  • One tank paint makeup process using a recirculation loop with liquid injection
    Patent number: 5590960
    Abstract: Paint compositions useful for automotive applications are made using a one tank process with an associated circulation loop. Addition ports located in close proximity to a zone of high speed mixing allows for rapid blending of materials into the process stream. A bypass subloop connected to the circulation loop will divert paint to grinding apparatus achieve addition of pigments on-line. Instrumentation attached to the circulation loop directly measures the process stream parameters such as viscosity, pH, temperature, and pressure.
