HEMC 150H

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

Overview of HEMC 150H

HEMC 150H 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.
