Specialists in Lacquering Aluminium Coils

Alucoat® coil

bobinas-alucoat-clopp-farmaciaAlucoat® coil is the designation of ALUCOAT for the high thickness liquid lacquered aluminium products processed throughout our state-of-the-art coil coating line. The use for these kind of  products are the production of composite panels, profiled sheets, folded sheets, ventilation conducts and formats for different sectors. The aluminium is treated by  Alucoat® prelac, a degreasing and pre-treatment process patented by ALUCOAT that improves protection against corrosion and the lacquer adherence over the aluminium surface.

Lacquers (PVDF, PE and HDPE) specially developed to meet the requirements of each end-use (exterior or interior applications) applied in liquid form, providing and uniform and smooth layer of paint. It has excellent flatness, surface finish and wide range of colors with constant color shades. Wide range of alloys, hardnesses, thicknesses and widths can be supplied according to the customer demand.
