Question: I am working on a new metal finishing project and have been given the responsibility of removing volatile organic compounds (VOCs) from the air exhaust using activated carbon.

UV-curable coatings provide energy savings—operational bonuses

Corrosion and appearance requirements for plated steel parts continue to increase, while at the same time ever more restrictive environmental regulations are being put into place. As if these hurdles are not challenging enough for both process suppliers and applicators, there exists the compelling directive to reduce costs. Much of this is initially introduced by the European automotive industry, but then quickly spreads to automakers worldwide and to most other industries. In the field of zinc plating, the focus is on the protective conversion coatings and top coats that are applied to the zinc deposit. This paper examines the advantages of new cobalt-free technology as well as what is on the horizon regarding future requirements and regulations for zinc plating.

Question: I have some thoughts that I want to convey about Repainting Steam Locomotives that appeared in the November 7, 2002, issue of Painting Clinic.

UV-Cured powder coatings are viable substitutes for solvent liquid coatings

Products and systems that can help finishers comply with environmental regulations

Question: I am chair of a historical society paint committee which is trying to determine the correct paint colors used by a long-defunct railroad company for their equipment and structures.

Question: We epoxy powder coat a product line that is about 50% brass, 25% bronze and 25% nickel-plated brass.

I am an engineer on a large yacht build project and urgently need information and advice on choosing a finish for the aluminum deck plates in the engine room.

This paper shows information learned from a NASF/AESF Foundation Research grant which has led to successful application. The work at the University of Houston (UH) is discussed – a technique developed to perform in-situ analysis of the stress of the chromium deposit from a REACH-compliant trivalent chromium electrolyte. An understanding of crack formation during plating has led the way to a means to avoid it. Faraday Technology Inc. scaled-up and optimized the same process through support from the U.S. Army. The results enabled significant chromium coating performance enhancements, matching the wear index of conventional Cr deposits from hexavalent baths.
