The supertuff coating introduced by alfagomma is chromium (VI)-free and resists

400 hours in salt spray fog. Alfagomma guarantees a long-lasting service life for its products in a highly corrosive environment, thanks to the innovative SUPERTUFF coating. Laboratory tests in salt-spray environment, carried out in compliance with ISO 9227 and ASTMB117, show a corrosion resistance 4 times higher than the standard: 400 hours compared to the 96 hours prescribed by the ISO Standard.

Alfagomma also confirms its commitment to environment protection: all the products are coated without Chromium (VI)-free, element banned by the European directive 2000/53/EC (end-of-life policy for vehicles).
