A newly introduced neutralising amine for waterborne coatings, secondary-butyl ethanolamine or sBEA, has an amphiphilic structure, through which it can assist dispersants in separating and binding to pigment particles. Tests on a blue tinting base show that sBEA provides greater pigment efficiency and better flow properties than classical amines such as DMEA....

Control over protein adsorption and cell adhesion is necessary in technical processes such as water treatment, as well as high-end and academic applications such as bioanalytics or tissue engineering. Coatings prepared from end-functionalised six armed poly(ethylene oxide) based star molecules are shown to be highly effective for a range of biomedical applications

At present, only complex research instruments can accurately characterise the appearance of effect coatings. A new multi-angle portable spectrophotometer incorporates detectors which are out of the plane of illumination and reflection. This complex data is simplified mathematically, so that overall colour tolerance limits can be set which take into account the appearance of a coating from all angles....

A European consortium known as Multiprotect has developed a range of nanoparticle-based corrosion protection systems in an attempt to replace both chromate pretreatments and hard chrome coatings. Various types of coating showed enhanced salt spray resistance and in some cases self-healing properties. Some systems have been applied successfully under industrial conditions....
