redispersible polymer powder for India
redispersible polymer powder (RDP) has revolutionized the construction industry in India. With the growing demand for sustainable and eco-friendly alternatives, RDP has become an essential ingredient in various products, including dry-mix mortars, plasters, and tile adhesives.
RDP is a copolymer powder that disperses in water and creates a film-like material to provide water retention, flexibility, and increased adhesive strength. It plays a crucial role in reducing cracking, improving flexibility, and enhancing the overall quality and durability of building materials.
India's growing construction industry has increased demand for RDP, which is widely used in cementitious systems to enhance the mortar's properties such as workability, adhesive strength, crack resistance, and durability. Furthermore, it acts as a binder, and the coating's redispersibility makes it an excellent choice for self-leveling compounds.
RDP is an eco-friendly alternative that replaces traditional polymers such as polyvinyl acetate (PVA), which have a negative environmental impact. It is non-toxic and biodegradable, making it ideal for sustainable construction in India.
Our RDP products, known for their consistent quality and performance, are sold globally and used in India and other countries, including Morocco, Malta, Rwanda, Bosnia and Herzegovina, and the United States. Our focus on innovation and staying up-to-date with the latest developments in the industry enables us to maintain our expertise, experience, authoritativeness, and trustworthiness.
In conclusion, the increasing demand for sustainable and eco-friendly construction materials has led to a surge in RDP usage in India. Our high-quality redispersible polymer powder has become an ideal choice due to its exceptional properties, including increased water retention, flexibility, and adhesive strength. Its eco-friendly nature makes it an ideal choice for sustainable construction in India and worldwide, including Morocco, Malta, Rwanda, Bosnia and Herzegovina, and the United States.

Regarding the relationship between viscosity and temperature in HPMC (HPMC viscosity), what should be noted in practical applications?
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.
What is the main use of 1-Hydroxypropyl methylcellulose (HPMC)?
The dosage of HPMC in actual application varies depending on factors such as climate, temperature, local lime and calcium quality, putty powder formulation, and the desired quality specified by the customer. Generally, it ranges between 4 kg to 5 kg. For example, in Beijing, most putty powders use around 5 kg; in Guizhou, it is mostly 5 kg in summer and 4.5 kg in winter; in Yunnan, the dosage is smaller, usually around 3 kg to 4 kg, and so on.
What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?
The two main indicators most users are concerned about are the content of hydroxypropyl and viscosity. Higher hydroxypropyl content generally indicates better water retention. A higher viscosity also provides relatively better water retention (not absolute), and HPMC with higher viscosity is more suitable for cement mortar.
How to judge the quality of HPMC?
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.
