Abstract
Etylenglykolblanding som omfat- ter welangummi, et alkalisk sekves- treringsmiddel eller alkali, f.eks. trinatriumfosfat, og etylenglykol. Det alkaliske sekvestreringsmiddel eller alkaliet øker oppløselighet av welan- gummi i etylenglykol og øker derved viskositeten og de tiksotrope egen- skapene til etylenglykolblandingen.
