At Sur/Fin 2018, MacDermid Enthone will highlight its DecoKlad quality assurance program for high-performance decorative automotive coatings, which aims to ensures globally consistent performance from a network of approved applicators.
MacDermid Enthone will highlight its DecoKlad quality assurance program for high-performance decorative automotive coatings, which aims to ensures globally consistent performance from a network of approved applicators.In a nutshell, the company: supplies and develops standards that exceed OEM specifications; validates applicator processes by conducting audits, carrying out inspections and testing production output to make sure it meets pre-defined standards and requirements; and monitors and reports results on a global scale to enable continuous performance improvement. Compliance with legislation such as ELV, RoHS and REACH also are essential requirements.
In this paper, a review of several process solutions, examining coolants, solvent cleaning, alkaline clean/etch and deoxidizing/desmutting, listing intended and unintended chemical reactions along with possible mechanisms that would favor corrosion formation.
This paper discusses recent research work on the development of a functional trivalent chromium plating process from a trivalent-based electrolyte to replace hexavalent chromium plating. Hexavalent chromium plating has been used for many years to provide hard, durable coatings with excellent wear and corrosion resistance properties. However, hexavalent chromium baths have come under increasing scrutiny due to the toxic nature of the bath, effects on the environment and workers’ health. In this paper are results from our development program aimed at achieving properties comparable to existing hexavalent chromium plating for functional applications. Specifically, recent efforts in plating chromium on the internal surfaces of cylindrical parts will be presented, as well as wear test data.
