Method of dispensing a material
09772059 · 2017-09-26 · ·

A method and system for dispensing a material through a delivery apparatus is provided. The material initially comprises or is manipulated to comprise a low viscosity. The material either can comprise a curable material or can comprise initiators, which can be activated to raise the viscosity at a later time and position. The low viscosity material is moved through the delivery apparatus for a relatively long distance using low energy. Upon nearing an end use application, the material and/or initiators can be activated by a curing agent, such as a light or heat source, such that the viscosity of the material be raised prior to the end use application thereof. Therefore, the present invention provides a method and system for moving a material normally having a higher viscosity a long distance requiring lower energy and pressure.
