Hydroxypropyl Methyl Cellulose HPMC for Wall Putty
Hydroxypropyl methyl cellulose HPMC for wall putty
1. Product Introduction
Cellulose ether HPMC is a non-ionic, water soluble white powder. It can be used as an agent of water retention, thickening, adhesive and dispersing, and also plays a role of protective colloid, stabilizer,suspension and film forming.
HPMC Hypromellose Cellulose is odorless, tasteless,nontoxic cellulose ethers producted from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility.
It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.
Hydroxypropyl methyl cellulose HPMC is widely used in tile adhesives, wall putty/skim coat, plaster/render mortars, EIFS, tile grouts, joint filler, self leveling compounds, detergents, ready to use paints and coatings, etc.
1. Pharmaceutical grade: this product is mainly used for pharmaceutic adjuvant that can be used as a thickener, dispersing agent, emulsifier and film-forming agent etc. When used as film coating and adhesive in drug tablets, it can significantly improve the waterproofing of tablets. Besides, it can also be used as suspension, ophthalmic preparation, slow and controlled release agent skeleton and floating tablets etc..
HPMC is combined with colloidal drugs as other synthetic polymers in order to prevent the separation of water and ethanol from transparent water and colloidal materials and improve water retention; and it is also used in food, cosmetics and other fields as thickener, emulsifier and to improve the rheological properties as well as other daily chemical industries, etc.
2. Industrial grade: industrial grade
HPMC is mainly used as dispersant in PVC production and is also the main additive of PVC preparation for suspension polymerization. In building construction, it is mainly used for external wall thermal insulation system, thermal insulation mortar, decoration mortar, masonry mortar and selfleveling mortar etc.. It is used as thickener, stabilizer, emulsifier, excipient, water retaining agent, filmforming agent etc. in the production of petrochemical products,paint remover, agricultural chemicals, printing ink, textile printing and dyeing, ceramics, papermaking, cosmetics and other products. When it is applied to synthetic resin, the products obtained will be of characteristics such as regular and loose particles, suitable apparent specific gravity and good processing properties etc., which can essentially replace gelatin and polyvinyl alcohol as dispersant.
Besides, during the decorative construction, it is mainly used for building walls, stuccoing, caulking and other mechanized construction; especially in decorative construction, it can be used to paste ceramic tile, marble and plastic decoration, which is of high adhesive strength and can also reduce the amount of cement. When used as thickener in coatings industry, it can make the coating light and delicate without taking-off of powder and improve leveling performances etc.
