  • POWDER COATING COMPOSITIONS COMPRISING A POLYESTER AND A FLUOROPOLYMER AND COATINGS FORMED THEREFROM
    Publication number: 20220348786
    Abstract: A powder coating composition can include: a polyester polymer having carboxylic acid functional groups; a first crosslinker reactive with the carboxylic acid functional groups of the polyester polymer; and a fluoropolymer unreactive with the polyester polymer and first crosslinker. A weight ratio of the polyester polymer to the fluoropolymer is from 80:20 to 60:40. When cured, the powder coating composition forms a single coating layer including the polyester polymer and the fluoropolymer.

  • Display tray assembly
    Patent number: 4239308
    Abstract: Pivoting trays are carried on pivot posts. The trays include a storage recess in their upper surface. When the trays are pivoted from a stowed to an open position, the contents of the trays become visible and accessible. Storage recesses are also provided in the base and top members. Compartmented inserts from the storage recess into a selectable number of compartments are carried in the trays and are removable from the trays in their opened position.
