Brief Introduction
Hydroxypropyl Methyl Cellulose (HPMC) is non-ionic cellulose ether made from natural polymer cellulose through series
of chemical processes. It contains almost all properties of methyl cellulose (MC) and is the first choice for the production of
high-quality building materials additives. HPMC has the characteristics of thickening, dispersing, emulsifying, film forming,
suspension, adsorption, surface activity, moisture retention and protective colloid. It is suitable for dry mortar, tile adhesive,
wall putty, skim coat, caulking compound, interface agent, coating, and self-leveling agent for new building materials.
HPMC Properties
1. Water Retention
Water retention will be improved, which helps to solve the problem of cement or gypsum construction materials
drying too fast and poor hardening or cracking due to insufficient hydration.
2. Workability
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.

We provide customers with the following services:
• Help customers find matching products quickly.
• Customized production based on samples provided by customers.
• Suggestions for formula improvement. We can help customers provide suggestions for improving formulations based on
local climate conditions, building material properties and construction habits to improve product performance and control costs.
We have chemical lab and application lab to ensure the best satisfaction for each order.
• Chemical lab can help us evaluate product properties such as viscosity, humidity, ash content, PH value, methyl and hydroxy
-propyl content, substitution degree, etc.
• Application lab can help us measure open time, water retention, adhesive strength, slip resistance and sag resistance,
setting time, workability, etc.
