Influence of the Atomization Gas in Coating Processes

Dr. Oliver Tiedje

Atomization plays a crucial role in spray coating processes. The liquid paint is broken up to small droplets and accelerated to the work piece. A conflict of goals is appearing here: A high quality of the layer requires usually a fine atomization, but small droplets can lead to enhanced overspray. Discussions regarding the use of other atomization gases than air shall be focused to a systematic base in this article. PDF-Download

Cost-Effective Coating for Vehicles

Edgar Romey

Modern coating systems have to fulfil a wide range of requirements as a result of environmental legislation, growing pressure on costs and the high standards of vehicle manufacturers. A vertical water-borne coating system consisting of a primer and a top coat has proved its value in the automotive industry, as the example of a company that manufactures vehicles shows.

German Cleaning Systems for Asia

Gerhard Koblenzer

Asia is a growth market and the demand for high-quality cleaning systems there is constantly increasing. This is why the Surface Alliance invited the Indian machine manufacturer NGCT, which is based in Pune, to become a member of the association of companies in 2010. Since then, production levels have constantly risen and the manufacturing site has been developed further. This article explains the benefits of producing German products in India and the accompanying requirements. PDF-Download

Improved Long-Term Protection for Agricultural and Construction Machinery

Thomas Willumeit

Agricultural and construction machines operate in very tough conditions. Alongside a high-quality surface finish, the cost-effectiveness and flexibility of the pre-treatment system are playing an increasingly important role. A newly developed, phosphate-free process that can be used with a variety of metals provides excellent long-term protection for machinery and vehicles. PDF-Download
