 <  Increasing wet fastness properties to highest effect levels
 < No impairment of degree of whiteness or shade
 <  Maximum process safety: a) Stable pH value in a wide range | b) High shear stability
 < Dosable in all metering devices

HYDROCOL SVN is an anionic alkylaryl sulphonate, which is used as an aftertreating agent for improving the wet fastness of dyeings and prints with acid or metal complex dyestuffs on PA-fibres or PA/WO-blends; it is extremely suitable for PA-microfibres.

Properties of HYDROCOL SVN

 < Can be directly mixed with formic acid (40%) in metering devices (resistance to acids)
 < Improves wash, perspiration, water and sea-water fastness
 < Improves the fastness to pleating and setting with dry heat
 < Stable to salt in concentrations common in dyeing
 < No impairment of the light fastness
 < Resistant to dry cleaning
 < Stable to hard water
 < Jet-stable
