Abstract
Methods and systems for coating with shear and moisture sensitive materials are disclosed. A method of coating a product includes filling an inner bellows chamber of a bellows, which is provided within and isolated from an outer bellows chamber of a tank, with a predetermined amount of the coating material. The method of coating the product further includes supplying a pressurized material to the outer bellows chamber to pressurize the coating material within the inner bellows chamber to an operating pressure, and supplying the coating material within the inner bellows chamber to a spray gun at the operating pressure. The method of coating also includes determining that a measured actual pressure is within a predetermined control range of the target pressure and subsequently coating the product by spraying the product with the coating material from the spray gun.
