HEMC 4K

Low-to-mid viscosity HEMC for lower-body construction and water-based systems.

Overview of HEMC 4K

HEMC 4K is a methyl hydroxyethyl cellulose grade designed for formulas that need lower viscosity, controlled flow, and basic water-retention support. It is useful for construction and water-based systems where easy mixing, smooth spreading, and lighter consistency are required.

Benefits of HEMC 4K

  • Lower viscosity build with good processability
  • Supports basic water retention in light systems
  • Helps improve smooth mixing and spreading
  • Useful for flowable or lower-body construction formulas
  • Compatible with cement-based and gypsum-based systems
  • Practical for initial formulation screening

Typical Applications of HEMC 4K

1.Self-leveling and flowable mortar systems
Suitable where the formula needs water retention support while keeping easier flow.

2.Light skim coat and finishing formulas
Useful where smooth spreading and controlled low-to-mid body are required.

3.Coatings and selected daily-chemical systems
Appropriate for testing in water-based systems that need moderate thickening and handling support.
