Effect
A. Water retention---Improved water retenton can protect cement and plaster against poor solidification and cracking due to too speedy drying and inefficient mixing with water.
B.Workability---Mortar plasticizing quality can be improved, which in turn will improve the workability of painting and working efficiency.
C.Binding---Due to the increased plasticizing quality, mortar can be a better binder.
D.Slipping-resistance---Due to the thinckening action of Cellulose Ether, the slipping phenomena of mortar from substance to be bound can be prevented more efficiently.
Note
1.Highest viscosity shall be obtained by completely mixing or agitating both before and after the addition of the product.
2.Direct addition of the product with surface treatment into alkaline water solution will lead to the failure of the surface treatment, resulting in gel. Therefore, product with surface treatment can not be added into the alkaline water solution directly.
3.Tht concerntration of the prepared solution shall be determined according to the product viscosity. The solution concentration of product with low viscosity(lower than 100mPa.s)is 10~15%,and the solution concentration of product with high viscosity(more than 30000mPa.s)is 2-3% at most.
