HEMC 400

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

Overview of HEMC 400

HEMC 400 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 400

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 400

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.
