Abstract:
Presently described are components of a spray application system, a method of making thereof, wherein at least one component comprises a liquid repellent surface layer such that the receding contact angle with water ranged from 90 degrees to 135 degrees. The liquid repellent surface (e.g. layer) may comprise a porous layer and a lubricant impregnated into pores of the porous layer; a fluoropolymer; a fluorochemical material and an organic polymeric binder; or a fluorochemical material melt additive or silicone/silane/siloxane material melt additive and a thermoplastic polymeric material component. The component is typically a liquid reservoir, a liquid reservoir liner, a lid for a liquid reservoir or liner, or a combination thereof. In some embodiments, the component comprises a thermoplastic polymeric material. In some favored embodiments, the component is a removable liquid reservoir or liner. In some favored embodiments, the component is a collapsible liquid reservoir or liner. The spray application system typically further comprises a gravity-fed spray gun.
Abstract:
A cross-linkin moiety having a structure represented by formula (I) or (II): Wherein: Ar F comprises a fluorinated phenyl group having at least one non-fluorine substituent (R) that is bulkier than fluorine and which is located at the meta position relative to the N 3 group; W comprises an electron-withdrawing group; and L comprises a linker group. The cross-linking moiety is particularly useful in the manufacture of polymer semiconductor layers and photovoltaic devices.
Abstract:
To provide a powder coating material excellent in blocking resistance and capable of forming a coating film excellent in color tone and weather resistance in which the occurrence of color unevenness is suppressed, a method for its production, and a coated article having a coating film formed from the powder coating material. The powder coating material comprises a resin powder, a luster pigment and a binder, wherein the resin powder contains a fluororesin and a non-fluororesin, the binder contains a surfactant having a melting point of at least 25°C, and the luster pigment is bonded to the particle surfaces of the resin powder via the binder.
