You can’t do without them when it comes to formulating coatings. They're great for selectively controlling properties. But you must fastidiously ensure that they are compatible with the other components, otherwise your high-performance coating system might quickly become lacklustre.
In an article, Indian researchers highlight some state-of-the art-modifications of vegetable oils (VEGO) as environment friendly-low or no solvent, high solids, hyperbranched, water-borne and UV curable coatings.
Theoretical calculations and experimental studies were carried out on polyurethane (PU)-TiO2 composite coatings on bright and matte aluminium surfaces with an aim to understand and tailor the light scattering from particles incorporated into an anodised layer for designing the optical appearance of anodised surfaces.
A brilliant new blue pigment – discovered serendipitously by Oregon State University (OSU) chemists in 2009 – is now reaching the marketplace, where it will be used in a wide range of coatings and plastics.
