RDP powder for Brazil
Construction projects have been increasing over the years in Brazil, and with that, the demand for high-quality construction materials has also been on the rise. One of the essential materials for construction is
RDP powder. This powder is an essential component for many construction applications, including plaster, exterior and interior walls, and dry-mix mortars, among others.
RDP powder is a white, free-flowing, high-performance powder that improves the workability, adhesion, and durability of construction materials. It is made from high-quality raw materials that undergo advanced processing to produce a product that meets the highest standards required in the construction industry.
One of the benefits of using RDP powder is that it enhances the strength and durability of the construction materials. 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.

How to judge the quality of HPMC?
The powder loss in putty is mainly related to the quality of the lime powder and has little to do with HPMC. Low calcium content in lime powder and an improper ratio of CaO and Ca(OH)2 in lime powder can both cause powder loss. If there is a slight relationship with HPMC, it would be that poor water retention of HPMC can also contribute to powder loss.
What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?
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 are the main raw materials of Hydroxypropyl Methylcellulose (HPMC)?
HPMC produced using solvent methods uses solvents such as toluene and isopropanol. If the washing process is not thorough, there may be some residual odor.
What is the main function of HPMC in putty powder and does it undergo a chemical reaction?
Hydroxypropyl Methyl Cellulose, in English: Hydroxypropyl Methyl Cellulose, also known as HPMC or MHPC. Other names: Hydroxypropyl Methyl Cellulose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose; Cellulose, 2-hydroxypropylmethyl Cellulose ether; Cellulose hydroxypropyl methyl ether; Hyprolose.
