Abstract:

In the search for improvements in the environmental credentials of the organic coatings industry, several different aspects are currently being addressed, including the reduction of volatile organic compounds, development of UV curable coatings and the reduction of potentially hazardous components in the coatings formulations. The aim of this work was to develop the water based primers for coil coating applications as a substitution for chromate conversion coatings. The performance and durability of three novel water based systems applied on alkali cleaned HDGS has been investigated; XPS and T

Abstract:

The deformable roll coating is used in the coil coating industry. The aim is to apply a liquid film on a moving substrate. During application a defect appears. This defect is called “ribbing” and is characterized by periodic ribs parallel to the moving direction of the substrate. The wet thickness applied on the strip is adjusted by different gaps between rolls. The applied speeds and loads on the rolls modify the film thickness and film stability. The elastomeric roll cover is used to permit thinner film application and to delay the onset of ribbing. In this work, the flow in a deformable con

This thesis deals with the determination of the effect of controlled relative humidity (RH) on the mechanical properties of coil coatings.

The study employed mechanical and dynamic mechanical analysis, using modified environmental chambers, to measure the effects of controlled RH on a range of mechanical parameters. Of particular interest was the effect of controlled RH on the minimum forming temperature of the coil coated metallic panels. This is the temperature below which the coating would fracture.

This thesis has investigated Near Infrared (NIR) curing, a fast thermal curing technique for polyester coil coatings used in exterior building applications where fast line speeds are required. The aim has been to further understanding of the NIR cure mechanism. UV/Vis/NIR spectroscopy and curing trials with two types of AdPhos NIR ovens were used to assess the influence of NIR absorbing pigment locus on cure. Firstly, carbon black was removed from red and brown coatings and this resulted in a wider cure window, but re-siting this pigment in the primer layer was unable to maintain coating colou

The cured coatings were exposed in a QUV A accelerated ageing test with exposure time intervals of 1200 hours and 4098 hours.

The continuous coating of steel and galvanised steel coils is referred to as coil coating. Coil coating is considered the most efficient coating method with regard to the amount of coated area per unit of time. Coil coatings include primer coating, top coating and backside coating. In general, the primer coating and top coating need to balance effectively among flexibility, adhesion, and film hardness. As such, saturated polyester resins with the capability of being molecularly engineered have found applications in coil coatings as the key binder. Nowadays, a combination of up to five polyeste
