ProMix delivers 2K water-based coatings for an automotive supplier
An industrial plastic and automotive supplier for PSA had an old painting plant consisting of a robot and old competitive 2K equipment that used gear pumps and old spray guns. The system could not produce the newly, customer approved 2K water-based materials, mostly due to an isocyanate B component. A whole new paint supply system was needed with a new 2K machine which could handle and process two colours.
Due to the isocyanate B component and the mixed high viscosity, Paint Service supplied a ProMix™ 2KE piston pump unit with a complete paint delivery system installed with AirPro™ EFX automatic spray guns on robots. Paint Service installed a completely new pressurized air valve box to feed the paint robot. Colour changes are carried out via the special valve system.
The end-user found the system accurate in handling the 2K water-based coating. The EFX spray guns were compact and simple to install and the spray pattern certificate delivered with the guns proved to be extremely useful.
- The installation of the 3:1 piston pumps provided a big opportunity.
- The unit proved to be reliable with isocyanate B components.
- The AirPro EFX spray guns provided a good spray pattern and surface quality.
- The new air valve box installed by Paint Service proved to be very precise.
- The installation provided decreased solvent usage and VOC emissions.
