Hydroxypropyl Methyl Cellulose HPMC for tile adhesive cement based, plaster cement and cement mortar
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
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.
5.Packaging: Multi-layer composite bag
1.Packed in polyethylene film bag enclosed in compositefilm bag.
2.Net weight of HPMC is 20 or 25kg per bag.
6. Application of HPMC
Plasters, Renders, & Stucco:
Keep the product un-stacked in dry and closed rooms at normal temperature and air humidity. To achieve best possible results, we recommend storage under the condition stated above and use within 12 months from delivery. Avoid breathing duct when handling, and wash with soap & water in case of skin contact.
