Product Summary

Hydroxypropyl Methyl Cellulose (HPMC), identified by CAS number 9004-65-3, is a high-purity cellulose ether widely utilized in building chemicals. It is originated from all-natural cellulose and customized via chemical handling to deliver consistent performance in industrial applications.

Secret Physical Qualities

This HPMC looks like a white to off-white free-flowing powder. It has no obvious odor and dissolves quickly in cold water to create clear, thick remedies. The product does not dissolve in warm water, alcohols, or most natural solvents. Common thickness ranges from 4,000 to 100,000 mPa · s (determined at 2% concentration, 20 ° C), depending on the grade chosen.

Chemical Composition

HPMC consists of methoxy groups (– OCH FIVE) and hydroxypropyl groups (– OCH TWO CHOHCH ₃) connected to the cellulose backbone. The methoxy material generally drops in between 19% and 30%, while hydroxypropoxy material ranges from 4% to 32%. These replacements identify solubility, gel temperature, and thickening efficiency.

Performance in Construction Applications

In cement-based products like floor tile adhesives, provides, and self-leveling compounds, HPMC acts as a water retention agent, thickener, and workability enhancer. It reduces water loss during healing, which helps enhance adhesion and minimizes breaking. The polymer likewise supplies superb open time and sag resistance, especially on vertical surfaces.

Storage and Handling

Shop HPMC in an amazing, completely dry location far from wetness and direct sunshine. Keep containers firmly secured when not in use. The life span is commonly one year under proper storage problems. Stay clear of breathing of dirt throughout handling; utilize conventional personal safety devices such as handwear covers and shatterproof glass.

Packaging

The item is crammed in multi-layer paper bags with internal polyethylene liners. Typical web weights are 20 kg or 25 kg per bag. Customized packaging options are available upon demand.

Applications of CAS 9004-65-3 Hydroxypropyl Methyl Cellulose (HPMC) in Building And Construction Chemicals

Secret Duties in Structure Materials

Hydroxypropyl Methyl Cellulose (HPMC), identified by CAS number 9004-65-3, is a widely made use of cellulose ether in industrial building and construction. It works well in numerous dry-mix items since it blends quickly with water and various other components.

In ceramic tile adhesives, HPMC helps hold water so the concrete can heal correctly. This maintains the sticky solid and protects against tiles from slipping after placement. The product also makes the mix smooth and simple to spread out with a trowel.

For external insulation finishing systems (EIFS), HPMC boosts workability and maintains the skim coat from drying also fast. This offers workers more time to form and smooth the surface. It additionally enhances adhesion to insulation boards and reduces splitting.

Efficiency in Plasters and Provides

When added to plasters and makes, HPMC controls water retention. This makes sure also hydration of binders like cement or lime. Therefore, the last layer bonds far better to walls and reveals fewer surface area issues.

In self-leveling underlayments, HPMC acts as a thickener. It stops fragments from working out and aids the mix circulation evenly without dividing. This causes level, consistent floorings prepared for last flooring.

HPMC also supports spray-applied mortars. It offers the mix enough body to stay with upright surface areas without drooping. At the exact same time, it enables pumps to move the product efficiently via pipes.

Since it is secure across a series of temperature levels and pH levels, HPMC carries out reliably in different environments and task sites. Builders trust it to deliver regular results batch after set. Its non-ionic nature implies it does not respond badly with other typical additives in contemporary solutions.

5 FAQs of CAS 9004 65 3 Hydroxypropyl Methyl Cellulose HPMC for Industrial Use Construction Chemicals Cellulose Ether

Frequently Asked Questions About CAS 9004-65-3 Hydroxypropyl Methyl Cellulose (HPMC)

What is HPMC used for in construction?

HPMC is a key additive in many construction products. It helps improve workability, water retention, and adhesion. You will find it in tile adhesives, renders, plasters, and self-leveling compounds. It makes these materials easier to mix, apply, and finish.

Why is water retention important?

Good water retention keeps moisture in the mix longer. This allows cement or gypsum to hydrate fully. Without enough water, the material may crack or lose strength. HPMC holds water evenly so the final product cures properly and stays strong.

Does HPMC affect setting time?

Yes. HPMC can slightly slow down the initial set. This gives workers more time to place and smooth the material. The delay is controlled and does not harm final strength. In hot or dry conditions, this effect is especially helpful.

Is HPMC safe to handle?

HPMC is non-toxic and not classified as hazardous. Still, wear basic protective gear like gloves and a mask when handling powder form. Avoid breathing dust. Store in a cool, dry place away from moisture to keep quality stable.

How much HPMC should be added?

Dosage depends on the product type and performance needed. Typical use levels range from 0.1% to 0.5% by weight of total dry ingredients. Always follow the manufacturer’s instructions. Too little may not give full benefits. Too much can make the mix too thick or sticky. Test small batches first to find the right amount for your application.
