1. What is the main purpose of HPMC?

——Answer: HPMC is widely used in building materials, tile adhesives, wall putty, dry-mixed mortar, gypsum plaster, self-leveling,coating and paint, detergent, etc.

2. How to judge the quality of HPMC simply and intuitively?

1) Whiteness, although whiteness cannot determine whether HPMC is easy to use, and if whitening agents are added in the production process, it will affect its quality, but most of the good products have good whiteness.

2) Fineness: The fineness of HPMC generally has 80 mesh and 100 mesh, 120 mesh is less, the finer the finer the better.

3) Light transmittance: After HPMC is placed in water to form a transparent colloid, look at its light transmittance. The greater the light transmittance, the better, indicating that there are less insolubles in it, and the transmittance of vertical reactors is generally good. , The horizontal reactor is worse, but it does not mean that the quality of the vertical reactor is better than that of the horizontal reactor, and there are many factors to determine the product quality.

4) Specific gravity: The larger the specific gravity, the heavier the better. The higher the specific gravity, the higher the hydroxypropyl content in the product. The higher the hydroxypropyl content, the better the water retention.

3. What are the main technical indicators of HPMC?

——Answer: Hydroxypropyl content and viscosity, most users are concerned about these two indicators. Those with high hydroxypropyl content generally have better water retention. Those with high viscosity have better water retention, relatively rather than absolutely, and those with high viscosity are better used in cement mortar.

4. What is the appropriate viscosity of HPMC?

——Answer: Wall putty generally has a viscosity of 100,000, and tile adhesives generally have a viscosity of 150,000 or 200,000. Moreover, the most important function of HPMC is water retention, followed by thickening. In putty powder, as long as the water retention is good, a lower viscosity of 70,000 to 80,000 is also acceptable. Of course, the higher the viscosity, the better the relative water retention. When the viscosity exceeds 100,000, the viscosity has little effect on water retention.

5. What are the main raw materials of HPMC?

—— Answer: The main raw materials of HPMC: refined cotton, methyl chloride, propylene oxide, and other raw materials, caustic soda, acid, toluene, isopropanol, etc.

6. What is the gel temperature of HPMC related to?

The company is the world’s best hpmc for wall putty powder supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

——Answer: The gel temperature of HPMC is related to its methoxy content. The lower the methoxy content↓, the higher the gel temperature.

Gomez Chemicals is a manufacturer of cellulose ether and redispersible polymer powder. We focus on technology, quality and customer service, and provide customers with high-quality and stable products and perfect technical services, allowing customers to reduce production costs while improving product quality.

In the production of building materials, especially dry mixed mortar, cellulose ether plays an irreplaceable role. Especially in the production of special mortar (modified mortar), is an indispensable and important part:

1. Easy mixing without lump formation

Mikazone cellulose ethers as additives are vital when dry powder products are mixed by hand. The lubricating properties of cellulose ethers reduce friction between particles, saving time and making thorough dispersion easier.

2. Improved workability

The lubricity of Mikazone HPMC improves workability, making spreading easier and increasing efficiency.

3. Good water retention

HPMC increases the water retained by the adhesive, minimizing the amount absorbed by the substrate and by the tile. This prolongs open time and brings gains in productivity because the adhesive can be applied to a wider area. Mikazone cellulose also can extend the shelf life and pot-life of ready-mixed adhesives, prolonging their usefulness.

4. Enhanced adhesion and sliding resistance

Mikazone cellulose products enhance adhesion, even at high ratios of water to solids, ensuring a better result and preventing sagging. Mikazone HPMC can help your products resist sliding, a benefit that tile setters will appreciate.
