Application


Padding method :


Preparation of padding bath with Rubfast-467


-Take 0.3-0.6 g/l acetic acid


-To this add required quantity of Rubfast-467 (30 g/l) and mix it uniformly.


-Make the total volume with water (pH 5.8-6.2)


-Mix well to get uniform solution


-Solution of 30 g/l Rubfast-467 will appear slight hazy and turbid with pH 3.7-4.2


Pad -> Dry at 130-160 deg.C


Exhaust method

- RUBFAST-467 in Garment:


Step wise procedure for preparing Rubfast-467 solution


-Take 0.3-0.6 g/l acetic acid
