Cellulose ethers can widely used as thickening agents and water retention agents in constructioon materials.It can also be used in adjusting the consistence,developing workability,prpolonging open time and increasing the adhesion.
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.
STORAGE
Keep in a dry place away from heat and sunlight,
store in sealed containers.
