Priplast™ F4
Priplast™ F4 polyester polyol combines the hardness of high functionality polyols with the flexibility of dimer-based technology. It can be used alone or as a co-polyol in PU resin applications, such as high solids 2K coatings, to enhance properties like chemical resistance and drying time.
Additionally, it offers excellent chemical and moisture resistance, protecting sealants from moisture damage.
Priplast F4 is 59% bio-based*, USDA Bio-Preferred certified*, and ISCC PLUS certified.
