Although aluminum is a common bonding substrate for epoxy anodized aluminum can present its own set of bonding problems.
Bonding aluminum to aluminum epoxy.
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.
Single component epoxies are ideal for bonding aluminum.
So it kept the reputation.
It has a tensile strength of 2424 psi and heat resistance of 300 degrees fahrenheit.
Bonding with this adhesive is extremely resilient and durable.
Thicker aluminum oxide layer increased porosity and increased strength brittleness.
So the strength isn t the same but it s more than the industry average.
Epoxy adhesive is available in one or two component versions.
The best aluminum glue.
Ms polymers form weather resistant bonds to aluminum and have very low shrinkage rates.
For very high strength use a metal bonder such as 170 or the original 910.
They are popular in the construction industry.
Single component epoxy aluminum adhesives cure with heat to form high strength structural bonds.
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.
In order to bond aluminum you ideally need a construction adhesive.
Like slow and medium metal bonding adhesives fast metal bonding adhesive also guarantee corrosion protection replaces welding and has the fastest de clamp.
Consider es550 or es558.
As we said earlier this one s just a quick setting version of the strongest bond creating metal epoxy.
Aluminum resists corrosion because a thin layer of aluminum oxide forms almost immediately when the bare metal is exposed to air.
All grades will bond aluminum well.
Anodized aluminum is an electrolytically induced passivation process where several physical changes occur to the surface including.
