Abstract
An aluminum substrate comprising a layer of lamellae of a layer mineral, preferably vermiculite, in which substantially all of the lamellae are of size below 50 microns, production of the coating by applying a suspension of the lamellae to the substrate and removing the liquid from the suspension. The coating significantly upgrades the thermal insulation and fire performance of aluminum substrates even when only a few microns, for example below 50 microns and even below 10 microns, in thickness.
