Cup and Collars Support Liners3M PPS Cup & Collar is a component set used with the 3M Paint Preparation System (PPS). This set includes two hard plastic cups and two collars that provide support for 3M PPS flexible liners.Advantages of the 3M PPS SystemUnlike conventional paint cup systems, our 3M PPS eliminates the need for mixing paint in additional paint mix cups and then transferring the paint through a separate filter into a paint reservoir. This is an important advantage because product waste occurs every time that an auto body technician transfers paint through mixing cups and filters. With PPS, you place the disposable liner within the re-usable PPS Cup. Then simply mix the paint in the PPS disposable liner, snap the disposable lid (with the pre-welded filter) in place and attach the locking collar to complete the PPS System. With just these few simple steps, you're ready to start spraying.Your spray gun functions at any angle, even upside downPPS allows the painter to spray consistently 90 to the part, no matter how the part is positioned. This makes material transfer more consistent, limits paint overspray and lowers paint consumption. With conventional systems, many painters mix more paint than necessary to reduce the chance of starving the gun, which results in wasted paint when it's time to clean up. Our PPS eliminates the urge to mix more paint than needed because "starving the gun" is simply not a problem.Clean Up is a Breeze and Uses Less SolventAfter spraying, the painter has a choice of either using a sealing plug to temporarily store non-catalyzed paint materials or to clean up. The liner, lid and built-in filter are all disposable, leaving only the adapter and spray gun to be cleaned. Simply throw the disposable lid and liner in the appropriate approved waste containers specified by the paint manufacturer (or local government requirements) and use a small amount of solvent for cleaning the spray gun and the PPS adapter. It is possible to clean your paint gun with as little as 3 fluid ounces (90mL) of solvent. With this disposable paint system, shops are often experiencing up to a 70% reduction in cleaning solvents, which can translate into cleaning solvent savings, solvent disposal savings and less operator exposure to solvents.
