Aluminum Composite Panels

A. It probably means painted with polyester resin paint or powder coated with polyester resin powder.

A. Alejandro,
I tried to powder coat these once, but they came apart in the oven so they are probably wet painted.

A. If it's the same material as we use in the sign industry ACS (aluminium composite sheet) the polyester probably refers to the core.

ACS is two sheet of Aluminium coil- normally between 0.40 & 0.70 mm.

The coils are pre-finished- not sure how. Some ACS is solid coloured so I presume it's wet painted. On the other hand some ACS is metal or stone effect so this isn't paint.

If you need ACS in a definitive colour there are various options;

1) Flood coat with self adhesive vinyl of the appropriate colour.
2) Wet spray
3) ACS manufacturers will provide you with virtually any RAL colour subject to a minimum quantity.

Hope this helps,

A. Hi Flloyd. A quick google search showed that one brand offered panels of 3, 4 or 6 mm thickness, with skins of 0.5 mm, and weights of 6, 7.6. and 10.9 kg/mm2. Their color coatings are fluorocarbon and range in thickness from 25 to 45 microns depending on whether plain, metallic, or 'imaged'. The back side has a wash coating.

It would seem from this that there are no unique answers to your questions even for panels from a single manufacturer.

Following up on Andy's response, the one manufacturer I quickly checked uses polyethylene cores for signage and non-combustible mineral-filled cores for interior and exterior panels.

Luck & Regards,
