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 is the main use of 1-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.
HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
1. Whiteness: Although whiteness alone does not determine the usefulness of HPMC, higher-quality products usually have better whiteness.
2. Fineness: HPMC is typically available in 80 and 100 mesh sizes, with fewer options in 120 mesh. Finer particles generally indicate better quality.
3. Transmittance: When HPMC is dissolved in water and forms a transparent colloidal solution, higher transmittance indicates fewer insoluble impurities.
4. Specific gravity: Higher specific gravity is generally better. A higher specific gravity is often due to a higher content of hydroxypropyl, which results in better water retention.
What is the application of HPMC in putty powder, and what causes the formation of bubbles in putty powder?
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 are the differences between HPMC and MC?
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.
