CONVERTING TO WATERBORNES

摘要

Just as government regulations concerning gasoline mileage in the '70s helped spur today's improved automobile engines, so government regulations concerning VOC emissions from coating lines have spurred the development of some remarkable waterborne and water-based coating materials. Now manufacturers need to know how to convert their operations to use these new materials efficiently. This means that they need to know what application equipment is suitable and how best to use it to apply waterbornes. A likely first question is "What is the best way to apply a waterborne material?" The answer is "There is no best way." The process that works best in a particular application with a solvent-based coating will usually continue to be the best after converting the application to a waterborne coating. The dynamics of getting material from the applicator to the part are similar whether the material contains mostly solvents or mostly water.
