Hydroxypropyl methyl cellulose HPMC has good thickening, dispersing, emulsifying, film-forming properties, etc. It is the first choice for production of high quality building materials additives.
In building materials, the addition amount of HPMC is very low, only 0.1%-1%, but it plays an irreplaceable role.
EIFS(Exterior insulation and finish system) can also named ETICS(External Thermal Insulation Cladding System) is a building cladding systems that provides exterior walls with an insulated, waterproof, finished surface in an integrated composite material system. HPMC plays an essential role in this application with the key properties of high sag resistance and long embedding time, etc.
