Abstract
The object of the present invention is an improved hard coating process using a polyol in powder form, enabling easy, speedy creation of a hard coating on the surface of a product. This process consists, on the one hand, in the application of a syrup containing at least 90% of a polyol chosen from sorbitol, maltitol, mannitol, xylitol, erythritol, lactitol and isomalt and, on the other hand, in the application, in powder form, of a quantity of powder which has a purity higher than 95% with respect to this same polyol; these applications being performed without carrying out a forced drying.
