Evaluation of bio-based products in architectural paints

This study considers the incorporation of bio-based products in the formulations of architectural paints. The first part focuses on the use of alkyl-polyglucosides and of alkyl-polypentosides as dispersing agents. Compared to conventional petrochemical components these sugar-based additives present several advantages such as being non-toxic, biodegradable, odorless and non-irritating. In this paper their influence on the properties of coatings is evaluated and their performances are compared with those of reference petrochemical additives. The second part is dedicated to the use of gluten as co-binder or as additive in architectural paints. Gluten represents approximately 80% of the proteins contained in cereal and is widely available.
