Moderne Verfahren zur Beschichtung zementgebundener Untergründe

Modern Procedures for Coating of Cement Bound Grounds Still up to the middle of the sixties freshly prepared cement bound rough-casts and concrete surfaces were thought to be very critical grounds for painting. The effect of the high alcality of these grounds in connection with the residual humidity of the building and the influence of the weather was especially feared, which could cause saponification of the binding agent and destruction of inorganic colour pigments. Especially at concrete surfaces difficulties with adhesion of the paints on concrete were added, since at that time in building practice again and again pollution of the concrete surfaces by lagging oils and waxes occured. Defects by flaking off were the outcomes. Only when concrete pushed forward quickly in housing construction, where prefabricated building with prefabricated elements played a decisive role, special painting and coating systems were developed which allowed not only a durable protection of concrete, but moreover a colour fashioning. In the same measure as security in concrete painting was achieved, the difficulties in painting of cement containing rough-casts were solved. According to the state of the technic of today tested and well proved painting systems for coating of cement bound rough-casts and concrete are available.     

Durability of powder-coated hot-dip galvanized steel

In this study, the quality and durability of powder-coated hot-dip galvanized products have been investigated. Standard steel coupons hot-dip galvanized in conventional and delta (i.e., high temperature) conditions were coated with powder paint systems or a high quality solvent-based system and then subjected to a wide range of test methods representing mild or highly aggressive exposure conditions. Additional variables in the project were the silicon content of the steel and the treatment prior to painting. The use of delta-galvanized steel as a base for painting offers a number of advantages such as much greater hardness and improved paint adhesion. Maximum corrosion protection is observed if the galvanized base is treated with chromate and sequentially powder coated with an epoxy primer followed by a polyester topcoat. Weert Groep. P.O.

High performance polyaniline containing coating system for wet surfaces

Application of paint coatings on wet surfaces is rather difficult due to poor adhesion of coatings. For painting of wet surfaces, moisture curable coating systems based on epoxy resin and ketimine are found to be useful. Hence a study has been made on the corrosion protection ability of coating on wet surfaces using epoxy resin, ketimine and polyaniline. Paints with 20–30% PVC were prepared and applied over the wet steel surface and the corrosion protection performance of the coating was found out by salt spray and electrochemical impedance spectroscopic techniques. Coating with 20% PVC is found to offer very high protection since the impedance values are remained at greater than 10⁹ Ω cm² after immersion and salt spray tests.
