Alongside the development of improved coatings, improved testing methods have emerged, whose usefulness ranges from vital necessity to 'solutions in search of a problem to solve'. Some of the technologies to emerge in recent years and some light which has been shed on correlating tests to the real world are reviewed in this month's Frontiers column...

From simple beginnings in the 1950s, powder coatings have developed into a well-established sector, holding about 8-10% of the industrial coatings market in most regions, but (according to market researchers IRL) close to 13% in Europe...

In the editorial Rheology Part 1, rheological aspects of coating systems were described. Coating properties influenced by rheological additives were categorized. In table 1.1 this categorization is once more provided. The selection of water based rheological additives (thickeners) was described in article Rheology Part 2. In this article the selection of solvent based rheological additives for each sub category, is further discussed...

This month's 'Frontiers' technology review considers some of the problems, solutions and specific markets for coatings applied to thermoplastics. The majority of plastics are used in short-term, low-cost, low-technology or purely practical applications and are uncoloured or bulk-coloured, but coatings may be applied for many different reasons...

The use of toxic materials in coatings has a history as long as the use of the word 'improved'. How could natural oils be made to dry faster, provide corrosion resistance, high whiteness and so on? Some of the earliest and simplest solutions were to use lead-based additives...

The recent Ipex exhibition at Birmingham's NEC provided an admirable showcase for all that's best, most recent and most interesting in print technology, but the key reality which every printer, ink maker, machinery manufacturer and print buyer must face is: what does the market demand?

Nanotechnology has become a fashionable term in industry; researchers are quietly advised to rebrand their projects as nanotech whenever possible so as to access Government funding, and only unjustified bad publicity has protected us from seeing it in the supermarket as an excuse to raise prices...

Fluoropolymers and silicones are hugely useful in coatings and many other areas of industry, conferring unique surface and bulk properties, high resistance to damage, low surface energies, thermal resistance, unusual optical properties … the list of thing we cannot do readily without them is almost endless. An attempt has been made to illustrate their versatility in the coatings industry in the diagram - but this makes no reference to their many other specialised uses.

Coatings are designed to protect and defend their substrates, and the coatings industry has a remarkable history of being able to achieve this more and more effectively, despite the turning screw of legislation.

Under the pressure of environmental regulations, the coatings industry has moved a long way from the brute-force approach of using toxic lead and chrome pigments to protect metal structures. Alongside established barrier pigments and the development of an ever-widening range of low-toxicity active anticorrosives, what once seemed the paradoxical approach of using rust-promoting water as the main solvent in anticorrosive coatings is increasing in scope, reaching even into the demanding areas of aerospace and offshore coatings.

Architectural coatings form the outer ‘skin’ of buildings made from many materials, and like human skin they must often resist rain and environmental contamination, while allowing internal moisture to escape. Modern architectural finishes are increasingly able to meet that challenge, where once the choice lay between impermeable solvent-borne coatings and too permeable waterborne ones...

With the adoption and implementation of VOC (volatile organic compounds) regulations, the coatings industry in the United States has changed significantly over the last thirty years. As pollution laws have evolved in other industrialized countries, similar changes have come about. The developers of standards, chemical suppliers and manufacturers should be applauded for meeting lower emission standards, though reluctantly at times. The progress in reducing VOC has been staggering. If someone had forecast today’s VOC standards thirty years ago, very few would have expected the industry achieving current standards.

Until 'nanotechnology' appeared on the scene to steal headlines (and research grants) dendrimers and their less disciplined relatives, hyperbranched polymers, were among the most talked-about developments in coatings research. Though some types are commercially available, commercial development is proving much slower than initial optimism predicted. Still, new ideas and applications are continuing to emerge, problems found with the earlier types are being resolved, and in the long run, they should transform the properties of radcure coatings in demanding applications.

Digital printing: you know it’s a convenient catchphrase, you know it’s eating into the market share of conventional printing, but what does the term actually mean? "A word means just what I choose it to mean, neither more nor less" said Humpty Dumpty in Lewis Carroll’s Alice Through the Looking Glass. And that’s the way the manufacturers of printing presses use the word ‘digital’...

Wood is all around us – sometimes disguised so that we do not recognise it, sometimes on the other hand as something looking like wood when it is not. Inside our homes, up to half of all furniture surfaces are now covered with some form of ‘synthetic’ finish such as laminates, melamine or PVC foils, but those can be applied to wood composites and may also attempt to present the appearance of wood...

The main issues which keep automotive paintmakers awake at night can be described as the four Cs: Cost, Corrosion, Compliance with legislation and Cosmetics.

'Necessity is the mother of invention' says an old proverb; so let's take a look at some recent innovations in radiation curing which were born to satisfy unusual necessities. Cellular or lattice-structured solids can be useful in biomedical applications, but complex 3-D structures like this cannot be produced by machining...
