Bonding Aluminum To Aluminum Epoxy

As we said earlier this one s just a quick setting version of the strongest bond creating metal epoxy.

Bonding aluminum to aluminum epoxy.

Aluminum resists corrosion because a thin layer of aluminum oxide forms almost immediately when the bare metal is exposed to air. It has a tensile strength of 2424 psi and heat resistance of 300 degrees fahrenheit. They are good for bonding large areas providing a moisture seal and can even be painted over. Although aluminum is a common bonding substrate for epoxy anodized aluminum can present its own set of bonding problems.

Thicker aluminum oxide layer increased porosity and increased strength brittleness. Single component epoxies are ideal for bonding aluminum. Ms polymers form weather resistant bonds to aluminum and have very low shrinkage rates. Like slow and medium metal bonding adhesives fast metal bonding adhesive also guarantee corrosion protection replaces welding and has the fastest de clamp.

For very high strength use a metal bonder such as 170 or the original 910. Single component epoxy aluminum adhesives cure with heat to form high strength structural bonds. Anodized aluminum is an electrolytically induced passivation process where several physical changes occur to the surface including. Fast metal bonding adhesives are generally used to patch metal bonding and bond dissimilar metals such as metal corners panel sections and patch repairs for trailers made of aluminum.

It is nearly always alloyed to improve its mechanical properties. Bonding with this adhesive is extremely resilient and durable. Aluminum is a relatively soft durable lightweight ductile and malleable metal that is easily machined cast drawn and extruded. So the strength isn t the same but it s more than the industry average.

So it kept the reputation. Epoxy adhesive is available in one or two component versions. Consider es550 or es558. The best aluminum glue.

For bonding aluminum to dissimilar surfaces with different coefficients of thermal expansion consider toughened 737. To glue aluminum you have the choice of three different types of adhesive.
