It is a high quality modified cellulose ether product developed for cement-based tile adhesive and plaster mortar applications, which can significantly improve the construction performance of tile adhesive.
| Property | Description |
|---|---|
| Chemical Structure | Modified cellulose ether is derived from natural cellulose through etherification and cross-linking reactions. |
| Appearance | White to off-white powder, free-flowing. |
| Solubility | Soluble in water to form viscous solutions, with modified versions offering enhanced solubility characteristics. |
| Property | Original Cellulose Ether | Modified Cellulose Ether |
|---|---|---|
| Water Retention | Good | Significantly improved, up to 17% higher with certain modifications |
| Mechanical Strength | Moderate | Increased, with flexural strength and compressive strength improved by 14.05% and 7.12% respectively |
| Viscosity | High | Further increased, leading to improved thickening properties |
| Application Area | Usage |
|---|---|
| Building Materials | Used in mortars to enhance cohesiveness, water retention, and workability. |
| Adhesives | Provides improved bonding strength and stability in adhesive formulations. |
| Coatings | Enhances the rheological properties and film-forming capabilities. |
Modified cellulose ether (STD4019P type) is a versatile material with enhanced properties compared to traditional cellulose ethers. Its improved water retention, mechanical strength, and viscosity make it suitable for a wide range of applications, particularly in construction materials and adhesives.
