PROPERTIES & USES:

  1. AVCOPRINT ABZ can be used with all types of aqueous pigment concentrates.
    Nonionic pigment preparations such as AVCOLOR PIGMENT range are preferred.
  2. AVCOPRINT ABZ is suitable for printing on all types of absorbent textile fabrics.
    Only fabrics that can stand hot curing process at 150°C for at least 3 minutes
    should be used.
  3. AVCOPRINT ABZ is suitable for printing with all types of rotary and flat bed
    printing machines, even with very fine mesh screens.
  4. Prints are soft, and when properly cured, the fastness properties are good.
  5. AVCOPRINT ABZ contains a re-dispersible binder, which has no tendency to clog screens,
    even in long printing runs.

APPLICATION:

  1. Add to AVCOPRINT ABZ the needed amount of the pigment concentrate. Concentration of pigment should not be above 5-6% when using European standard pigment concentrates.
  2. Mix pigments in the printing paste with an high speed homogenizing mixer, until all pigment is very well dispersed in the paste. Sieve through a very fine mesh screen.
  3. Print, dry and cure for 3-5 minutes at 150°C, It is possible to shorten curing time by increasing the temperature. Curing at 180°C for 1-2 minutes is enough. Hot pressing can be sufficient, but results should be evaluated carefully.
  4. For increasing paste viscosity add 0.25 – 0.50% AVCOCLEAR NP.
  5. For lowering viscosity add up to 10% of water, or add a solution of common salt or ammonium salt (very small quantities are needed: 0.5-2 g/kg).
  6. For improving wash fastness, when printing on synthetic fabrics add 0.5-1% AVCO-PRINTFIX L.
  7. After printing, screens should be washed and dried in the normal procedure. During long stoppage in the printing process, screens should be wrapped with a wet rug, or should be removed from the machine for cleaning and drying, before further used.
  8. Residues of coloured pastes can be mixed for reusing in any desired colour recipe. When residue of AVCOPRINT ABZ is stored for long time, the product should be kept in tightly closed drum.
    Before reusing the paste should be re-homogenized and filtered.
