HP7501 HPMC with enhanced properties

HP7501 cellulose ether is a kind of non-ionic, water-soluble polymer powder that is developed to improve working ability of dry mixed mortars such as Tie adhesive CIT Adhesion and embedding mortar for ETICs Gypsum plaster Skim coat Special applications of mortar and concrete Dosage of total dry mixed mortar 0.15-0.45% Typical performance Good wetting and troweling ability Good slip resistance Good water retention Easy to obtain a smooth surface Good compatibility with other additives Storage and delivery HP7501 cellulose ether belongs to of hygroscopic and hydrophilic polymer powder, so it should be stored and delivered under dry and clean conditions in its original package form and away from heat. After the package is opened for production, tight re-sealing must be taken to avoid ingress of moisture. Shelf life At least 2 years under cool and dry condition. For material storage over shelf life, quality confirmation test should be done before use. Product safety According to EU legislation on dangerous substances and preparations, HP7501 cellulose ether does not belong to hazardous material. Further information on safety aspects is given in Material Safety Data Sheet.
