Biorenewable raw materials have been widely used in coatings for a very long time, for instance in natural oil-based or alkyd coatings. In these, fatty acids, such as those derived from linseed oil, are polymerised by reacting polyols with polyacids via polycondensation. In the past alkyd resins were solvent-based : in recent years water-borne alternatives have been developed. Although the gloss and appearance of this type of resins is excellent, water-borne alkyd resins do come with some shortcomings, such as dark yellowing and a relatively slow drying process compared to, for instance, polyacrylate- or polyurethane-based coatings.

(Meth)acrylic copolymer emulsions for use in coatings containing plant-based monomers / Tijs Nabuurs in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 208, N° 4645 (10/2018)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 208, N° 4645 (10/2018) . - p. 7-10 Titre : (Meth)acrylic copolymer emulsions for use in coatings containing plant-based monomers Type de document : texte imprimé Auteurs : Tijs Nabuurs, Auteur ; Maud Kastelijn, Auteur Année de publication : 2018 Article en page(s) : p. 7-10 Note générale : Bibliogr.

Most promising types include the diesters of itaconic acid and esters of (meth)acrylate monomers prepared with plant-based alcohols. Other plant-based monomers show issues with either too slow, or too high reactivity, or with lacking commercial availability. Applying the preferred and commercial available monomers in emulsion polymerisation can yield water-based and partially plant-based binders showing film properties in industrial coatings that are similar to those found for paints based on commercially available fossil-fuel based binders. At this point in time, polymeric binders with plant-based contents of around 40% can be achieved (calculated on total carbon content). New developments with even higher plant-based contents are, however, foreseen to be available within five years from now. Note de contenu : - Table 1.

Morphology control in water-based biorenewable binders for decorative paints / Tijs Nabuurs in SURFACE COATINGS INTERNATIONAL, Vol. 104.3 (05-06/2021)

In this paper, the process of developing a biobased binder with a very interesting combination of mechanical properties, excellent water resistance and water absorption is described. Achieving a heterogenous particle morphology proved to be essential for achieving a good set of mechanical properties in these coatings. Effective phase separation between very - and equally - hydrophobic copolymer hard and soft domains can be realised by using significantly different acid concentrations in the two phases. The use of 1% acrylic acid in the soft phase and 5% in the high Tg phase resulted in a copolymer emulsion, which when cast into a film gave a film morphology of a soft matrix with high Tg protrusions. Applying this finding in an emulsion polymer containing 2-octyl acrylate and isobornyl methacrylate as the prime biobased monomers, resulted in a copolymer emulsion with a biobased content of 30%, based on 14C concentration, and a solids content of 49%. Surface hardness and blocking resistance were significantly increased, while the excellent elongation at break was not negatively compromised. Due to the more hydrophobic composition, the water resistance and water absorption properties were significantly better than those of the fossil fuel-based reference. The carbon footprint (CFP) of the thus-formed biobased resin is 17.2% lower than the fossil fuel-based reference, when compared conservatively, not considering the higher solid content of the biobased version.

Novel, water-based fluorinated polymers with excellent antigraffiti properties / Jurgen Scheerder in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 2, N° 8 (10/2005)

The synthesis of the binders and the surface and bulk properties of their coatings are discussed. The surface properties of these coatings are characterized in terms of their surface-free energy, as calculated from static contact angle measurements. The distribution of the fluorine atoms throughout the coating is measured by X-ray photoelectron spectroscopy (XPS). The bulk properties are studied by determining the crosslink density through dynamic mechanical thermal analysis (DMTA), and the effect of the crosslinking conditions on the crosslink density and the antigraffiti properties is discussed. The results indicate that a combined action of surface and bulk properties gives these coatings their excellent antigraffiti properties. The applicability of these polymers as protective coatings for metal and concrete surfaces are demonstrated.
