Graco (North Canton, OH, US) has launched its RS chop gun for the flexible and precise application of fiber-reinforced plastic (FRP) in the marine and other markets. This 13:1 chop system proportioner is said to offer precise on-ratio dispensing with easy transition from wet-out to chop. The system is designed such that no surge bottle is necessary and a low amount of solvent and resin is needed to prime the pump, so material costs are kept low. It also features include a dual trigger function, allowing operators to change from wet-out to chop without turning the chopper off. Additionally, the gun has what Graco says is a uniquely designed blade cartridge, with blades molded directly into the cartridge. Operators can change blades without touching individual blades and without use of a special tool, thereby increasing operator safety and making it possible to change blades in less than a minute.
