The present invention is directed to a delivery device and a system for introducing the catalyst into the atomized coating composition. This invention is also directed to a system for producing a mixed composition comprising two or more components.

Device for introducing catalyst into atomized coating composition

A dispensing apparatus includes recirculating systems though which the dispersants are recirculated to prevent settling of solid components, such as pigments that may be present in the dispersants. The apparatus includes dispensers located on a movable table positioned inside a frame assembly of the apparatus. The table is positioned to dispense a selected dispersant into a container placed atop a weighing scale through the dispenser selected in accordance with a recipe. The weight of the selected dispersant is monitored by the weighing scale and once a desired amount of the selected dispersant is dispensed, a signal is received by the apparatus from the weighing scale to switch off the dispensing of the dispersant. The table is then moved to deliver the next dispersant, required in the recipe. The process is continued until all the desired dispersants are dispensed in the container to form the composition, such as an automotive paint.

Dispensing apparatus

A multi-component proportioning system for dispensing a multi-component coating composition is provided. The delivery system is particularly useful in providing multi-component compositions to a multi-component dispenser. The system provides very accurate mix ratios due to the consistent, reproducible displacement of components from the liquid pump assemblies used in the multi-component proportioning system regardless of viscosity. Such accuracy eliminates improper mixing of components that can lead to reworking and lost time, materials, and profits.
