HPMC powder,Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl methylcellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by using high purity cotton cellulose as a raw material and special etherification under alkaline conditions.
Hydroxypropyl Methyl Cellulose (HPMC) is a natural polymer cellulose material as raw material, through a series of chemical processes in the system of non-ionic cellulose ether. Methyl cellulose is an odorless, tasteless, non-toxic white powder, soluble in cold water to form a transparent viscous solution. A thickener, binder, dispersion, emulsion, film, suspension, adsorbing, gelling, surfactants, protective colloid and water holding characteristics.

HPMC powder,Hydroxypropyl Methyl Cellulose (HPMC)
Application in the construction and building industry:
1,cement mortar: improving cement - sand dispersion, greatly improving mortar plasticity and water retention, to prevent cracks have effect, can enhance the strength of cement.
2, tile cement: Increased repression tile mortar plasticity, water retention, improve tile glue relay, to prevent the powder.
3 coating, asbestos and other refractories: An agent as a suspension, fluidity improving agents, but also to improve the base rubber baton.
4, gypsum slurry coagulation: to improve water retention and workability, improve the adhesive force of the substrate.
5, joint cement: Added on joint cement used in gypsum board, improve mobility and water retention.
6, latex putty: to improve resin emulsion based putty mobility and water retention.
7, plaster: As a natural product instead of paste, it can improve water retention, increase with the base rubber baton.
8, coating: latex paint as a plasticizer to improve the coating operation performance and liquidity improved play a role.
9, spray paint: the prevention of cement-based or latex-based coating filler material to sink and had to improve liquidity and graphics spray beam with good results.
10, cement, gypsum secondary products: as a cement - asbestos and other water-based hydraulic binder material extrusion molding use, improve mobility, to get a uniform molded article.
11, fiber wall: Because DNase antibacterial action, as sand binder walls is effective.
12 Other: You can use as a thin clay and sand mortar plasterers operator action (PC version) bubble-retaining agent.
Packing and Storage
Standard Packing: In 25kg bags out HDPE bags inner with LDPE bags
Store it in a cool, dry place below 30degree and protected against humidity and pressing, since the goods is thermoplastic, storage time should not exceed six months.
