1.Brief Introduction

HPMC-Hydroxypropyl Methyl Cellulose and Methyl Hydroxyethyl Cellulose and non-ionic cellulose ether made by natural high polymer cellulose as raw material and series of chemical processing. They are odorless, tasteless and non-toxic white powder, which can be dissolved in cold water to form a transparent viscous solution. Processing thickening, binding, dispersing, emulsifying, film, coating, suspending, absorbing, gelling, surface activity, water maintaining and protective colloid properties.

3.HPMC for EIFS:

ETIFS(External Thermal Insulation and Finish Systems)/ETICS(External Thermal Insulation Composite Systems)
ETIFS/ETICS is a kind of thermal insulation structure which is installed on the surface of exterior wall. It can reduce the influence of thermal bridge and deformation stress on the base wall. LANDCEL products can give effectively improvement on the water retention, anti-stress cracking, open time, sag resistance, workability of the ETICS mortars.

HPMC for EIFS Typical Applications

Adhesive mortar
Coating mortar
Thermal mortar

HPMC for EIFS Advantages

Enhance the adhesives, especially for EPS/XPS and mineral fiber board.
Increases cohesion
Improves the wear resistance of the surface
Prevents cracking
Prolongs durability
