High viscosity 200000 HPMC cellulose ether powder

High-viscosity Hydroxypropyl Methyl Cellulose (HPMC) with a viscosity rating of 200,000 cps (centipoise) is a specific grade of cellulose ether known for its thickening and gelling properties. This high viscosity makes it suitable for applications requiring substantial water retention, improved workability, and enhanced adhesion.

Characteristics of High Viscosity 200,000 cps HPMC

1. Thickening Agent:

   • The high viscosity of 200,000 cps HPMC provides strong thickening effects, making it ideal for creating dense and stable mixtures in various applications.

2. Water Retention:

   • It exhibits excellent water retention properties, which are critical for controlling the evaporation of water in construction materials. This ensures better hydration of cement and gypsum, leading to improved strength and durability.

3. Consistency and Stability:

   • High-viscosity HPMC provides a smooth and homogeneous consistency to mixtures, ensuring uniform application and preventing segregation of components.

4. Thermal Gelation:

   • Like other HPMC grades, this high-viscosity type exhibits thermal gelation, where it forms a gel upon heating and reverts to a liquid state upon cooling. This property can be useful in controlling the setting and drying times of mixtures.

5. Film-Forming Ability:

   • HPMC can form a thin, flexible film upon drying, which can enhance surface properties like smoothness and adhesion.

Applications of High Viscosity 200,000 cps HPMC in Construction

1. Tile Adhesives:

   • High-viscosity HPMC cellulose is used to improve the open time, workability, and adhesion strength of tile adhesives. It helps prevent tiles from slipping and ensures a strong bond with the substrate.

2. Plasters and Renders:

   • In cement and gypsum-based plasters, high-viscosity HPMC enhances workability and water retention, preventing premature drying and cracking. It also helps in achieving a smooth surface finish.

3. Self-Leveling Compounds:

   • It is used in self-leveling compounds to control the flow properties, ensuring a smooth, level surface without segregation.

4. Masonry Mortars:

   • High-viscosity HPMC improves the cohesiveness and water retention of masonry mortars, enhancing their strength and workability.

5. External Thermal Insulation Systems (ETICS):

   • It is used in adhesive and base coat formulations for ETICS, providing strong adhesion and improved workability.

Handling and Usage

• Dissolution: High-viscosity HPMC should be properly dissolved in water or a suitable solvent. It is usually added slowly to the liquid while stirring to avoid clumping. Warm water can facilitate the dissolution process.
• Concentration: The concentration of HPMC in the mix should be carefully controlled to achieve the desired viscosity and performance characteristics.

Benefits of Using High Viscosity 200,000 cps HPMC

1. Enhanced Performance:

   • The high viscosity of this grade provides superior performance in terms of thickening, water retention, and stability, making it ideal for demanding applications.

2. Versatility:

   • It can be used across a wide range of construction applications, from tile adhesives to plasters and mortars, offering consistent quality and performance.

3. Durability:

   • By improving the workability and adhesion of construction materials, high-viscosity HPMC contributes to the long-term durability and stability of the final product.

High-viscosity 200,000 cps HPMC cellulose ether powder is a valuable additive in the construction industry, offering exceptional thickening, water retention, and adhesion properties. Its versatility and effectiveness make it an essential component in various construction materials, ensuring high-quality and durable end products.
