Hydroxypropyl methylcellulose
HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.
HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
1.HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural high molecular cellulose through series of chemical processing and achieved.
2 It is white powder with good water solubility.It has thickening, adhesion, dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and main moisture function properties etc.
Hydroxypropyl Methyl Cellulose HPMC used for Cement Plaster / Dry mix mortar:
•HPMC easy dry mix formula due to cold water solubility:Lump formation can be easily avoided, ideal for heavy tiles.
•Good water retention:Prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.
•Increased water demand:Increased open time, expanded spry area and more economical formulation.
•HPMC easier spreading and improved sagging resistance due to improved consistency.
