Waterborne coatings increasingly require alternatives to traditional glycols due to VOC constraints and usability demands. Substituting propylene glycol or butyl glycol with Susterra® 1,3-propanediol extends open time while preserving drying behavior, gloss, hardness, and adhesion.
Evaluation in polyurethane wood coatings confirms improved film formation, formulation flexibility, and potential reduction in rheology modifiers.
