Methyl Hydroxyethyl Cellulose (MHEC)

CELOPRO® MH is the high-performance additive that upgrades the stability and quality of your:

  • Plasters and Renders
  • Mortars and Grouts
  • Tile Adhesives
  • Skim Coat and Wall Putties
  • Joint Compounds
  • Emulsion Paints (Water-based)

When the final appearance and application stability of your building materials depend on precise performance, Methyl Hydroxyethyl Cellulose (MHEC) is the essential additive. Celotech’s CELOPRO® MH series is engineered as a highly effective, cost-optimized alternative that significantly enhances the processing characteristics and long-term quality of your formulations.

Functions of MHEC

  • Enhanced Workability & Finish: Provides superior thickening and lubricity, ensuring an effortless, smooth application with reduced drag. This is crucial for achieving high-quality finishes in plasters and renders.

  • Reliable Water Retention: Efficiently controls water movement throughout the setting process, preventing premature drying. This guarantees longer open times and effectively minimizes cracking in the cured material.

  • Superior Anti-Sag/Anti-Slip: Optimizes the yield strength of wet mortars, minimizing slump and maximizing anti-slip properties—a critical factor for tile adhesives and thicker skim coats.

  • Consistent Quality Assurance: CELOPRO® MH is designed for reliable batch-to-batch performance, ensuring predictable processing characteristics and a consistently high-quality final product.

Frequently Asked Questions

MHEC is widely used in the field of construction, mainly in dry-mix mortar, tile adhesive, waterproof coating,building materials,etc. It can increase the adhesion of mortar, making it denser and improving its crack resistance and impermeability. For paint & coating, MHEC can significantly improve the adhesion, stability , water resistance and durability of coatings.

The difference between the HPMC and MHEC is reflected in the gel temperature.The gel temperatures of the two are different. The gel temperature is a critical point for the application of cellulose ether. When the ambient temperature exceeds the gel temperature, cellulose ether will separate from water and lose its water retention property.This means that cellulose ether will become invalid and lose its viscosity.
