2013 was an important year for ESTEGA as the automatic horizontal powder coating line was bought.
ESTEGA guarantees that the three processes for coating – pre-treatment, coating and polymerization in oven – fulfill quality standards.
Pre-treatment of aluminium profiles or sheets is a process for cleaning and degrease that enable later adherence of powder coating.
After that process, profiles and sheets go to coating booth where are sprayed with powder coating (polyester or polyurethane).
Finally, are polymerized in the oven (between 190 and 220 Celsius degrees) to fix it to the surface.
