Application of HPMC in the Building Materials Product Industry

1. Building mortar plastering mortar
Water retention can fully hydrate cement, significantly increase bonding strength, and appropriately increase tensile and shear strength, greatly improving construction efficiency and work efficiency.

2. Waterproof putty
Cellulose ether in putty mainly serves to retain water, bond, and lubricate, avoiding cracking and dehydration caused by rapid water loss. At the same time, it enhances the adhesion of putty and reduces sagging during construction, making the construction smoother and more successful.

3. Painting gypsum series
In the gypsum series products, cellulose ether mainly plays a role in water retention, thickening, lubrication, etc., and also has a certain retarding effect, solving the problems of bulging and cracking during construction and insufficient initial strength, which can extend the working time.
4. Interface agent
Mainly used as a thickener, it can improve tensile strength and shear strength, enhance surface coating, and strengthen adhesion
And bonding strength.
5. External wall insulation mortar
