Optimizing Skim Coat Formulations with Cellulose Ether Additives

In dry-mix mortar production, choosing the right cellulose ether determines the final product's open time and sag resistance. Celix PM-55U is engineered to eliminate the most common application failures in skim coat and wall putty powder

Addressing Cracking & Dehydration

Our cellulose ether polymer (HPMC) provides exceptional water retention (up to 95%), holding hydration water within the thin cement/gypsum matrix, preventing premature drying on highly absorbent substrates.

Eliminating Blistering & Sagging:

With a precise 55,000 mPa.s Brookfield viscosity profile, PM-55U introduces optimal pseudoplasticity (shear-thinning behavior). It applies effortlessly under the trowel but stands firm once applied, preventing sagging.

Enhancing Lumps-Free Dissolution:

Specially treated particles ensure uniform dispersion in dry-mix plants, preventing dry lumps and local air entrainment during mixing.


Industrial Specifications & Application Guidelines

Our hpmc products utilize advanced, fully automated reactor technology from Germany, ensuring high product purity, cost-effectiveness, and consistent quality. This technological advantage allows us to offer affordable solutions without compromising performance reliability.

Frequently Asked Questions (FAQ)

What is the main role of cellulose ether in skim coat applications?

In skim coat and wall putty, cellulose ether (primarily HPMC or MHEC) serves three vital functions: it provides high water retention to allow proper cement hydration, significantly improves workability for smoother troweling, and enhances sag resistance to ensure a uniform layer thickness on vertical walls.

Can Celix customize the viscosity and open time of HPMC?

Yes. Through our Customized Formulation Service, our R&D team can adjust the etherification degrees, viscosity ranges (from 40,000 to 200,000 mPa.s), and surface treatments to match your specific local temperature, humidity, and raw material variations.

How does Celix ensure batch consistency for large volume exports?

We utilize fully automated DCS manufacturing systems that tightly control raw material feeding, reaction temperatures, and pressure profiles. Furthermore, pre-shipment samples from our laboratories are archived for 2 years to ensure full traceability for every container shipped.
