Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose used in building materials, which can be dissolved in hot or cold water to form a transparent solution with a specific viscosity.
Normally HPMC is widely used in dry-mixed mortar industry, ceramic tile binder, external insulation system, self-leveling mortar, plastering, putty, paint and so on, it can improve construction performance, water retention performance, bond strength and sagging resistance.
Hydroxyethyl cellulose(HEC) is a gelling and thickening agent derived from cellulose. HEC is non-ionic, water-soluble materials that provide good properties of thickening, suspending, binding, emulsify, film-forming, stabilize, disperse, retain water and etc. And It is widely used in coatings, construction, papermaking and polymer polymerization industries.
Hydroxypropyl Starch are a starch-based additive designed for dry mortars in the building industry. These starch ethers can improve the performance and optimize the workability of dry mortar by modifying the thickness and rheology of varied dry mortars based on cement and gypsum.� Starch� ether� should be used in combination with cellulose derivatives. It can well perform in neutral and alkaline conditions, and it is compatible with other additives in gypsum or cement-based building materials.
