HPMC is a type of non-ionic cellulose ether, white powder appearance, odorless and tasteless, soluble in water and most polar organic solvents. Its water solution has a surface activity, high transparency, stable performance. HPMC has a thermal gel properties, after heating, the product solution formed the gel precipitation, dissolving after cooling. Different specifications products have different gel temperature. Solubility changes with viscosity's difference. The lower viscosity, the higher solubility, different specifications HPMC have difference in properties, dissolving HPMC in water won't be affected by PH value.
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials

Product Description Redispersible polymer powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate-ethylene (VAE), and then obtained a free flowing organic polymer powder. It can re-disperse in water, and form a film after water evaporation by coalescence of individual polymer particles. The film acts as an organic binder, to glue together different substrates, reinforce mortar structure and provide excellent adhesion at cement or gypsum based dry mixed mortar substrate interface.

HPMC For Construction HPMC for construction is a non-ionic cellulose ether obtained by alkalization, etherification, neutralization and washing of cellulose.HPMC powder has good properties of thickening, dispersing, emulsifying and film-forming, and it is the first choice for the production of high-quality building material additives. The use of hydroxypropyl methyl cellulose in construction In construction, putty powder is used in very large quantities. About 90% of HPMC in construction is used as putty powder additives, and the rest is cement mortar and glue, used as thickening and water retention agents. The amount of HPMC chemicals CAS9004-65-3 added to construction materials is very low, only 0.1%-1%, but it plays an irreplaceable role, which can significantly improve the water retention, fluidity and lubricity of construction materials. Building materials with added HPMC cellulose are easier to mix and use, improving the efficiency of construction workers, extending open time, improving bond strength, and forming a smooth and delicate surface coating. - Construction HPMC powders are used in cementitious mortars and grouts to improve ease of use, adhesion and water retention. - Hydroxypropyl methyl cellulose is also used in self-leveling compounds, tile adhesives and grouts to improve flow and workability. -Construction HPMC is commonly used as a binder and thickener in coatings and paints. - HPMC binders are also used in gypsum-based materials such as wallboard and ceiling tiles to improve workability and reduce water absorption.
Interior ordinary putty powder is mainly used for leveling walls, since it is not waterproof, should be the surface to brush the paint, or will cause a large area off the powder, affect the appearance. This product can use within water directly, without glue. It has advantages as strong adhesion, easy to burnish, reserving powder, no wrapper, no crack, no bubble, low price. Apply to interior wall with full of batch.Mainly used as a paint primer leveling.
Property: Pva is a very versatile water-soluble polymer, performance is between plastic and rubber, appearance is white powder.Water is a good solvent pva.Pva has good membranous, to form the film with excellent, frictional resistance, stretching intensity, and oxygen insulated.Because pva with two functional groups of hydrophilic group and hydrophobic group, therefore has the interfacial activity, so the pva can be used as a polymer emulsion and suspension polymerization reaction of protective colloid. Cas no:9002-89-5 ec no:209-183-3 melting point:230-240âºc falshing point:79âºc molecular formula:(c2h4o)n Application: 1 the textile industry as a processing location between the cloth and the machine agent. 2 the paper industry as a pigment coating engineering cement and paper glue inside. 3 powder chemical building materials, such as ceramic tile adhesive, interface agent, the thin layer of putty, stucco gypsum, adhesive plaster, etc. Water resistant crack thickener.
