Susterra® 1,3-propanediol (PDO), a 100% bio-renewable diol, enables viscosity reduction in medium and long oil alkyd resins by partially replacing pentaerythritol.
At 3% substitution, it delivers lower viscosity, reduced VOCs, easier emulsification, and higher-solids coatings without performance loss.
It is derived from U.S. dent corn, Susterra® reduces carbon footprint by up to 86% vs. fossil alternatives, supporting sustainable coatings innovation.
