Why paint sticks – it’s all about the pretreatment

In a previous blog about aluminium pretreatment, I looked at how we prepare aluminium for painting, lacquering or adhesive bonding. If we want to produce an aluminium product that lasts longer than it takes for a car to roll out of a showroom or a building façade to be enjoyed for more than a few […]

polymer coatings on cans

Why polymer coatings are a necessary evil

We’ve all read recently about the scandal of plastics floating about in the rivers and oceans of the world. Of course the retail / packaging industries do themselves no favours with stories such as the cauliflower “steak” in a plastic tray covered in film. We all hate having to tear off that nasty, unnecessary packaging […]

aluminium oxide and magnesium oxide surface

Understanding your aluminium oxide surface

Back in high school we learnt that aluminium was a useful material partly because it is protected by a tenacious oxide layer. Iron, in contrast, suffers from the fact that it forms a flaky, rust layer when exposed to the atmosphere. Of course, like many truths taught at school, the aluminium oxide story only bears […]

The art and science of aluminium sculpture

This week’s blog is a little bit different. It doesn’t describe our process improvement work, or an industry development. Instead we’re going to talk about art! Specifically, we’ll look at aluminium sculpture. Over to you Colin… Aluminium sculpture at St Pancras Earlier this year I passed through St Pancras train station in London on an […]

Anodised aluminium as a catalyst support

As a technical consultancy it’s really important that we keep up to date with the latest developments in light metals. One of the ways we do this is by leading and participating in pre-competitive R&D projects. Most of the projects we have been involved with over the last 10 years have had either an automotive […]

Aluminium pretreatment – a brief overview

Approximately 40%, or 17 million tonnes, of the total world aluminium shipment is in the form of rolled products. This is used in packaging, architectural applications and transportation. All these products require modification of the surface to maintain durable performance. Surface modification of aluminium involves: Cleaning to remove residual oil, oxide films and mechanically disturbed […]
