DEVELOPMENT AND ASSESSMENT OF THE POLYESTER POWDER FILM TRACEABILITY OF COATED PROFILES: THE POWDER DNA

Preliminary remarks

In January 2011 the coating plant for aluminium profiles belonging to the Brazilian Aluminium Company – Votorantim Metais started up. In order to provide assurances about the origins of the powder to frame makers, and mainly to CBA/Votorantim Metais clients, an identification system was developed that allows the type of powder used to be checked, if the coating process was done in the CBA plant.

In fact, during the powder manufacturing process an agent was added to the formulation that allows the product to be identified by means of a system that scans the surface of the coated profile. The identification of the origins of the powder attests to and guarantees the durability of the coated profiles.

This article was presented by the author to the fifth international aluminium congress, which was held in San Paolo, Brazil, from 24 to 26 April 2012.
