HASE Thickeners are Hydrophobically modified Alkali Swellable Emulsions which act as thickeners and antisettling agents in waterbased coatings, inks and putties. Upon neutralization to a pH typically above 8.0, HASE thickeners become active. These products are typically more cost effective to use than hydroxythethyl cellulose (HEC) thickeners.
