1. Use directly-Mix under dry base:
MixHydroxypropyl methylcellulose with other materials you need to add directly in the mixer.
When Hydroxypropyl methylcellulose and other materials blend well,pour water to disperse and dissolve.
2. Mother solution first
First, pour 1/3 or 2/3 of the total water you need to add into the container.
Second, heat the water .when the water temperature is about 85 centigrade,add Hydroxypropyl methylcellulose continually at the same time keep stirring.
Third ,When the solution becomes a kind of slurry ,please add the rest of water while keep stirring until the solution turns transparent
1. Cement-based painting mortar
Hydroxypropyl methylcelluloset can improve the homogeneity of the mortar,which permits an easier painting of the mortar .Thus the working efficiency is improved and the resistance to sagging is enhanced.
The excellent water retention of Hydroxypropyl methylcellulose prolongs the workable time of putty,improves working efficiency ,avoids occurrence of crusting phenomena and imparts high mechanical strength to putty during coagulating period.
3. Heat-preservation mortar system's binding mortar and coating mortar
Hydroxypropyl methylcellulose can improve the homogeneity of the mortar,which permits an easier painting of the mortar .Thus the working efficiency is improved and the resistance to sagging is enhanced
4. Interface treatment binder
Hydroxypropyl methylcellulose improves the surface coating ,enhances the adhesiveness and increases the binding strength of mortar.
The excellent permeability improves the homogeneity of the interface
The high water retention rate prolongs the open time and improves the tile-pasting efficiency.
5. Gypsum-based mortar and gypsum products
Hydroxypropyl methylcellulosecan improve the homogeneity of the mortar,which permits an easier painting,higher working efficiency and resistance to sagging.
Our Hydroxypropyl methylcellulose is packed in an inner polyethylene bag reinforced with a 3-ply paper bag, or paper barrel or paper box, net weight is 25kg per bag.
