DHK8988 is a rotary screen printing thickener composed of a kind of polyacrylic acid ester, with very good self-thickening ability, suited for the pigment printing of cellulosic fibre and its blends.
PROPERTIES AND ADVANTAGES
Storng resistance to electrolytes, fast thickening speed, high colour paste stability.
High strength, small dosage, negligible influence to handle.
Sharp definition, dark colour yield, good brilliancy.
No influence to shade in pigment printing, good colour stability.
Formaldehyde free.
