Abstract
This invention concerns very high solid content aerosol adhesives and an aerosol spray device for the application of such aerosols comprising a spray can, a valve mounted to the can, a button mounted to the valve to control its opening and closing, a nozzle comprising a throughbore in fluid communication with the can interior when the valve is open. The nozzle comprises an axial throughbore, a flow restrictor being a channel having a length and a rectangularly-shaped cross section, and an exit port comprising a substantially rectangular orifice and a pair of opposing horizontal and a pair of opposing vertical walls extending and flaring outward from the orifice in the direction of the spray flow. This invention provides a very high solid content contact adhesive and an application device which provides for a substantially more uniform application of the adhesive than previously attainable.
