E WET OH
Wetting Agent for Lye Treatment of Warp Yarns
Promotes instant wetting of yarn during caustification.Enables the yarn to reach more deeper/shades. Hues is more uniform and solid.Stable between 5 15 Be'.Anionic/Nonionic.Silicone free.
RecipeNaOH 8 12 Be'
E WET OH 5 10 ml/LEXOLINE PAD 8 10
EXOLINE PAD
Pick-up Enhancer for Padding Systems
Polymer emulsion.Increase pick-up in padders on hydrophobic and/or tightly woven fabrics. (e.g.)
Desizing,Caustification of denim dyeing,CPB dyeing.
EXOLINE PAD is used with wetting agent together to achieve synergestic boom.
E WET MRS
Wetting Agent for Mercerising and Caustic Treatment
Sulphated alcohol.Anionic.E WET MRS is highly active, low foaming for alkaline scouring and mercerizingprocesses.E WET MRS has its best wetting effect in caustic soda of 15 - 30 Be'.

EVULATION
E WET NDGWetting and Penetrating agent for Indigo Dyeing
Salt of phosphoric acid ester.Anionic.It is a low foaming padding auxiliary for sulphur and reactive dyeing andensures uniform pick-up on the width of fabric or rope yarns.E WET NDG is stable up to NaOH, fl 25 g/L (4Be' Caustic soda)E WET NDG improves reproducibility of dyeings.
E WET ESC
Nonionic Wetting Agent for Padding of Cationic Resins and Softeners
Mixture of surfactants.Nonionic.
E WET ESC is specially developed to apply cationic chemicals, like silicone and fattyacid softeners.E WET ESC is a strong penetrator and ensures thourough and uniform pick-up inpad applications.E WET ESC is an efficient deaerator. It may applicable in beam, package or exhaustdyeing.
