High Viscosity HPMC for Putty – Anti-Sag & Crack Resistance | QingQuan

QingQuan Cellulose makes a high viscosity grade of Hydroxypropyl Methyl Cellulose (HPMC) specifically for putty. This additive increases the body and thixotropy of putty, so it won't sag on vertical walls. It also holds water well, giving you more working time and a smooth, tough finish that resists cracking.

Product Description

What is HPMC?

Hydroxypropyl Methylcellulose (HPMC) is a nonionic cellulose alkyl hydroxyalkyl mixed ether. It's made from cellulose through alkalization, etherification, neutralization, and washing.

HPMC in Cement Mortar

HPMC does a lot of jobs in construction materials. You can add it to masonry mortar, plastering mortar, stucco, and plastering paste. Even a small amount makes a big difference. In cement and gypsum plasters, HPMC holds water, which leads to stronger bonds and harder plaster after curing.

Good water retention lets cement hydrate fully. That means stronger bonds, better tensile and shear strength in hardened mortar, and easier handling. Construction goes smoother and faster.

When you're working with cement mortar, you need good water retention. Bricks and walls soak up water quickly, and mortar usually has a lot of sand. Without enough water retention, bricks pull water out too fast. The mortar loses water in spots, and the cement doesn't hydrate fully. Mortar made with sand, lime, and cement has low natural bond strength. But add cellulose ether, and bond strength goes way up – even under heavy loads or sideways stress.

Applications

Water-Resistant Putty

In water-resistant putty, cellulose ether holds water, improves adhesion, and adds slip. It stops cracks and powdering from fast water loss. It also cuts down on sagging, so application is smoother, takes less effort, and gives you more control.

Plastering

In gypsum products, cellulose ether provides water retention, thickening, and lubrication. It also slows things down just a little, which stops bulging and cracking during application. It also keeps initial strength from failing and gives you longer working time.

Interfacial Agents

HPMC works mainly as a thickener here. It boosts tensile and shear bond strength, improves surface coating, and increases adhesion.

Tile Adhesives

HPMC holds water well. When you're putting up tiles, you don't need to soak or pre-wet them. Bond strength goes way up. The mix stays fine and uniform, so you can work longer and it's easier to apply.

Slurry Spraying

Spray slurry with cellulose works well for protecting interior and exterior walls, roofs, floors, and tunnels. Cellulose creates a kind of combing effect in the spray material. It increases cohesion and adhesion, stops cracking, and makes the sprayed layer more waterproof and durable.

Daily-Use Chemicals

You'll find HPMC in cosmetics, shampoos, shower gels, and other daily products. It thickens well, forming a colloid with water molecules. It makes products thicker and easier to apply. It also holds moisture, absorbing and retaining water.

Caulking

Adding HPMC gives good edge bonding, low shrinkage, and high wear resistance. It protects the base material from damage and stops water from soaking into the building.

Self-Leveling Cement Mortar

Use low viscosity HPMC in self-leveling cement mortar. It improves flow, speeds up application, and gives high surface strength after drying with low shrinkage.

Latex Paints

In paint, HPMC works as a film-former, thickener, emulsifier, and stabilizer. It gives paint films better wear resistance, uniformity, and adhesion. It also improves surface tension and keeps pH stable.

Gypsum Decorative Materials

Gypsum products are light, insulate heat, resist fire, and help control indoor temperature. Adding HPMC lets gypsum hydrate fully, ensures good bonding, and stops cracks.

Ceramic Heat Storage Materials

Adding cellulose ether to new ceramic heat storage materials improves lubricity and water retention during mold making. Parts come out less deformed and stronger.

Oil Drilling Fluids

Cellulose ether works as a gel polymer, fluid loss preventer, and friction reducer to help recover more oil. It helps mud form a stable suspension. Using HPMC in oil drilling improves mud performance, speeds up drilling, and cuts pollution.

FAQ

What are your prices?
Prices change based on availability and market conditions. Contact us for an up‑to‑date price list.

Can you provide documentation?
Yes. We can provide most documents, including certificates of analysis, conformity certificates, and other export papers. We also offer solid after‑sales service.

How is shipping cost calculated?
It depends on the shipping method. Express is fastest but most expensive. Sea freight works best for large volumes. We need quantity, weight, and method to give you an exact cost. Contact our sales team.
