Methyl hydroxyethyl cellulose (MHEC) is a white, odorless powder. CAS NO: 9032-42-2. Hydroxyethyl methyl cellulose (HEMC) can thicken, suspend, agglutinate, float, and provide protective colloid, for this reason, it is mainly used as an adhesive, thickener, and emulsifying additive. Hydroxyethyl methylcellulose is a high-efficiency water retention agent because its aqueous solution has good hydrophilicity. MHEC has a good anti-mildew ability because it contains hydroxyethyl groups. It has good viscosity stability and anti-mildew degeneration during long-term storage. Kingsun MHEC has a good performance in coatings and building materials. It has stronger water retention than methylcellulose, stronger viscosity stability, mildew resistance, and dispersion than hydroxyethyl cellulose.
