HPMC main function:
1. Water retention---improved water retention can protect cement and plaster against poor solidification and cracking due to too speedy drying and inefficient mixing with water.
2. Workability --martar plasticizing quality can be improved, which in turn will improve the workability of painting and working efficiency.
3.Binding---Due to the increased plasticizing quality , mortar can be a better binder.
4.Slipping-resistance---Due to the thickening action of Cellulose Ether, the slipping phenomena of mortar from substance to be bound can be prevented more efficiently.
