Terpene-based latex synthesis for exterior wood protection

IRG/WP 24-20715

M Carrère, V Landry

Driven by challenges in raw material supply chains, the coatings industry is actively seeking biobased alternatives to enhance outdoor wood protection. This study aims to investigate the integration of biobased monomers into latex formulations, aligning with protocols applicable in industrial contexts. A semi-batch emulsion polymerization protocol was developed, designed to be scalable and meet essential criteria for exterior coatings, including glass transition temperature and high solids content (> 30 %). The results indicate conversion rates exceeding 91.4 % and particle sizes ranging from 40 to 51 nm. Differential scanning calorimetry was used to determine glass transition temperatures. The measured glass transition temperatures closely align with theoretical ones. These findings suggest that terpene monomers hold promising results and could contribute to the development of sustainable and industrially viable solutions for coating outdoor wood surfaces.
