Diatom mud is an eco-friendly interior wall finishing material made from natural diatomaceous earth, known for its strong adsorption capacity, breathability, and decorative appeal. It is widely used in modern green buildings for creating healthy and stylish living environments.
For diatom mud manufacturers, balancing eco-friendly properies with exceptional workabilitly and zero-defect durability is a constantchalenge. Celix pure-grade HPMC and HEMC/MHEC are engineered to seamlessly align with your industrial formulations, solvingcritical application pain points from the laboratory to the construction site.
Extended Open Time & Superior Anti-Sagging Properties
Our modihed Celix Pro series provides highly controlled thickening and shear-thinning behavior. it signifcantly extends the opertime of diatom mud even in hot or dry cimates, allowing applicators ample time to create intricate artistic textures such as brick.wave, or combed patterns) without premature skinning or formulation crusting.
90%+ High Water Retention: Eliminate Cracking & Powdering
Celix industrial HPMC offers a superior water retention rate (90%+ under high-temperature testing). By locking water withinthe matrix., it ensures balanced, uniform drving and fawless hydration of cementiious or gypsum binders, completely eliminatingcommon consumer complaints about cracking and surface shedding.
Optimized Slip & Workability for Effortless Application
Celix cellulose ethers impart an optimal pseudoplastic viscosity prole to the wet mix, This delivers a smooth, butery consistenclwith excellent lubrication. lt reduces dynamic friction during troweling, dramaically improving applicaion speed and reducingohysical fatigue for the plasterers on-site.
Enhanced Adhesion & Matrix Consistency
Operating in synergy with VAE RDP, Celix HPMC ensures legal-limit wet mortar stability, preventing phase separation or bleeding.It locks the internal formulation structure together, providing higher tensile adhesion strength and impact resistance after ful curing.
Diatom mud typically contains cellulose ethers like Hydroxypropyl Methyl Cellulose (HPMC) or Methyl Hydroxyethyl Cellulose (HEMC/MHEC). These additives are added to improve water retention, enhance workability and plasticity, provide better adhesion to substrates, and thicken the mixture, helping to prevent cracking and improve overall performance.

Whether you're looking for slip resistance, good adhesion to different substrates, or resistance to a wide range of climatic conditions, Celix's Pure grade Cellulose Ethers and Modified grade 'Celix Pro' product range impart properties in cement-based mortar formulations that help meet modern building industry standards.
When you choose Celix, you are not just buying additives
you are partnering directly with a fully integrateo ISO-certifed cellulose ether manufacturer. We eliminate the middlemen to deliver stable chemistry, certifeoquality, and reliable supply chains to over 150 countries.

Direct From Our 30,000-Ton Capacity Factory
Celix operates modern, automated production lines with an annual capacity of 30.000 metric tonsFor our partners, this means a daily production stability of up to 80 tons, quaranteeing that youroeak-season orders are always manufactured and dispatched on time, with zero intermediate markups.

24/7 Quality Control & The Celix Application Lab
Our state-of-the-art laboratory monitors every production phase-from raw cotton lint selection tofinal etherification. Led by our chief application specialist, Engineer, we perform real-time viscosity.ash content, and water-retention testing to ensure that the material you receive tomorrow performsexactly like the sample you approved today.

Free Sample Program for Industrial Verification
We understand that switching chemical suppliers requires rigorous verification. Celix offers freesample kits (200g - 600g) tailored to your required viscosity grade. Every sample is drawn fromactive production batches and comes with a complete Certificate of Analysis (COA) for your R&Dteam's evaluation.

Tailored Packaging & Flexible Logistics
Engineered for Safe Transit: To protect the high-purity cellulose from moisture duringlong ocean transits, we use multi-layer paper-plastic composite bags with vapor barriers(Standard: 25kg/bag). We also support customized private-label packaging (OEM) andHexible palletization options to match your local warehousing and handling requirements.

Q: What is the recommended dosage of HPMC in diatom mud formulations?
A: Generally, the dosage ranges from 0.2% to 0.4%, depending on the specific texture requirementsand substrate conditions. Contact our engineers for a tailored formula optimization.
Q: Why does diatom mud crack, and how does Celix cellulose ether prevent it?
A: Cracking is usually caused by rapid water loss. Celix pure-grade HPMC offers superior waterretention (90%+at high temperatures), ensuring balanced drying and maximum surface strength
