An investigation of the mechanism of lacquer adhesion failure on electrolytic tinplate. "Tin" cans used for food packaging are actually made from tin-plated steel and, in most cases, the metal is coated with a lacquer. This lacquer is required to protect the can from corrosion and the contents from taint. The incidence of adhesion failure between the metal and the lacquer has increased recently for unknown reasons, causing considerable economic loss. This project will investigate the mechanisms ....An investigation of the mechanism of lacquer adhesion failure on electrolytic tinplate. "Tin" cans used for food packaging are actually made from tin-plated steel and, in most cases, the metal is coated with a lacquer. This lacquer is required to protect the can from corrosion and the contents from taint. The incidence of adhesion failure between the metal and the lacquer has increased recently for unknown reasons, causing considerable economic loss. This project will investigate the mechanisms of adhesion failure and improve our fundamental understanding of the problem. The results will be used to enable the selection of process conditions and lacquers that are more robust and reduce the incidence of adhesion failure.Read moreRead less
Nano-scale Modification of Paint Surfaces for Contamination Resistance. The main aim of this work is to develop a process to produce a dirt resistant paint surface. Dirt resistance is an important characteristic of prepainted steel sheets often used in architectural situations where dirt build-up is unsightly. To develop the process it will be necessary to understand the mechanism of dirt adhesion to paints and the modes of operation of current dirt resistant processes. In addition work will be ....Nano-scale Modification of Paint Surfaces for Contamination Resistance. The main aim of this work is to develop a process to produce a dirt resistant paint surface. Dirt resistance is an important characteristic of prepainted steel sheets often used in architectural situations where dirt build-up is unsightly. To develop the process it will be necessary to understand the mechanism of dirt adhesion to paints and the modes of operation of current dirt resistant processes. In addition work will be required on the rate of surface segregation of additives to the paint solution. We propose to combine experimental and theoretical modelling approaches to obtain a fundamentally sound practical solution.Read moreRead less
