HEMC LH40M for C2 Tile Adhesive Long Open Time

short description:

Hydroxyethylmethylcellulose (HEMC) is a water-soluble polymer commonly used as a thickener, gelling agent, and adhesive. It is obtained by chemical reaction of methyl cellulose and vinyl chloride alcohol. HEMC has good solubility and flowability, and is widely used in fields such as water-based coatings, building materials, textiles, personal care products, and food.

In water-based coatings, HEMC can play a role in thickening and viscosity control, improving the flowability and coating performance of the coating, making it easy to apply and apply. In building materials, HEMC is commonly used in products such as dry mixed mortar, cement mortar, ceramic tile adhesive, etc. It can increase its adhesion, improve flowability, and improve the water resistance and durability of the material.
