HEMC 200H

Very-high-viscosity HEMC for high water retention, body, and anti-sag construction performance.

Overview of HEMC 200H

HEMC 200H is a methyl hydroxyethyl cellulose grade designed for construction systems that need high viscosity, strong water retention, and improved application body. It supports longer open time, better anti-sag behavior, and more stable wet mortar performance in demanding dry-mix formulations.

Benefits of HEMC 200H

  • High viscosity build for demanding dry-mix systems
  • Strong water retention and application body
  • Supports longer open time and anti-sag behavior
  • Improves wet mortar consistency and workability
  • Useful in tile adhesive, EIFS mortar, putty, and plaster
  • Practical for high-performance construction screening

Typical Applications of HEMC 200H

1.Tile adhesive and large-format tile systems
Suitable for formulas that need stronger water retention, open time, and anti-sag support.

2.Wall putty, skim coat, and plaster
Useful where higher body, better workability, and stable vertical application are required.

3.EIFS mortar and repair mortar
Appropriate for systems that need consistent wet mortar structure and application stability.
