what's kind thickener should be used in mortar
HPMC is a non-ionic ,water soluble cellulose ether that form films, water-retentions, stability, adhesiveness, especially widely used for construction materials because it is chosen to enhance adhesion, water retention, and lubricity, shrink and crack resistance. Modified cellulose ethers improve on the slippage, brittle resistance to pressure and tensile sex. Therefore, for cement and plaster based motors, will be your best choice. It's white or off-white powder ,non-toxic tasteless, and readily soluble in hot or cold water.
HPMC is odorless, tasteless,non-toxic cellulose ethers produce 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 protective colloid properties of surface activity and maintain moisture function properties ect
