Susterra 1,3-propanediol (1,3-PDO) is a 100% bio-renewable, biodegradable glycol that enhances wood penetration in timber treatments. It is used in vacuum pressure impregnation and wood protection additives, as it improves absorption and copper retention compared to fossil-based glycols.
Independent studies confirm higher uptake and retention with Susterra®, making it a sustainable alternative for construction timber applications.
Its low-carbon profile supports responsible production and climate action goals.
