A sustainable life for the "inhabitants" of the sea - that's the overall goal of the "Marine Paint" research program. This project, carried out at the University of Gothenburg and Chalmers University of Technology in Sweden, is aimed at developing new and effective marine antifouling paints, which are more environmentally friendly than those in use today.
At the moment my days are filled with preparations for the European Coatings SHOW (ECS) 2011. More than 170 papers have been submitted for the European Coatings CONGRESS wich will run concurrently to the ECS. Out of these papers the program committee has to select 108 papers for the CONGRESS. I'm wondering what will be the trends this time. We received many papers dealing with environmentally friendly and sustainable coatings. Biobased raw materials will also play an important role in the congress program as well as "traditional" topics such as protective coatings and polyurethanes. What do you think will be the main trends at the ECS 2011?
It is an undisputable fact that decorative paint markets are being tilted more towards growth in the decorative DIY segment, rather than the professional or construction segment. More than ever this segment seems to be driven by environmental awareness. Legislation continues to push decorative paints towards low-, if not no-VOC formulations. This prompted IRL to conduct a survey of the greening of the decorative coatings sector. Asked about their business strategy paint makers indicated that the current standing of the industry is that about 70% of decorative paint makers in Western Europe produce...
Nowadays coatings have to be environmentally friendly otherwise it is hard to get a product accepted by the market. Improving the environmental profile of new products is a large driver in coatings development. Formulating waterborne systems is one option to reduce the VOC level and to make a system more environmentally friendly. However, dispersing pigments is rather challenging in such systems - foam generation is another nuisance. The use of the right additives helps to face these challenges. However you need to find the perfect mix. Would you change that system if there would be an one in all additive available?
I was talking to some experts of the printing inks industry the other day. They unanimously told me that due to the economic crisis there are hardly any technical developments going on at the moment, neither regarding raw materials nor processing technologies for printing inks. Companies are basically trying to reduce costs and increase efficiency. Among the challenges facing the industry are rising raw material prices, availability of raw materials, regulation and sustainability issues.
No doubt, formulating high perfoming VOC 2010 compliant paints and coatings has been a real challenge. When the first waterborne near-zero VOC coatings was presented this marked a real breakthrough in coatings technology. What will be the next?

In our editor's blog smart coatings are a frequently recurring topic. We have described exciting functional coatings, we have asked how "smart" these coatings really are, and we have been wondering how smart coatings can be defined after all. I guess it's best to say smart coatings are structured coatings which provide additional benefits by giving an appropriate response to outside conditions.
In order to obtain a high performing coating efficient and effective pigment dispersion is in gerneral indispensible. Long-term stabilisation of the dispersed pigments is a key-factor. However, the permament breaking down of agglomerates into, as far as possible, primary particles is cost- and time intensive. Now, a student developed in his diploma-thesis an aftertreatment for pigment surfaces making the conventional dispersion nearly dispensable.
With an impressive number of 140 participants, the Coatings Science International (CoSi) conference 2010 took place in Noordwijk last week. The beautiful Dutch North Sea resort was again the venue for this gathering of international coatings experts. 32 lectures were given on latest research findings in the field of coatings.
