Maylis Carrère, a PhD student in wood and bio-based materials engineering under the supervision of Véronic Landry, had the opportunity to take part in the prestigious “ABRAFATI International Coatings Congress”, held from November 21 to 23, 2023 in São Paulo, Brazil. Her involvement in this major event in the field enabled her to present her innovative research project entitled « Waterborne coatings for outdoor wood products with terpene derived monomers ».
This opportunity enabled Maylis to share her discoveries and scientific advances with an international audience of peers and industry professionals through an oral presentation on « Biobased Latex for Exterior Wood Coatings », thus broadening her areas of expertise and networks of contacts. Thanks to the generous support of the CRMR’s student mobility program, as well as CIRCERB and Université Laval’s international office, Maylis was able to make this exceptional experience a reality. This financial support was essential to enable Maylis to represent her institution and actively contribute to the advancement of research in her field.
Congratulations to Maylis on this achievement, and we wish her every success and prosperity in her academic and professional career!
Presentation title and summary: Bio-based latex for exterior wood coating
Wood is a natural material with many interesting physical and mechanical properties, such as resistance to thermal change and insulating ability, making it suitable for use as a building material. In the building sector, it is used in particular as exterior siding. Wood can however be weakened by weather conditions and by micro-organisms.To maintain their properties and aesthetics, exterior wood surfaces are usually protected by a coating. Water-based coatings are most often prepared using emulsion polymerization technology. Until now, most latexes have been prepared from petrochemical products (e.g., acrylate monomers). To reduce the environmental impact of these coatings, the use of biobased raw materials is considered. The main objective of this project is to develop a coating for outdoor wood based on local biobased raw materials. Wood extractives will be functionalized with acrylate groups and then polymerized by emulsion polymerization. Glass transition temperature and particle size of latex particles were determined using differential scanning calorimetry (DSC) and dynamic light scattering.The integration of the acrylated biobased monomers was confirmed using chromatography.
