Product Description

Hydroxy Propyl Methyl Cellulose HPMC 
HPMC is non-ionic cellulose ether produced from natural molecular cellulose through series of chemical changes. They are characterized by the solubility in water, water retain, stable PH value, surface activity, reversibiltity from gelling and solving in different temperature, thickening, binding, film-forming, lubricatinf and mols resistance.

Main Functions of HPMC used for Wall Putty 

1.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.
2.Workability-mortar plasticizing  quality can be improved,which in return will improve the
    workability of painting and working efficiency.
3.Binding-Dur to 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 bound can  be prevented more efficiently.
