A Coated Metal Gluing Challenge?
Gluing powder coated metals?
Another exciting week for our laboratory. Rubber gluing, metal gluing and plastic gluing. All industrial manufacturing tasks for which we had the ideal glue.
One material which occasionally enters our test laboratory, is powder coated metal. This week, a major fabricator of decorative cladding for building facades, contacted our laboratory.
The question, a structural adhesive which is capable of bonding powder coated 2.7 mm thick aluminium to itself, and cross bonding powder coated aluminium to aluminium.
The solution…simple. Scigrip SG300, the two component metal and composite bonding adhesive which boasts exceptionally high fatigue resistance and exceptional shear strength.
The proof was needed. Our engineer cut the customer supplied substrates. Next over to the chemist. She applied a film of SG 300, to a glueline thickness of 0.5 mm. Nine single lap-shear specimens were produced, six being tested. Surface preparation was a cinch, a quick wipe with our 100% biodegradable DP 526 degreaser.
This test was carried out to the procedure laid down in ASTM D 1002 (Standard Test Method for Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Tension Loading (Metal-to-Metal). Twenty four hours later, back to the engineer and straight into our Zwick Roell Z030 ProLine.
The result, as expected. 600 kgs of tensile caused the aluminium to stretch 4 mm and to shear. The SG300, wondering what all of the fuss was about!
