h3>\n

Whoever said \u201cA quick fix for a long-standing problem only works for the short term\u201d has clearly never used aluminum epoxy filler<\/strong><\/a>. Epoxies are available in a variety of hardening and curing times and depending on the brand and application. Drying and hardening times won’t really have an effect on the quality of the adhesive, but it helps to know how long of a wait you will be in for, especially if the completion of your workpiece is time-sensitive. Remember to always check the drying and hardening times of the epoxy you will be buying if you need something that will dry and harden quickly.<\/p>\n

\"Does<\/p>\n

Aesthetics are arguably as important as functionality in some disciplines, this being said if you will be using aluminum epoxy filler for crafting purposes you probably want to paint over it or sand it down to create a flush surface. In this case, you should choose an epoxy that is conducive to this application because finding out that you can\u2019t alter the epoxy once it has been dried and hardened means you will have to find a way to dissolve it, clean the surface of your workpiece and start from the process from the beginning again.<\/p>\n

What Is the Best Epoxy for Aluminium?<\/h2>\n

Now that you know which characteristics to look for when choosing an aluminum epoxy filler, let us have a look at some of the best aluminum epoxies on the market today, as well as the pros and cons that each presents. Remember that this is an objective review, and the best epoxy for aluminum is the one that best suits your specific application.<\/em><\/p>\n

Best Overall Aluminum Epoxy: J-B WELD SteelStik Steel Reinforced Epoxy<\/h3>\n

If you have ever needed to repair something that simply should not be broken at the very second you need to use it, or accidentally tore off a piece of your car\u2019s front bumper, you have probably heard of JB Weld.<\/p>\n

For those who don\u2019t have the time or the tools for a \u201cproper\u201d fix JB Weld Steelstik provides a strong adhesive bond to both bind and seal off any break or void, you could possibly throw at it. Unlike other two-part adhesives, Steelstik from JB weld comes in the form of an adhesive putty which not only makes it easy to apply but is easily manipulated, sculpted, sanded, and even tapped, regardless of whether you have any experience with high strength epoxies.<\/p>\n
