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.

What are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?
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 dosage of Hydroxypropyl Methylcellulose (HPMC) 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 is the main function of HPMC in putty powder and does it undergo a chemical reaction?
1. Interior wall putty powder: Heavy calcium carbonate 800KG, light calcium carbonate 150KG (Starch ether, pure Qing, Peng run soil, citric acid, polyacrylamide, etc., can be added as appropriate).
2. Exterior wall putty powder: Cement 350KG, heavy calcium carbonate 500KG, quartz sand 150KG, latex powder 8-12KG, cellulose ether 3KG, starch ether 0.5KG, wood fiber 2KG.
What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?
HPMC can be divided into two types: instant soluble and heat soluble. Instant soluble HPMC quickly disperses in cold water, disappearing in the water. At this stage, the liquid does not have viscosity because HPMC is only dispersed in the water and not completely dissolved. After about 2 minutes, the viscosity of the liquid gradually increases, forming a transparent and viscous colloidal solution. Heat soluble HPMC tends to agglomerate in cold water but can rapidly disperse in hot water, disappearing in it. As the temperature decreases to a certain point, viscosity slowly appears until a transparent and viscous colloidal solution is formed. Heat soluble HPMC can only be used in putty powder and mortar, as it tends to agglomerate in liquid adhesives and coatings and cannot be used effectively. Instant soluble HPMC has a wider range of applications and can be used in putty powder, mortar, liquid adhesives, and coatings without any restrictions.
