Hydroxyethyl Methyl Cellulose (HEMC/MHEC)

BOTAI HEMC/MHEC is synthesized by etherifying alkali cellulose with ethylene oxide and methyl chloride. Known for ultra-high water retention, rapid dissolution, and minimal air entrainment, it optimizes performance in high-end construction applications (e.g., self-leveling compounds, gypsum plasters) and water-based coatings. Its low-bubble formula improves final strength and surface finish.

Product Model Introduction

Bomcell® MEC112(S)

MEC112(S) is designed for cement-based applications.It imparts well-balanced properties, including open time, adhesion properties and shear strength. It is compatible with all conventional minerals and organic binders.

Bomcell® MEC165(S)

MEC165(S) is used in cement based render, EIFS, tile adhesive and joint mortars for improvement of the workability properties. It was specially developed to achieve good sag resistance in such systems.

Bomcell® MEC108(S)

MEC108(S) is compatible with all conventional minerals and organic binders.It imparts well-balanced properties, including adhesion properties and shear strength.

Bomcell® MEC323(S)

MEC323(S) has been developed to improve the high anti-sagging and strength properties. It provides good water retention and good workability properties of cement or gypsum based dry mixing mortars.

Bomcell® MEC956(S)

MEC956(S) has been developed to improve the excellent workability properties of Portland cement based dry mixing mortars. It provides high water retention properties while still offering good anti-sagging properties.

Bomcell® MEC988(S)

MEC988(S) exhibits very high water retention and thus reduces the absorption of water into porous substrates. The high efficiency enables formulation of tile cement at low additive costs by reducing the cellulose ether dosage. The adjustability time is good even at low MEC988(S) dosages and high ambient temperatures.

Application Scope

Insulation mortar system

Cement-based plaster mortar

Putty

Tile adhesive

Self-leveling mortar

Water-based paint

1. Excellent moisturizing properties: HEMC has excellent moisturizing properties and can retain moisture in various mixtures, ensuring that materials such as cement, putty, primer, etc. have sufficient time for hydration, thereby enhancing the strength and durability of the materials.

2. Enhanced bonding strength: In tile adhesives and putties, HEMC can significantly improve bonding strength, ensuring that tiles and putties adhere firmly to the substrate and reducing the risk of falling off and cracking.

3. Prevent cracking and shrinkage: In external wall insulation systems and putties, the addition of HEMC can reduce shrinkage and reduce the chance of cracks and other defects, thereby maintaining the integrity and beauty of the surface.

4. Improved self-leveling performance: In self-leveling compounds, HEMC acts as a thickener, allowing the compound to be easily and evenly distributed on the surface to form a smooth and uniform film. This helps improve the flatness and aesthetics of the floor.

5.Improved construction performance: In paints and coatings, HEMC helps adjust viscosity and improve flow characteristics for smoother construction. At the same time, it can stabilize the suspension of pigments and other particles, prevent sedimentation, and maintain the consistency and uniformity of the coating.

6. Easy to combine with other materials:
HEMC has good compatibility and can be easily combined with other additives and materials used in various formulations to achieve a variety of customized properties to meet the needs of different applications.
