Hydroxypropyl Methyl Cellulose
HPMC is a non-ionic cellulose ether produced by alkali treatment of refined cotton linters or wood pulp, followed by etherification with propylene oxide and chloromethane. Its molecular structure contains both hydroxypropyl and methoxy groups, endowing the product with excellent cold-water solubility, thermal gelation properties, and pH stability. In coatings, HPMC primarily serves as a thickener, water-retaining agent, and rheology modifier, providing a smooth application experience and a stable coating film structure.
Hydroxyethyl Methyl Cellulose
HEMC is produced by alkali treatment of cotton linters or wood pulp, followed by reaction with ethylene oxide and chloromethane. Compared to HPMC, HEMC has hydroxyethyl groups introduced into its molecular chain, which significantly enhance its hydrophilicity and dissolution rate. In coatings and construction materials, HEMC exhibits faster dispersibility, higher solution transparency, and better viscosity stability—making it particularly suitable for water-based systems that demand high transparency.
Functionally modified products
Hydrophobically Modified Hydroxyethyl Cellulose
HMHEC is a modified product in which hydrophobic long chains (such as C12–C16 alkyl groups) are incorporated into the HEMC molecular chain. This unique structure enables HMHEC to form an associative network in aqueous phases, providing remarkable shear-thinning rheological properties and excellent anti-splash performance. HMHEC is particularly well-suited for high-end coatings with stringent requirements for rheological behavior: it offers high viscosity during storage (preventing sedimentation) and a sharp drop in viscosity during application (making it easy to brush).
Hydroxyethyl cellulose ether for colorful coatings
Combizell® MP150 is a high-quality hydroxyethyl cellulose ether (HEC) developed specifically for water-based multi-color coatings. It works synergistically with protective colloids, emulsions, and other ingredients to provide excellent pigment dispersion and system stability in multi-color coatings.
Hydroxyethyl cellulose ether for coatings
Combizell® HD series HEC is a non-ionic, water-soluble polymer derived from natural cellulose. It appears as a white or slightly yellowish powder that easily disperses and dissolves in both cold and hot water, yielding solutions with varying viscosities. This product is primarily used as a rheology modifier, thickener, water-retention agent, suspending agent, binder, stabilizer, and protective colloid.
