HPMC: Hydroxypropyl Methyl Cellulose

Hydroxypropyl Methyl Cellulose is a non-ionic cellulose ether made from natural high polymer cellulose. It is an odourless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution.

Hydroxypropyl Methyl Cellulose can be used in various building materials:

  • Tile adhesive
  • Cement mortar
  • Joint filler
  • Self-levelling compound
  • External wall insulation
  • Gypsum based plaster
  • Ceramic extrusion
