Weldable PVDF may include up to 70% acrylic resin with the balance being PVDF resin, modifiers and a carrier. Since the acrylic resin is the major polymer in the system, the properties inherent of acrylic polymers result in the degradation of the surface coating system. In addition, studies have shown that at the low PVDF content, mechanical properties – tensile, impact, and overall durability are sacrificed due to disruption of the crystallinity of the molecular structure.
