Gerneral Overview
Special putty grade sodium carboxymethyl cellulose cmc powder is a cost-effective modifier tailored for wall putty systems. Our cmc powder provides smooth construction performance and good water retention.
Core Product Advantages
1. Smooth & Delicate Construction: Smooth scraping without knife sticking, delivers flat and delicate putty surface with few joint marks and easy burnishing.
2. Drying Shrinkage Crack Prevention: Maintains uniform drying of putty layer, reduces plastic cracking and powdering problems.
3. Good Leveling Performance: Endows putty with moderate leveling ability, automatically fills minor base defects and improves leveling efficiency.
4. Outstanding Cost Advantage: Significant cost advantage over HPMC, making it an ideal choice for economical putty formulas.
Product Specifications
Construction Grade Sodium Carboxymethyl Cellulose (5000 mPa·s, DS:0.72) is a medium-viscosity multifunctional anionic cellulose ether and universal cost-effective building modifier. It balances moderate thickening, reliable water retention and good fluidity, improving mortar workability and extending construction time. It resists drying shrinkage cracking, features stable performance and wide compatibility for most conventional dry-mix mortar systems.
