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....

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....

In this technical paper recent developments in additives for use in parquet floor coatings are discussed. A siloxane has been introduced with both substrate wetting and defoaming properties, “wax alloys” and hard nanoparticles enhance scratch resistance, while a new dispersant assists in matting high solids coatings with silica. Tests on UV primers identified adhesion differences between wood species and some specific causes of adhesion problems....

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

Intumescent coatings provide a highly effective means of protecting substrates from fire damage. All these coatings undergo a similar series of reactions in a fire, creating an insulating foam many times thicker than the original coating. They are commonly applied to steel and wood substrates, but other application areas include electrical cables, textiles and intumescent gel coats for composites....
