4. Main Functions of mortar additive hpmc hydroxy propyl methyl cellulose hpmc:
a.Enhanced water retention-improved water retention can protect cement and plaster against
poor solidification and cracking due to speedy drying and inefficient mixing with water.
b.Workability-mortar plasticizing quality can be improved,which in return will improve the
workability of painting and working efficiency.
c.Binding-Dur to increased plasticizing quality,mortar can be a better binder.
d.Slipping resistance-Due to the thickening action of cellulose ether,the slipping phenomena of mortar from substance to bound can be prevented more efficiently.
5.Packaging: Multi-layer composite bag
1.Packed in polyethylene film bag enclosed in compositefilm bag.
2.Net weight of mortar additive hpmc hydroxy propyl methyl cellulose is 20 or 25kg per bag.
