Evaluation of bio-based products in architectural paints

International audienceThis 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

Evaluation of bio-based additives in architectural paints

International audienceThe use of bio-based products (i.e. non-food products derived from biomass) in numerous industrial applications is currently arousing increasing interest. The industry is faced with two main challenges with regard to the use of these raw materials in paints. First, only a limited range of bio-based products is acceptable in terms of quality, cost and availability for this application. Second, there is a general lack of information about these products
