  • Low-gloss paints including polyvinylidene fluoride having a high melt viscosity
    Patent number: 6281280
    Abstract: A paint composition which comprises a binder component which includes a polyvinylidene fluoride polymer and a solvent component. The polyvinylidene fluoride polymer has a melt viscosity of at least 40 kPoise. Such paint compositions have low gloss and are useful as exterior weather-resistant paints for buildings where low-gloss paints are preferred.

  • Compatible polyvinylidene fluoride blends with polymers containing imide moieties
    Patent number: 5959022
    Abstract: A compatible blend of superior mechanical strength, hardness and abrasion or mar resistance comprising PVDF and a compatible organic polymer containing one or more imide groups. The alloy consisting of PVDF and a polymer containing imide groups is prepared by dissolving, separately, the PVDF and polymer in a solvent and blending the solutions to provide the required composition. The alloy can also be prepared by dispersing PVDF powder in a solution of polymer containing imide groups. After heating and drying, a homogeneous alloy is formed. In addition, melt extrusion of PVDF with the imide-containing polymer also generates the desired PVDF alloy.
