LANDERCOLL MHEC for EIFS/ETICS Systems

Home > Applications > MHEC for Wall Putty
China MHEC Manufacturer

Trusted Water Retention & Anti-Sag Cellulose Ether

Landercoll MHEC (Methyl Hydroxyethyl Cellulose) is produced via etherification of refined cellulose with methyl and hydroxyethyl groups. When dispersed in EIFS/ETICS mortar systems, it rapidly hydrates to form a stable colloidal solution, delivering exceptional water retention, extended open time, and superior anti‑sag properties – ensuring consistent trowelability and strong bond strength on vertical substrates.

As a dedicated cellulose ether supplier, Landercoll offers both standard and customized MHEC grades engineered specifically for exterior insulation and finish systems, backed by rigorous quality control and technical support.

MHEC Supplier with Good Reputation

Landercoll® has been a trusted name in cellulose ether manufacturing for years, backed by three production bases equipped with state-of-the-art facilities. Our manufacturing process features 16 horizontal reactors and 4 vertical reactors ensuring high-capacity, consistent output, alongside a DCS (Distributed Control System) for fully automated production and an SIS (Safety Instrumented System) for real-time process safety.

MHEC Manufacturing & Purification Process

Raw Material Selection: We begin with high-purity refined cotton linter, characterized by low ash and negligible impurities.

Etherification: The cellulose is alkalized under precisely controlled conditions, followed by etherification to introduce methoxyl and hydroxypropyl groups.

Purification: The crude product undergoes successive washing and filtration stages to remove by‑products and residual salts, achieving exceptional purity suitable for demanding applications.
