Bonding ACM panels to Komatex panels for exterior use

[cthammond]

We generally use contact cement to bond our panels but most of our work is for interior use. Can someone recommend a good adhesive to bond ACM and Komatex to make a single panel. These will be large panels close to 4'x7'.

Thanks in advance.

You need an adhesive that bonds 2 diferent type of materials plastic + aluminium that can let each material to expand and contract to heat and cold independently.
for this you need to buy methacrylate type of adhesive (usually is bi-component).
if you use cyanoacrylate the komatex will crack because is a rigid adhesive. (but you can use it for initial glue from spot to spot to secure the material in the shape, and with methacrylate you fill the whole perimeter)
