HPMC is white powder or granule made from highly pure cotton -
cellulose by reaction of etherification under alkal. HPMC is
characterized by water solubility, water retention, nonionic,
stability of the PH value, surface activity, temperature reversible
gelling properties, thickening property, film formability,
lubrication property etc.,without any organs of animals, fat and
other bioactive constituents.

HPMC Main Function
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
3. Binding-Dur to increased plasticizing quality,mortar can be a
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.
