Water Resistance: Yes. This confirms the coating's ability to form an effective barrier against moisture penetration and erosion, particularly crucial for paper, textiles, construction materials, and food packaging applications where product longevity and performance maintenance are essential.
EINECS No.: 232-734-4. This unique European chemical inventory identifier confirms product registration within the European Economic Area, ensuring compliance with chemical management regulations for international trade.
Classification: Chemical Auxiliary Agent. This designation indicates CMC's primary role as a supplementary material that enhances final product performance or processing characteristics when combined with other substances.
Purity: 98% minimum. The high purity guarantees product quality by minimizing insoluble matter and impurities, ensuring stability and reliability across applications.
Coverage: 10-12 m²/L. This parameter provides economic reference for practical applications, enabling users to estimate costs and material requirements.
Grade: High Viscosity. This specification indicates high molecular weight and/or substitution degree, suitable for applications requiring viscous solutions such as thickening, stabilization, or forming substantial protective layers.
Adhesion: Excellent. Superior adhesion ensures firm bonding to various substrates without peeling, guaranteeing coating durability and protective effectiveness.
Color: White. The pure white appearance makes it ideal for aesthetically sensitive applications without altering substrate colors or introducing unwanted hues.
EC No.: E466. This European food additive designation confirms its use as a food additive (e.g., thickener, stabilizer), implying safety and compliance in other applications.
Degree of Substitution (D.S.): 0.8-0.9. This precise range balances CMC's hydrophilic and hydrophobic properties, influencing solubility, solution viscosity, film flexibility, and material compatibility.

III. Core Application Fields

The high-viscosity CMC coating product demonstrates versatile applications across multiple industries:

Construction: Used in mortar, putty, and tile adhesives as thickener and water-retention agent, improving workability while enhancing bond strength and durability. Excellent adhesion and water resistance also provide effective protection for exterior coatings and waterproof layers.
Automotive: Applied in rust-proofing, body sealing, and interior component bonding/surface treatment, with superior adhesion and weather resistance contributing to vehicle quality and lifespan.
Packaging: Enhances paper/board oil, water, and tear resistance while improving printability. In food packaging, its E466 safety classification makes it ideal for internal coatings that separate food from packaging materials to extend shelf life.
Textiles: Functions as thickener in printing paste formulations for clear patterns and vibrant colors, while improving fabric softness, wrinkle resistance, and drape as finishing agent.
Paper: Sizes and surface-coats paper to enhance strength, smoothness, printability, and water resistance for higher-quality products.
Food: As additive E466, widely used as thickener, stabilizer, emulsifier, and suspending agent in ice cream, beverages, sauces, and baked goods to improve texture, mouthfeel, and stability.
Pharmaceuticals: Functions as binder, disintegrant, and sustained-release material in tablets to control drug release rates, while thickening and stabilizing oral liquids and suspensions.
Other Industrial Applications: Including ceramic glazes, inks, drilling fluids, cosmetics, and detergents, where it serves thickening, stabilizing, water-retaining, and bonding roles.
