| dc.description | In recent years an increasing interest is observed in the development of more enviroment-fiendly paints and coatings. This paper discusses advances in the use of renewable resources in formulation for various types of coatings. In particular, recent developments in the application of (new) vegetable oils and plant protein in coating systems are addressed.Regarding vegetable-oil-based binders, current research is focussed on an increased application of oils from conventional as well as new oilseed crops. A very interesting new vegetable oil, for example, originates from such crops as Euphorbia lagscae and Vermonia galamensis, which have high contents (60%) of an epoxy fatty acid (9c,12,13 epoxy-octadecenoic acid or verlonic acid) that can be ised as reactive diluent. Another interesting new oils is derived from Calendula officinalis, or Marigold. This oil contains 63% of a C18 conjugated tri-ene fatty acid (8t,10t,12c-octadecatrienoic acid or calendic acid), analogous to the major fatty acid in tung oil. Presently, reseach aims at evaluating film-forming abilities of these oils and of chemical derivatives of these oils, both in solvent-borne and water-based emulsion ystems. In research on industrial applications of plant proteins, corn, but particularly wheat gluten has been modified chemically to obtain protein disoersuiba that have excellent film-forming characteristics and strong adhesion to various surfaces. Especially wheat gluteb films have very interesting mechanical properties, such as an extensibility of over 600%. Gas and moisture permeabilities were found to be easily adjunstable by changing the exact formulation of the protein dispersion. Durability and water-resistance of the coatings can be tailored by, e.g., varying the degree of corss-linking of the protein binder. | |
