MelaColl™ HPMC series have different viscosity and properties. HPMC is a versatile chemical addictive. Its uses include three ways: construction, daily chemical, food, and pharmacy. In this article, we will talk about Melacoll HPMC grades and uses.
For more information, please visit tile adhesive wall putty chemical hpmc.
MelaColl™ HPMC’s raw material is refined cotton. The refined cotton endows HPMC with good thickening properties. This is twice that of ordinary people. So it ensures Melacoll HPMC‘s viscosity is higher than DOW or Ashland and Lotte.
Melacoll HPMC manufacturing process is through etherification between propylene oxide, Chloromethane, and another chemical. Melacoll provides a complete supply chain. Its headquarter is in Dallas, Us. The US lab continues to innovate and research new products. We have many experienced R & D personnel. Besides, keep pace with market demand. Put the customer's opinion first.
Our customers are mainly engaged in the construction industry. Like tile adhesive, and wall putty. joint compound, Melacoll HPMC will play a good function. Learn more about Melacoll HPMC grades and uses that can ensure produce good use effects. We have another blog with some questions about cellulose ether and RDP grades from our customs.
Of course, Melacoll continues to upgrade formulas, like tile adhesive formula or wall putty formula. Adopt different HPMC grades to pursue application tests. Using this way to test Melacoll HPMC quality. There are so many HPMC grades in Melacoll. This article mainly focuses on MP 400, MP 20000, MP 45000, and MP 70000.
1.MELACOLL HPMC GRADES AND USES
MelaColl™ MP 400
MelaColl™ MP400 is a non-ionic, water-soluble cellulose ether. Its viscosity is low, but it can provide good correction and fluidity. This feature is very practical for self-leveling. Self-leveling mortar is the free flow of cement slurry according to the height of the terrain to achieve a high leveling effect.
MelaColl™ MP 400 utilizes self-leveling to have the following advantages:
Ensure the fluidity of self-leveling mortar
Form a smooth surface
Reduce shrinkage and increase load-bearing capacity
Improve the adhesion between self-leveling mortar and base
MelaColl™ MP 45000
MelaColl™ MP 45000 is a non-delayed dissolving hydroxypropyl methylcellulose. After dissolving in water, it plays a role in various properties. Wide range of applications, including tile adhesives, putty, fillers, insulation systems, gypsum base, etc. This requires him to have moderate sag resistance and thickening properties. The viscosity range of this product is between 40000-55000.
This product has the following advantages:
Enhance the thickening effect
Improve adhesion. When used in tile adhesive, it strengthens the adhesiveness between the tile and the substrate and prevents the tile from hollowing, slipping, and cracking.
Improve water retention and prolong open time
MelaColl™ MP 70000
MelaColl™ MP 70000 is also a non-delayed dissolution hydroxypropyl methylcellulose ether. Its viscosity ranges from 65000 MPa to 75000 MPa. MelaColl™ MP 70000 has good anti-sagging properties. Excellent water retention and high tile adhesion. Customers are mainly used in Tile adhesive, Concrete adhesive; EIFS adhesive; Gypsum adhesive..
A thickener, binders, surfactants, protective colloids, suspending agents, and water retention agents in many construction materials.
MelaColl™ MP 20000
MelaColl™ MP 20000 is a non-ionic, water-soluble hydroxypropyl methylcellulose. Its viscosity is about 15,000 to 25,000. It belongs to non-delayed dissolution. Can be used for tile adhesive, putty, caulk, etc. When used in caulk, it will help remove almost all imperfections from sentimental surfaces.

In addition, we have other HPMC grades and applications. And we are developing new product formulations, and updating new product grades and usage. Please follow our latest blog content. If you have any needs, you can contact our sales staff.
Brif introduction
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.
Product properties
1. Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
2. Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
3. Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
4. Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
