Advances in One-component PVDF-acrylic Hybrid Dispersion and Its Applications

By Wei Wang, Diane Vaessen, Brian Peterson, Abby Miller, Arkema, Inc.

For many years, aqueous hybrid dispersions of poly(vinylidene fluoride) (PVDF) and acrylic resins have been formulated into waterborne topcoats because of their exceptional weatherability and ability to meet stringent volatile organic compound (VOC) requirements and sustainability targets. For applications requiring strong chemical resistance, hydroxy-functional PVDF-acrylic dispersions are available which allow formulators to build resistance properties with isocyanate crosslinking.
