Landercoll HPMC for wall putty & skim coat
China HPMC Manufacturer
Landercoll HPMC (Hydroxypropyl Methyl Cellulose) is produced via etherification of refined cellulose with methyl and hydroxypropyl groups. When mixed with water, it rapidly dissolves to form a clear, viscous colloidal solution, significantly improving water retention, smooth trowelability, and crack resistance in wall putty and skim coat formulations.
As a professional cellulose ether manufacturer, Landercoll offers both standard and customized HPMC grades tailored for interior and exterior wall putties, ensuring consistent quality and on‑time supply.
- Excellent water retention for consistent workability
- ISO-certified production, REACH-compliant for European markets.
- Moisture content: ≤5% | Ash content:≤3% | pH value: 6-8

HPMC 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.
HPMC 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.
