Hydroxyethyl Methylcellulose for Mortar

Hydroxyethyl methyl cellulose (HEMC) is one of the most popular cellulose ethers. They are a group of admixtures, with the use of which it is possible to modify the viscosity of pastes and mortars, and, thus, change their rheological or application properties.

Specification

HEMC Main application

Hydroxyethyl methyl cellulose (HEMC) is a non-ionic cellulose mixed ether made from cotton and wood through alkalization, ethylene oxide and methyl chloride etherification. HEMC is widely used in water-based latex coatings, construction and building materials, printing ink, oil drilling and other fields. Its properties are similar to HPMC, but the presence of hydroxyethyl makes HEMC more soluble in water, the solution is more compatible with salt, and has a higher condensation temperature.

In the field of building materials, it is used as a gelling agent and water retaining agent for cement, gypsum and lime, and is an excellent admixture for powder building materials.

HEMC packaging and storage

Barrel or paper plastic bag lined with polyethylene film inner bag. Net weight of each bag: 25kg.
