RDP chemical for Indonesia
Indonesia is a country that is known for its rapid industrialization and modernization. In order to keep up with the pace of development, chemical additives are required in various sectors such as construction, textiles, and coatings. The use of
RDP chemical is one such requirement that has become essential in the Indonesian market.
RDP, or Redispersible Polymer Powder, is a versatile chemical that is used extensively in the construction industry. It is primarily used as a binder, and can be easily mixed with other materials to enhance their bonding properties. RDP chemical is also used in the production of coatings and sealants, providing a high level of water resistance and increased durability.
With the growing demand for RDP chemical in Indonesia, it has become imperative to ensure that the right quality products are available in the market. To achieve this, the RDP chemical manufacturers are continually improving their technologies and processes to meet the local requirements.
One of the most significant advantages of using high-quality RDP chemical is the improvement in the strength and durability of the final product. This is particularly important in construction projects, where safety and longevity are critical factors.
Apart from Indonesia, RDP chemical is used widely across the globe. Countries such as Rwanda, Palestine, Malta, and the United States are also major markets for this chemical. In fact, the increasing demand for eco-friendly and cost-effective building materials has led to a surge in the use of RDP chemical throughout the construction industry.
In conclusion, Indonesia's modernization and expansion present significant opportunities for the growth of the RDP chemical market. By choosing the most reliable and high-quality RDP chemical suppliers, buyers can ensure the safety, durability, and quality of the final product. With the growing demand for RDP chemical globally, it is imperative to make the right choices and stay ahead in the industry.

What are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?
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.
What are the main technical indicators of Hydroxypropyl Methylcellulose (HPMC)?
The viscosity of HPMC is inversely proportional to temperature, meaning that viscosity increases as temperature decreases. When we refer to the viscosity of a certain product, it generally refers to the measurement result of its 2% water solution at 20 degrees Celsius.
In practical applications, in regions with large temperature differences between summer and winter, it is advisable to use relatively lower viscosity during winter for better construction. Otherwise, at low temperatures, the viscosity of the cellulose increases, resulting in a heavier feel during application.
Medium viscosity: 75,000-100,000 (mainly used for putty)
Reason: Good water retention.
High viscosity: 150,000-200,000 (mainly used for polystyrene particle insulation mortar powder and foamed glass bead insulation mortar)
Reason: High viscosity, reduces mortar dusting and sagging, improves construction.
However, in general, higher viscosity provides better water retention. Therefore, many dry mortar manufacturers consider using medium-viscosity cellulose (75,000-100,000) instead of low-viscosity cellulose (20,000-40,000) to reduce the dosage and costs.
Is there any relationship between powder loss in putty and HPMC?
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.
How to judge the quality of HPMC?
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.
