HEC-liuoksilla on pseudoplastiset reologiset ominaisuudet (leikkausohennus). T\u00e4m\u00e4 tarkoittaa sit\u00e4, ett\u00e4 varastoitaessa ja suuressa leikkauksessa (esim. sekoittaminen, pumppaus) viskositeetti on alhainen, jolloin sit\u00e4 on helppo k\u00e4sitell\u00e4 ja kuljettaa.<\/p>

Kun leikkaus on pieni (esim. kun puristin kulkee painoseulan yli ja lep\u00e4\u00e4 kankaan p\u00e4\u00e4ll\u00e4), viskositeetti palautuu nopeasti korkeammalle tasolle.
