Tips For Proper Usage Of UF2 Grade ASACLEAN

    • For maximum performance, ASACLEAN should not be diluted with other materials.
    • ASACLEAN does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge.
    • ASACLEAN works best with maximum agitation – use the maximum safe screw speed and, for thermoplastic injection molding, also use maximum safe back pressure with the screw in the most forward position. (Mechanical Purge Grades)
