Gerneral Overview
High viscosity cmc 16000 mPa·s sodium carboxymethyl cellulose is a special thickening additive for thick-layer building material construction. Our cmc powder delivers ultra-high thickening efficiency and anti-sagging ability.
Core Product Advantages
1. Ultra-high Thickening Efficiency: High-viscosity grade delivers strong thickening capacity at low dosage, optimizes formula cost.
2. Excellent Sag Resistance: Effectively supports mortar structure during thick-layer construction, no sagging or falling off on vertical surfaces.
3. Long-lasting Water Retention: Maintains moisture in mortar for a long time, ensures uniform drying inside and outside thick layers and reduces delamination and cracking.
4. Stable Mortar System: Prevents aggregate settlement and delamination, ensures uniform composition and consistent performance.
Product Specifications
Construction Grade Sodium Carboxymethyl Cellulose (16000 mPa·s, DS:0.76) is a high-viscosity thickening anionic cellulose ether for thick-layer building material construction. It delivers ultra-high thickening efficiency and excellent anti-sagging ability to stabilize mortar structure and prevent sagging and cracking. With durable water retention and stable pH adaptability, it matches well with cement and gypsum systems for thick putty and insulation mortar applications.
