摘要

A system for spraying an aqueous composition, the system comprising: a container (11) having an inner wall (15) and at least one entry port; a valve (19) connected to the entry port, wherein the container (11) and valve (19) are adapted to contain pressurized materials within the container (11); an inner layer (17) that is resistant to corrosion from contact with water, wherein the inner layer (17) is in contact with, and at least substantially covers, the inner wall (15); an aqueous composition (13); and, at least one propellant, wherein the aqueous composition (13) and the propellant are each disposed within the container (11) and are in contact with each other.
