HEMC finds extensive applications in various industries, including water-based latex coatings, building construction and materials, printing inks, and oil drilling. In the context of building construction, its primary uses encompass cement-based plasters, gypsum plasters, masonry mortars, joint sealing for slabs, adhesives for tiles, and concrete slab formulations. It's a custom cas 9032 42 2 HEMC cellulose product, feel free to contact us.

Main Purpose of Hydroxyethyl Methyl Cellulose HEMC

Cement-based plastering mortar: It has good thixotropy and ease of bonding, making the mortar pumpable. At the same time, it improves the anti-sagging ability and high water retention, and prolongs the working time of the mortar, which helps the mortar to form a high mechanical strength during the setting period.

Gypsum plasters and gypsum products: act as binders, are thixotropic and retarded to improve spreadability and work time. It has water retention, so that the slurry will not crack due to drying too fast after application, and enhances the strength after hardening.

Masonry mortar: enhance the adhesion with the surface of the masonry, and can enhance the water retention, so that the strength of the mortar can be improved.

Board joint filler: It has excellent water retention, lubricity, high shrinkage resistance and crack resistance, provides a smooth and uniform texture for the material, and makes the bonding surface stronger.

Ceramic manufacturing: It is widely used as a binder in the manufacture of ceramic products.

Self-leveling flooring materials: Enhance fluidity and pumpability for more efficient flooring and control water retention to greatly reduce cracking and shrinkage.

Extruded concrete slabs: Enhance the processability of extruded products, with high bond strength and lubricity. Improves wet strength and adhesion after sheet extrusion.
