The reason why HEC popular in surface finishes?

Widely used cellulose ethers in films consist of methylcellulose (MC), hydroxyethylcellulose (HEC) and hydroxypropylmethylcellulose (HPMC). These water-soluble polymers have different compound alterations and attributes, but all have thickening and stabilizing results. Among them, hydroxyethyl cellulose is among the most widely employed thickeners from the layer sector. Hydroxyethylcellulose is produced by reacting cellulose with ethylene oxide, which grafts hydroxyethyl groupings onto the cellulose backbone. The amount of substitution (DS) and molecular weight of hydroxyethylcellulose can be diverse to produce merchandise with assorted thickening productivity and rheological qualities.
