MHEC powder for Indonesia
MHEC powder- The Solution to Indonesia's Building Construction Struggles
Indonesia, a country with a growing demographic and developing economy, requires a significant revamp that involves critical infrastructure development. To achieve this goal, developers are continuously challenging themselves to build durable buildings, bridges, and other assets to cater to the needs and protect the country's growing population. In recent years there has been a shift in the construction market as experts are now opting to use MHEC powder to improve their building construction.
MHEC powder is a new addition to the building material market that enhances the properties of cement and improves the workability of construction solutions. It is a type of cellulose-based ether powder that is free-flowing, white, and odourless. MHEC powder has a significant influence on hydraulic cement, as it functions as a water retention agent and thickener. Due to its exceptional properties, it is now becoming a popular solution for Indonesia's construction industry.
One of the main reasons why MHEC powder is the perfect solution for Indonesia is its compatibility with different cement types. MHEC powder works with Portland cement, Slag cement, and pozzolanic cement. This property is advantageous for the Indonesian construction industry because the country uses different types of cement for different types of constructions.
MHEC powder has a high demand worldwide, and the product is popular in countries such as Malta, United States, Palestine, Morocco, and Singapore. It is an indicator that MHEC powder is an excellent solution for different climate zones, humidity levels, and environmental conditions.
In conclusion, it is essential for construction experts in Indonesia to recognize the benefits of MHEC powder and incorporate it into their building structures. The demand for unique and more complex infrastructures is increasing, and MHEC powder presents an opportunity to enhance building functionalities. By using MHEC powder, the construction industry in Indonesia can build better, stronger, and more long-lasting structures, while meeting the growing demand for sustainable development in the country.

What is the main function of HPMC in putty powder and does it undergo a chemical reaction?
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 recommended viscosity 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.
What is the dosage of Hydroxypropyl Methylcellulose (HPMC) in putty powder?
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.
What are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?
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.
