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
Why is ColorbondR steel greener on the other side of the fence? Designing additives to retard weathering of surface coatings. COLORBONDR steel, the flagship pre-painted steel product of BlueScope Steel Limited, has become an iconic part of both suburban and outback landscapes whether installed as roofing, walling or water conservation accessories (tanks, down-pipes etc). This proposal aims to provide a detailed understanding of molecular level changes in COLORBONDR steel surface coatings brought ....Why is ColorbondR steel greener on the other side of the fence? Designing additives to retard weathering of surface coatings. COLORBONDR steel, the flagship pre-painted steel product of BlueScope Steel Limited, has become an iconic part of both suburban and outback landscapes whether installed as roofing, walling or water conservation accessories (tanks, down-pipes etc). This proposal aims to provide a detailed understanding of molecular level changes in COLORBONDR steel surface coatings brought about by levels of heat and radiation encountered in-service. These insights will lead to further improvements in both lifetime and aesthetic durability of COLORBONDR steel, ensuring continuing economic success of BlueScope in the domestic building market with consequent benefits to manufacturing communities throughout the supply-chain nationwide.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

Summary
Multidisciplinary 'Environmental' Field Emission Gun Scanning Electron Microscope. The present proposal is for a high resolution electron microscope for use in the development of new materials for the automotive, textile and bio-medical sectors. The new generation of automotive materials will be lighter and more crash resistant. New textiles will be 'active' in providing warmth and cooling through their conducting properties. They will also provide enhanced dynamic protection against physical ha ....Multidisciplinary 'Environmental' Field Emission Gun Scanning Electron Microscope. The present proposal is for a high resolution electron microscope for use in the development of new materials for the automotive, textile and bio-medical sectors. The new generation of automotive materials will be lighter and more crash resistant. New textiles will be 'active' in providing warmth and cooling through their conducting properties. They will also provide enhanced dynamic protection against physical harm. The facility will support the development of new cellular scaffolds made from metals and polymers. These scaffolds will be used for tissue growth and engineering. The facility will also be used to support Deakin University's regional collaborators.Read moreRead less
Novel Coatings For Steel. The aim of this project is to design coatings for steel that have high flexibility and high resistance to scatching and hardness. This will be achieved by the introduction of liquid crystalline phases in the coatings. The outcome will be a new generation of steel coatings with novel properties
Improving Energy Efficiency through Cool Polymers in Building Materials. The advantages of using cool polymers in industrial applications such as building materials are significant. Cooler buildings are a positive contribution to our global environment with reductions in urban heat and smog through energy efficiency. Moreover, by reducing the overall temperature of the surface coating through inclusion and optimization of IR-reflective pigments, this should lead to polymers which are more durabl ....Improving Energy Efficiency through Cool Polymers in Building Materials. The advantages of using cool polymers in industrial applications such as building materials are significant. Cooler buildings are a positive contribution to our global environment with reductions in urban heat and smog through energy efficiency. Moreover, by reducing the overall temperature of the surface coating through inclusion and optimization of IR-reflective pigments, this should lead to polymers which are more durable when exposed in exterior environments. It is anticipated that the results from this work will have direct impact on the Australian paint market and potentially the commercial and residential building industries of Australia, combined with obvious economic benefits.Read moreRead less
Performance Chemistry of Thermoset Surface Coatings. Surface coatings employed in the COLORBOND® range of pre-painted steel products are remarkable materials that are warranted against fading, peeling and cracking for 25 years. Unfortunately, the desired durability can never be uniform across all applications and performance failures do occur and are costly. Classic durability testing often provides misleading information. This project aims to develop a sound mechanistic model for polyester-is ....Performance Chemistry of Thermoset Surface Coatings. Surface coatings employed in the COLORBOND® range of pre-painted steel products are remarkable materials that are warranted against fading, peeling and cracking for 25 years. Unfortunately, the desired durability can never be uniform across all applications and performance failures do occur and are costly. Classic durability testing often provides misleading information. This project aims to develop a sound mechanistic model for polyester-isocyanate performance chemistry and to develop strategies for 'superdurable polyester' formulations based on these findings. This research will provide recommendations to BHP Coated Steel Australia on adoption of isocyanate based technology in the COLORBOND® range of products.Read moreRead less
