Process for coating plastic substrates with powder coating compositions. |
摘要 |
<p>A process of coating a preformed plastic sustrate susceptible to gassing upon heating characterised by the steps of: a) preheating the substrate at temperatures and for a time sufficient to degas the substrate, said temperatures being above the temperature sufficient to cure a subsequently applied powder coating composition; b) applying immediately a powder coating composition to the preheated substrate above the temperature sufficient to cure the powder coating composition; and c) heating immediately the coated substrate at a temperature and for a time sufficient to cure the powder coating composition, is disclosed. The method is effective in sealing the substrate against popping.</p> |
