Abstract
Coating applicators for applying high viscosity coatings to large area surfaces are disclosed. The coating applicators facilitate the ability to apply high viscosity materials over large areas at high speed with minimal air entrapment to provide coatings having a controlled thickness.
Claims13
An extrusion applicator, comprising:
- (a) an adaptor section comprising a proximal end, a distal end, and an adaptor channel;
- (b) a transition section mechanically coupled to the adaptor section, and comprising a proximal end and a distal end, wherein,
- the transition section defines an internal transition channel comprising a width and a height;
- the width of the transition channel increases from the transition inlet to the transition outlet;
- and
- the height of the transition channel decreases from the transition inlet to the transition outlet;
- and
- (c) a nozzle section mechanically coupled to the transition section, and comprising:
- a flow control section coupled to the transition section, wherein the flow control section comprises a plurality of parallel channels;
- a pressure control section coupled to the flow control section, wherein the pressure control section comprises a channel and one or more support structures;
- and
- a nozzle outlet in the form of a rectangular slit coupled to the pressure control section.
