摘要

Oligu00c8mero or polu00ecmero crystalline or semicristalino, composition comprising at least one oligu00c8mero or polu00ecmero crystalline or semicristalino, process for providing a substrate with a coating flexu00ecvel, substrate coated with a coating composition and use of a composition. Of the coating.The invention concerns materials and compositions of polymer powder coating thermally curable or curable by ultraviolet radiation (13V) with low cooking temperature for flexible substrates and / or sensitive to heat.More specifically, such materials and polymer powder coating compositions are based on polymers crystalline or semi crystalline, but when subjected to melting or flow at low temperatures (60 u00b0 C to 140u00b0c) and under cure in the state in fusion energy by radiation from 13V or Thermal,It will provide coating (highly) or flexible polymeric matrix having low glass transition temperature (TG), non crystalline, amorphous or complete low Tg polymeric matrix, with a low degree of crystallinity.
