Powdercoat | Standards

There are BS and ISO standards for the application of powdercoating onto metal substrates that allow specifiers to have a recognisable means to ensure quality. In addition, powder manufacturers have a system of auditing applicators of their powders to ensure recognition of good practice, and identification of non approved applicators.

The leading powder manufacturer, Akzo Nobel, through their product brand Interpon, operate an approved applicator evaluation scheme review for powder coating onto a galvanized substrate. The mechanical and chemical pre-treatment for this substrate is much more rigorous than the standard for powder coating onto any other substrate, such as aluminium. As a result, whilst there are many approved applicators onto an aluminium substrate, Highland are the only approved jobbing applicator onto a galvanized substrate north of London.

Details of the rigorous auditing and testing required to become an approved applicator are provided independently on the Akzo Nobel website.

As a result our Approved Applicator status for a galvanized substrate, Highland are able to offer a full guarantee system. Further details of this are provided at the base of this text.

Notes

ISO standards are reviewed and revised about every 5 years. It is important to be using the latest version of the standard. The fact that no standard is available for powdercoating on bare steel is a good indication that such a process is not advised. However when this is requested then BS EN 13438:2005 is adopted.
