REATHICK-PDR | Sodium alginate substitute for Reactive printing on cellulosic substrates

Product Information

Reathick-PDR is a sodium alginate substitute for Reactive printing on cellulosic substrates. Reathick-PDR exhibit prints with high brightness, high brilliance and high permeability. Reathick-PDR has excellent permeabiity with uniform colour yield. It gives much better and cleaner print than sodium alginate. It is suitable for both, Flat and Rotary screen printing.

- Take the reactive dyes as per recipe.

- Dissolve in water adding Urea and resist salt.

- Then slowly add Reathick-PDR to get desired viscosity.

- Add sodium bicarbonate just before printing and if required, adjust viscosity with addition of small quantity of Reathick-PDR.

Note :

The dosages of thickener and auxiliaries can be adjusted.


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.
