SARASOL-GP |

Pre-treatment for Digital Printing of Cellulose

Product Information

Sarasol-GP is a high viscosity thickening agent which is applied in pre-treatment process of Ink-Jet printing. Sarasol-GP gives sharp and even prints with improved colour values especially on cellulosic substrates. It also delivers even and sharp prints on the substrates printed with disperse and acid dyes. Sarasol-GP does not affect the original hand of fabric. The quality of final print obtained with Sarasol-GP is much better than that obtained with conventional thickeners.

Note:

  1. 1. Sarasol-GP can be applied by coating with 50% diluted product. 
  2. Concentration of Sarakol-NF to be added depending on GSM of fabric. For lower GSM fabric, lesser quantity of Sarakol-NF is required compared to higher GSM fabric.
Precautions

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.
