HPMC

Hydroxypropyl Methyl cellulose

JTBON® Hydroxypropyl Methyl Cellulose(HPMC) is a high-performance, non-ionic cellulose ether derived from refined cotton through etherification with propylene oxide and methyl chloride. It appears as a white or off-white powder that dissolves readily in cold water, forming a transparent or slightly turbid viscous solution. This product is compatible with all conventional mineral binders used in cement-based systems, making it an ideal additive for enhancing the performance of various construction materials.

Key Advantages

Excellent Water Retention

Enhances water retention in cementitious materials, ensuring proper hydration and reducing the risk of premature drying and shrinkage.
Improved Workability and Consistency

Acts as a thickener and rheology modifier, providing a uniform and cohesive texture to mortars and plasters, which facilitates easier application and better handling.
Enhanced Adhesion

Improves the bond strength between construction materials and substrates, such as bricks, blocks, or stones, leading to more durable and long-lasting structures.
Extended Open Time

Prolongs the working time of mortars and adhesives, allowing for adjustments and repositioning during application without compromising performance.
Sag Resistance

Increases the viscosity of mixtures, reducing sagging and slumping in vertical or overhead applications, ensuring materials stay in place during setting.
Compatibility with Other Additives

Can be easily combined with various admixtures, such as air-entraining agents or plasticizers, without negatively affecting performance, allowing for customized formulations tailored to specific project requirements.

Q&A

Q1: What are the primary application areas of HPMC in the construction industry?

A: HPMC is widely used in cement mortars, tile adhesives, plasters, renders, self-leveling compounds, and gypsum-based materials to enhance workability, water retention, and adhesion.
Q2: How to choose the appropriate HPMC variety?

A: Selection depends on the specific application and desired properties. For instance, higher viscosity HPMC is suitable for tile adhesives requiring sag resistance, while lower viscosity types are preferred for self-leveling compounds needing smooth flow.
Q3: What are the usage methods and precautions for HPMC?

A: To avoid clumping, HPMC should be dispersed in hot water with continuous stirring, then cooled to achieve full dissolution. Ensure proper mixing to maintain consistency.
Q4: Can HPMC be mixed with other additives in construction materials?

A: Yes, HPMC is compatible with various additives like plasticizers, defoamers, and retarders, enhancing the performance of construction materials.
Q5: What are the storage conditions for HPMC?

A: Store HPMC in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources. The recommended storage temperature is between 10°C and 30°C.
Q6: What are the precautions for HPMC transportation?

A: Ensure packaging is intact to prevent moisture ingress. Avoid exposure to heat and do not transport with toxic or hazardous substances.
