Melacoll™ HPMC Highlights
- Cold-water solubility. HPMC dissolves easily in cold water, reducing your waiting time.
- Thickness. Increases viscosity and stability of liquids.
- Water retention. Extending the open time also helps cement hydration more fully.
- Lubrication. HPMC for cement can improves workability and processing.
- PH stability. Melacoll™ HPMC remains stable in the range of pH 3~11.
- Non-ionic. It is more stable in an aqueous solution.
- Thermal gelation. HPMC turns into a gel when the temperature is too high, and when cools down, it turns into the liquid again.
- Air entraining. HPMC for mortar helps increase production and improve workability.
- Film formation. Hydroxy Propyl Methyl Cellulose is waterproof and oil-proof.

What is your recommended HPMC grades for waterproofing mortar?
Waterproofing mortar: MP45000 with viscosity 40000-55000
The grade promises a good fluidity and excellent water retention
Formula to this grades: for 1 ton of the Water resistance wall putty or mortar, you need 1.5-2 kg of HPMC/HEMC
| Reference formular for Waterproof mortar | |
| Weight(kg) | Materials |
| 450 | Ordinary Portland cement 42.5 |
| 520 | Sand (30-80 mesh/0.10-0.80m) |
| 20-25 at least | Re-dispersible Polymer Powder(RDP) ET3060 |
| 1.5-2 | HPMC MP45000 |
| 2 | Water repellent |
| 1-2 | Superplasticizer |
| 1-2 | Defoamer powder |
| 1000 | |
What do you recommended HPMC grades according to tile adhesive?
0.2.5-0.3 % HPMC MP70000 or HEMC ME70000
Our MelaColl and Mikrant products are high-performance additives widely used in cement applications. The addition of our performance additives in mortars or concretes can significantly enhance its processing feature and final product performance.
How do you ensure your HPMC quality?
Our happy customers say everything. Customers will establish a long-term cooperative relationship with us. Plus the supervisor from the U.S. headquarters will regularly send QC inspectors to supervise our Production line( We have a quality prosecutor resident for long in the Chinese market. They are strict at every level ).
Considering the Pandemic in recent months, all the quality inspections are carried out by local reports and conducted online. But there was no slack. We will send samples for random inspection regularly. If it fails, we will be required to limit the output.
Why is the viscosity of your product higher than Dow or Ashland and Lotte?
The difference in viscosity between the two products is because Melacoll and Walocel adopt different production processes and raw materials. WALOCEL uses fine wood cotton, which determines its good water retention. While MELACOLL, using** refined cotton** as the raw material, has a thickening property twice that of ordinary products.
The intention we designed the high viscosity products is for saving customers' expenses. When the viscosity is high, the dosage does not need to be too large, which saves our clients' expenses.
Do you have FDA, BFR or GB for your HPMC product ?
At present, our products are mainly of construction grade and daily chemical grade. We will develop food grade and pharma grade in the future.
Why do we add 2% HPMC according to your TDS the detergent is not transparent?
2% dosage is the proportion to test the Brucelloy viscosity by water solution, which is not the actual dosage.
How many a container contains of HPMC?
