This powder also improves the adhesion of the material to its substrate, making the construction more robust and long-lasting. Moreover, the use of RDP powder also improves the workability of the construction materials by enhancing their viscosity, reducing segregation and bleeding. RDP powder has already gained widespread acceptance and popularity in many countries such as Peru, Bosnia and Herzegovina, Palestine, Philippines, and Singapore, among others. Its superior quality, reliability, and performance have made it the go-to construction material for many professionals in the industry. If you are looking for RDP powder for construction projects in Brazil, you can trust in the quality and performance of this product. Its effectiveness in enhancing the durability, workability, and adhesion of construction materials makes it a valuable investment in any construction project. In conclusion, the need for high-quality construction materials in Brazil has been increasing over the years, and RDP powder is among the essential materials that cannot be left out. With its proven quality and performance, it has won the hearts of many professionals in the construction industry from various countries, including Peru, Bosnia and Herzegovina, Palestine, Philippines, and Singapore. Invest in RDP powder today, and take your construction projects to the next level.

Application

Hydroxyethyl cellulose（HEC）

The most important property of hydroxyethyl cellulose powder is that it acts as a thickener, in creasing the viscosity of the liquid,and its thickening depends on its concentration. If you're searching for a versatile solution that enhances the performance of your products, look no further than Hydroxyethyl Cellulose (HEC) powder.

Gypsum Special Grade HPMC

The gypsum special grade hydroxypropyl methyl cellulose HPMC has the characteristics of high water retention, dispersibility, good fineness, good workability and easy dissolution. widely used in gypsum products like gypsum plaster, adhesive plaster, embedded gypsum, tile adhesives etc.

Daily Chemical Products Additive

Daily Chemical HPMC has a variety of properties such as thickening, foam stabllization,emulifiation, and easy dispersion. Shampoo Additive HPMC has good compatibility with various additives of other daily chemical products. It is widely used in detergents, shower gels, shampoos, hand sanitizers, and laundry liquid and other products.

Tile Adhesive Additive

Tile Adhesive Additive HPMC can ensure the smooth construction on difterent base surtaces, even when the ambient temperalure is relalively harsh, the tile adhesive can be given a long enough open time and adjustable time.

Gypsum Additive

In gypsum products, the focus is on water retention, retardation and lubrication. Different gypsum has different effects on product performance, so thickening, water retention, and retardation determine the quality of gypsum building materials.

Mortar Additive

Adding hydroxypropyl metylellulose can improve anti-sip performance, improve wetting performance, thicken, improve batch scraping and slipping, easy to level, improve surface performance and strength, and have very good compatibility with other additives.

Putty Powder Additive

Hydroxypropyl metylcellulose is a commonly used raw material in powdered building materials, which greatly improves the slip performance and anti-sag performance of the construction, improves the wettability, improves the anti-slip performance of the putty, improves the leveling effect of the putty, and improves the construction eficlency.

Technical Guidelines for Hydroxypropyl Methylcellulose (HPMC)

As a professional manufacturer of architectural-grade HPMC, we provide you with comprehensive technical guidance and problem-solving support throughout the production and application processes.

How much do you know about Hydroxypropyl methyl cellulose(HPMC)?

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether obtained by cellulose alkalization, etherification, neutralization and washing. HPMC has good thickening, dispersing, emulsifying, film-forming properties, etc.It is the first choice for production of high quality building materials additives.

How to improve the adhesion of putty

When encountering the projects that have been constructed, it is found that the adhesion of putty on the exterior wall is poor, the following methods can be adopted to improve the adhesion of putty:

Dissolution Method

Take the required amount of hot water into the container and heat to above 85., stir slowly and add the product gradually The cellulose initially floats on the water, but gradually disperses in water and forms homogeneous slurry. Goon stirring until it cools down and becomes clear

Faq

HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?

1. Hot water dissolution method: HPMC does not dissolve in hot water, but it can disperse evenly in hot water initially and then rapidly dissolve upon cooling. There are two typical methods described as follows: (1) Place the required amount of hot water in a container and heat it to approximately 70°C. Gradually add HPMC while stirring slowly. Initially, HPMC will float on the water's surface and gradually form a slurry, which cools down under stirring. (2) Add 1/3 or 2/3 of the required amount of water to a container and heat it to 70°C. Disperse HPMC according to method (1) to prepare a hot water slurry. Then, add the remaining cold water to the hot water slurry and cool the mixture after stirring. 2. Powder mixing method: Mix HPMC powder with a large amount of other powdered substances using a blender. Afterward, add water for dissolution. In this case, HPMC can dissolve without clumping because each tiny corner of the powder contains only a small amount of HPMC, which dissolves immediately upon contact with water. This method is commonly used in putty powder and mortar production.

What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?

For putty applications, a lower viscosity of 100,000 is sufficient, and good water retention is important. For mortar applications, higher viscosity of 150,000 is preferred. For adhesive applications, a high-viscosity, quick-dissolving product is required.

What are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?

HPMC has three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any reaction. The formation of bubbles in putty powder can be caused by two reasons: (1) Excessive water content. (2) Applying another layer on top before the bottom layer has dried, which can also lead to the formation of bubbles.

Regarding the relationship between viscosity and temperature in HPMC (HPMC viscosity), what should be noted in practical applications?

In simple terms, "non-ionic" refers to a substance that does not ionize in water. Ionization refers to the process in which electrolytes dissolve in specific solvents (such as water or alcohol) and dissociate into freely moving charged ions. For example, table salt we consume daily—sodium chloride (NaCl)—when dissolved in water, ionizes and produces freely moving sodium ions with a positive charge and chloride ions with a negative charge. In other words, when HPMC is placed in water, it does not dissociate into charged ions but exists in molecular form.
