EcoTri? ONE plated zinc nickel fasteners
BERLIN, April 2018: EcoTri? ONE is Atotech’s latest fluoride-free, iridescent thick film passivate. This all-in-one passivate is equally suitable for zinc or zinc nickel surfaces while giving excellent corrosion protection – a major advantage for customers because only one passivate tank is necessary in the plating line for zinc and zinc nickel plated parts. Ultimately, this results in a significant reduction of time, space, maintenance and handling costs.
EcoTri? ONE shows an outstanding corrosion protection of up to 168 h against white corrosion on zinc and up to 300 h on zinc nickel. With a lifetime of more than 36 m2/l without new make-up, the innovative passivate helps to reduce both internal costs and external environmental impact. The new high performance passivate provides customers with a wide range of color options, combining protection with an attractive appearance – from iridescent to bluish. Adjusting production parameter accordingly, a stainless steel look is achieved without applying a sealer or top coat. Very good color stability is maintained even after hydrogen de-embrittlement baking.
EcoTri? ONE contains less Cr(III) compared to conventional high performance thick film passivates available, making waste water treatment simpler and economical. And like all members of the EcoTri? family, EcoTri? ONE is also suitable for Atotech’s regeneration system Tricotect?. Tricotect? allows for the continuous and selective removal of iron and zinc build-ups from passivate solutions, ensuring constant high plating quality and preventing hazing and discoloration of passivate films.
