FOCUS release procedures triggered by pH activation of the permeable polyelectrolyte shell. A lengthy section of this paper is devoted to describing the emulsion route to preparing containers by both chemical and physical methods, followed by solvent extraction and evaporation to begin the process of interfacial precipitation, which is the beginning of the shell formation. The nanocontainers are completed by formation of solid shell/liquid core or compact morphology. Interfacial polyaddition by physical methods produces a range of containers designated inhibitor I (inh I) while those produced by chemical methods are designated inhibitor II (inh II). Examples are shown in photographs of coatings with and without containers incorporated in an epoxy based powder coating. These show the distribution and functionalities of both Halloysite nanotubes and silica nanocontainers dispersed in a clear powder coating applied to metal panels. There are also photographs of powder coated aluminium alloy and steel panels showing the results of long term salt spray testing, using inh I and inh II modifications and a control panel. The paper concludes that the incorporation of active agent filled nano- or microcontainers improves the resistance of the coating to various environmental conditions. The type of microcontainer also determines the efficiency of the coating. It is also claimed that the use of different active agents, such as sealants and biocides, could be a future technique for providing active coatings with specific functionalities or multifunctional properties.

AkzoNobel writes off €3.6 bn from paint operations AkzoNobel has written off billions of Euros from its paint operations. In 1999 the company recorded a €1.2 bn write off and analysts believe that virtually all goodwill for the decorative paints division had now been written off. This casts a shadow on the acquisition of ICI for around €13 bn in 2008 which made AkzoNobel the world’s largest paint company. On 18 Oct 2012 AkzoNobel
