HEMC 30K

Medium-to-high viscosity HEMC for dry-mix construction materials and controlled workability.

Overview of HEMC 30K

HEMC 30K is a methyl hydroxyethyl cellulose grade designed for dry-mix construction systems that need balanced water retention, workability, and controlled consistency. It is suitable for tile adhesive, wall putty, skim coat, plaster, and mortar formulas that require stable handling on site.

Benefits of HEMC 30K

Balanced viscosity build for dry-mix systems
Improves water retention and workable consistency
Supports open time and smoother application
Helps reduce sagging in suitable vertical formulas
Useful in tile adhesive, putty, plaster, and mortar
Practical for construction grade screening

Typical Applications of HEMC 30K

1.Tile adhesive
Suitable for improving water retention, open time, troweling feel, and wet mortar consistency.

2.Wall putty and skim coat
Useful where the formula needs smooth scraping, stable paste body, and better finishing behavior.

3.Cement plaster, gypsum plaster, and mortar
Appropriate where workability, water retention, and site handling stability are required.
