What is the recommended viscosity of Hydroxypropyl Methylcellulose (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.
HPMC is a non-ionic type of cellulose ether. So, what does "non-ionic" mean?
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 are the formulations for interior and exterior wall putty powder?
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 are the other names for Hydroxypropyl Methyl Cellulose (HPMC)?
The gelation temperature of HPMC is related to its methoxy content. The lower the methoxy content, the higher the gelation temperature.
