HEMC & MHEC

Kemox HEMC is a different kind of cellulose ether from HPMC. The substitute groups of HEMC are hydroxypropyl and methoxy,Compared with HPMC, HEMC has more hydrophilic groups, which means it has a relatively high gel temperature, better water retention in hot environments, and better thermal sta-bility.

Kemox hydroxyethyl methyl cellulose(HEMC or MHEC) provides many of the same benefits as other methylcellulose derivatives, such as the ability to efficiently thicken and provide water retention, are highly effective additives used to improve the quality and processing characteristics of building materials such as plasters and renders, mortars, tile adhesives, joint compounds and emulsion paints.

HEMC Asked Questions

When choosing HEMC viscosity, consider the specific requirements of your application, such as desired consistency, water retention, and overall performance. Consult the Kemox&#;s guidelines to make an informed decision.

HEMC grades are differentiated based on their viscosity, which is typically measured in mPa·s (millipascal-seconds) or cP (centipoise). Different grades offer varying performance characteristics, such as water retention, solubility, and thickening ability.

When selecting HEMC, consider the specific application area and performance requirements, including viscosity, solubility, and water retention properties.

Yes, HEMC can be combined with other cellulose ethers, such as HPMC or HEC, to achieve desired properties in a specific application. The compatibility and performance of combined products should be tested before use to ensure optimal results.

Yes, HEMC is compatible with various types of cement, including Portland cement, slag cement, and fly ash cement. Its benefits and performance may vary slightly depending on the cement type and formulation.

HEMC is biodegradable and has minimal environmental impact during its use and disposal, making it an eco-friendly material.

Hydroxyethyl Methyl Cellulose (HEMC) is also named as Methyl Hydroxyethyl Cellulose (MHEC). It is a white, grayish-white, or yellowish-white granules.

It is a non-ionic cellulose ether derived from the addition of ethylene oxide to methylcellulose. It is produced from a natural renewable polymer such as wood pulp or cotton.

HEMC can be used as a highly efficient water retention agent, adhesives and film-forming agent, stabilizer, etc.

It is widely used in different industrial applications such as oil drilling, construction, and building, paint and coating, pharmaceutical, etc.

Cement plaster:

Improve homogeneity, make the mortar more easily coated, and improve the anti-sagging ability. Enhance liquidity and pumpability, thus improving working efficiency.

High water retention, prolong the working time of mortar, improve work efficiency, and facilitate the formation of high mechanical strength during solidification period.

Control the infiltration of air, thus eliminating the microcracks of the coating and forming the ideal smooth surface.

Gypsum plaster:

Improve homogeneity, make the mortar more easily coated, and improve the anti-sagging ability to enhance the mobility and pumpability. Thus, the work efficiency is improved.

High water retention, longer working time of mortar, and high mechanical strength during solidification.

A high quality surface coating is formed by controlling the consistency of the mortar.

Masonry mortar:

Strengthen the adhesion of the surface of the masonry, and enhance the water retention, so as to improve the strength of mortar.

Improve the lubrication and plasticity so as to improve the construction performance, and use the mortar made of &#;guaranteed&#; cellulose ether to make it easier to apply and save time, and improve the cost-effectiveness.

The model with special high water retention can be used for high absorbent bricks.

It is used to fill the material:

Excellent water retention, can prolong cooling time and improve working efficiency. High lubricity, make use easier, smooth.

Improve the anti-contractility and crack resistance and improve the surface quality.

Provide smooth and uniform texture, and make the joint surface more cohesive.

Tile adhesive:

Make the dry mixing ingredients easy to mix, and will not produce a mass, thus saving working time. As the application is faster and more effective, it can improve the construction and reduce the cost.

Improve the efficiency of tiling by lengthening the cooling time. Provides excellent adhesion effect.

Special development model with high anti-skid resistance can be provided.

Self-leveling the ground material:

Provide viscosity, which can be used as an anti &#; precipitation agent.

Enhance the liquidity and pumpability, thus improving the efficiency of the flooring.

Control water retention, thus greatly reducing cracking and shrinkage.

Water based paint and paint remover:

The shelf life is extended by preventing solid precipitation. Excellent compatibility with other components and high biostability.

Dissolve fast and without mass, which helps to simplify the mixing process. The cold water disperses the model product, can make the mix more quick and convenient, and does not produce the mass.

Generate favorable flow characteristics, including low spatter and good leveling, to ensure fine surface finish and prevent the flow of paint.

Enhance the viscosity of the water-based paint remover and organic solvent, so that the paint remover will not flow out of the surface of the workpiece.

Extruded concrete plank:

Enhance the processing performance of extruded products, with high bonding strength and lubrication.

Improve the adhesiveness of wet strength and sheet extrusion.
