Sarasil-JS is stable to high alkaline pH and at elevated temperature. Depending upon the requirement 0.5-1.0 g/l Sarasil-JS can be used.
Note :
1. Sarasil-JS is a surfactant free dispersion, stabilised with protective colloids and hence its dispersions appears non-homogeneous. However, such products should ideally not diluted to stock solutions, but diluted immediately before use.
2. For preparing stock solution small quantity of Xanthan gum (0.3-0.4% on weight of stock solution) or synthetic thickener is recommended.
3. Sarasil-JS is not advisable to use in high temperature /high pressure machines and hence cannot be used in polyester dyeing.
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.
Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
