Construction Use Cellulose Ether HEMC MHEC for Concrete Admixture

QingQuan Cellulose supplies Hydroxyethyl Methyl Cellulose (HEMC) and Methyl Hydroxyethyl Cellulose (MHEC) for construction applications, including concrete admixtures. These cellulose ethers improve water retention, workability, and consistency in cement-based building materials.

Product Description

• Product Name: Hydroxyethyl methyl cellulose / HEMC

• Other Name: Methylhydroxyethylcellulose, Cellulose 2-hydroxyethyl methyl ether, HEMC

• Appearance: White powder

• CAS: 9032-42-2

•              Usage: Water-based paints and coatings, building materials, liquid detergent

Hydroxyethyl methyl cellulose (HEMC/MHEC) is widely used in water-based latex coatings, building materials, printing ink, oil drilling, and other industries. It provides excellent thickening effects and water-retaining properties, and greatly improves workability.

  Applications

             Food Processing

• Can be used as a bonding agent, emulsifier, film former, thickener, suspension agent, dispersant, and water retention agent

             Daily Chemical Industry

• Used as an additive for toothpaste, cosmetics, detergents, and other products

             Building Materials

• Works as a gelling agent and water retention agent for cement, gypsum, and lime

• An excellent admixture for powder building materials

             Pharmaceutical Preparations

• Hydroxyethyl methyl cellulose is widely used as an excipient in oral tablets, suspensions, and topical preparations

• Similar to methyl cellulose, but the presence of hydroxyethyl makes it more water-soluble, more compatible with salts, and gives it a higher gelation temperature

  Key Benefits for Concrete Admixture

• Water Retention – Keeps water in the mix so cement hydrates fully

• Improved Workability – Makes concrete easier to mix, place, and finish

• Consistency Control – Maintains uniform properties throughout the batch

• Better Adhesion – Improves bond strength to substrates

• Sag Resistance – Prevents slump and flow issues on vertical surfaces
