Abstract: An aerosol sprayhead assembly which includes a restriction between a sprayhead inlet communicating with an aerosol container and a nozzle opening which produces a fan-shaped spray pattern. The restriction acts in cooperation with the nozzle opening to provide a more uniform spray than may be achieved using an otherwise identical sprayhead which does not include the restriction. In one embodiment of the invention, the restriction defines an orifice formed as part of the sprayhead. In another embodiment, the restriction defines a single orifice or a plurality of orifices located within an outlet tube terminating in the nozzle opening. In a further embodiment of the invention, the restriction defines an integral reduced cross-section portion of the outlet tube.

Abstract: A non-glare, abrasion resistant coating can be produced by spraying a polymerizable composition onto a surface. The composition comprises an epoxy prepolymer of an epoxy-terminated silane and an oxirane comonomer in solution. The composition may be conveniently applied from an aerosol can.
