Table 4-3 shows the typical polymer types used in metal decorating coatings, and clearly shows that acrylics are generally used as components of coatings for the outside of the container. The only internal usage of acrylic resins is in epoxy modified acrylics. These are used for DWI internal lacquers.

This is the main process used to produce the ubiquitous 2 piece beer and beverage cans which can be made out of either tinplate or aluminium. As the name implies, a metal slug is drawn from a coil and ironed to produce, in a single piece, the bottom and side of the A mechanical punching […]

by R James, PKT Oldring, PhD BA, К O’Hara LRSC and D Fone BSc (i) Introduction This sector of the industiy is very important and diverse with many specialist applications. The market is constantly changing with enormous geographic differences in the types of cans required and products packed. The past twenty-five years has seen significant […]

The OH functional acrylics in the GI metal finishing area are used mostly as one coat finishes for products intended for interior use or for products with a limited life expectancy. The coatings achieved are hard, glossy, scuff resistant but with a tendency to detach from the substrate after a blow etc. This is because […]

In the early 80’s in Europe, tractor and construction equipment sheet metal was either pretreated with iron phosphate or merely degreased, primed with an alkyd flash primer and then finished in a stoving alkyd/amino system. Application of paint was and remains, predominantly electrostatic airless spray. The performance characteristics of the paint finish were good resistance […]

Hydroxy functional acrylics are used in general industrial (GI) stoving finishes in two distinct capacities. They are used to impart highly durable finishes for exterior components such as tractor sheet metal and cabs, fenders for earth moving equipment, or as one coat finishes in more wide ranging metal finishing such as office furniture, irons, microwave […]

In the mid 1960s acrylamide functional acrylics began to dominate the domestic appliance or ‘white goods’ finishing industry, replacing alkyd/amino enamels. In particular acrylamide functional acrylics were used since they offered the best combination of hardness and chemical resistance. As organic coatings, the hardness approached that of the inorganic vitreous enamel finishes. At that time […]

Paint imperfections or mechanical damage can occur post-manufacture. Due to the many heat sensitive parts on the car, (for example, tyres, interior plastic trimmings), it is not possible to repaint the vehicle with the standard paint and subject the whole vehicle to the original curing process, which took place at 120°C or above. Special repair […]

This combination was developed by Ciba Geigy and is particularly effective in producing high durability COB automotive systems. The COB system is also used for solid colour OEM finishing. The dark, or strong colours, black, reds, greens, blues are particularly effective on cars, resulting in an increase in the DOI The principle for formulating a […]
