Hydroxypropyl Starch Ether (HPS)

Hydroxypropyl Starch Ether (HPS)

SLEO® SL-HPS is a kind of ionic hydroxypropyl starch ether, which is produced by a series of chemical and physical reactions with starch as raw material. SLEO® SL-HPS is a kind of non-toxic, tastelesswhite or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid. It is effective in thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on. And it is well compatible with other additives in gypsum or cement based building materials.

– Skim coat / wall putty

– Tile adhesives

– Joint fillers

– Cement mortar/Masonry mortar

– Cement based plasters

– External insulation and finish systems (EIFS)

– Grout
