RDP powder for Russia
RDP powder for Russia: Revolutionizing Construction Materials
When it comes to construction materials, there is one key ingredient that is gaining increasing popularity for its versatility and affordability – RDP powder. Short for Redispersible Polymer Powder, RDP powder has revolutionized the manufacturing and construction industry with its ability to enhance the properties of building materials such as cement, tile adhesives, and plasters. And now, this game-changing material is available in Russia.
RDP powder is a fine, white powder that is obtained by spray-drying polymer emulsions. It is a highly stable and water-soluble material that has excellent re-dispersibility in water, making it an ideal additive for many construction applications. With its ability to improve the durability, flexibility, and workability of building materials, RDP powder has quickly become a go-to choice for many builders and manufacturers worldwide.
One of the main benefits of RDP powder is its versatility. It can be used in a wide range of applications, from wall putty and ceramic tile adhesives to exterior insulation finishing systems and self-leveling compounds. It is also highly resistant to water, heat, and freeze-thaw cycles, making it ideal for use in harsh environments.
But the benefits of RDP powder extend beyond just its physical properties. It can also aid in cost savings for builders and manufacturers by decreasing the amount of raw materials needed and increasing the shelf life of the finished product. Furthermore, it is an eco-friendly option since it reduces the amount of waste generated during the manufacturing and construction process.
Russia has now joined the list of countries that have access to RDP powder, including Morocco, Bosnia and Herzegovina, Malta, and the United States. With its growing popularity in the construction industry, RDP powder is sure to be in high demand in Russia as well, especially in its booming construction market.
In conclusion, RDP powder is a game-changing material that has taken the manufacturing and construction industry by storm. Its versatility, durability, and eco-friendliness make it an ideal choice for builders and manufacturers worldwide. Now, with its availability in Russia, builders and manufacturers in this region can also reap the benefits of this innovative product.

Several dissolution methods of Hydroxypropyl methyl cellulose (HPMC)
For putty powder, a viscosity of around 100,000 is generally sufficient, while mortar requires a higher viscosity, around 150,000, to be effective. Moreover, the most important function of HPMC is water retention, followed by thickening. In putty powder, as long as it has good water retention and a lower viscosity (70,000-80,000), it can still be used. Of course, a higher viscosity provides relatively better water retention. However, when the viscosity exceeds 100,000, the impact of viscosity on water retention becomes less significant.
HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
In the application of HPMC in putty powder, it plays three roles: thickening, water retention, and facilitating construction. Thickening: Cellulose can thicken the mixture, maintain uniform suspension, and prevent sagging. Water retention: It slows down the drying process of putty powder and assists in the reaction of lime and calcium in water. Construction: Cellulose acts as a lubricant, improving the workability of the putty powder. HPMC does not participate in any chemical reactions; it only serves as an auxiliary agent. When putty powder is mixed with water and applied to the wall, a chemical reaction occurs because new substances are formed. However, if the putty powder is scraped off the wall, ground into powder, and reused, it is not suitable because a new substance (calcium carbonate) has already formed. The main components of lime and calcium powder are Ca(OH)2, CaO, and a small amount of CaCO3. The reaction can be represented as: CaO + H2O = Ca(OH)2 — Ca(OH)2 + CO2 = CaCO3 ↓ + H2O. Under the action of water and carbon dioxide in the air, lime and calcium carbonate are formed. HPMC only assists in water retention and the better reaction of lime and calcium; it does not participate in any reactions itself.
What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?
The main raw materials for Hydroxypropyl Methylcellulose (HPMC) include refined cotton, chloromethane, epichlorohydrin, and other materials such as soda ash, acid, toluene, isopropanol, etc.
What are the formulations for interior and exterior wall putty powder?
HPMC is widely used in industries such as construction materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, agriculture, cosmetics, and tobacco. HPMC can be classified into architectural grade, food grade, and pharmaceutical grade based on its application. Currently, most domestically produced HPMC falls under the architectural grade category. In the architectural grade, a large amount of HPMC is used in putty powder, accounting for approximately 90% of its usage, while the rest is used in cement mortar and adhesives.
