  • Pinholes And Outgassing Troubleshooting Your Powder

     · Pinholes can occur with some powder coating materials when they are applied in one heavy coat of greater than average thickness. When this happens gasses that escape during curing are released through the outer surface of the coating after it has begun to cure causing imperfections in the surface that remain after the part has cooled.
