External Thermal Insulation and Finish Systems (ETIFS) and External Thermal Insulation Composite Systems (ETICS)
ETIFS and ETICS are the kind of thermal insulation structure which is installed on the surface of exterior wall.
Now in order to improve the living standards that modern building need to do the insulation property . it can reduce the influence of thermal bridge and deformation stress on the base wall. At present, the most commonly used is to paste a layer of foam polystyrene board on the straight line of the exterior wall surface, and then apply a layer of surface mortar on the outside, but the bonding performance of foam polystyrene board and surface mortar is poor.However, adding cellulose ether in mortar can not only increase the binding force between them, but also can easily improve the workability and water holding capacity of mortar, making mortar not easy to crack.our hpmc cellulose can give effectively improvement on the water retention, anti-stress cracking, open time, sag resistance, workability of the ETICS mortars.
In construction & building materials ,
Hydroxypropyl Methyl Cellulose (HPMC) can be used as dispersant, thickener and adhesive, and the
HPMC cellulose is mainly used for cement mortar,ETIFS and ETICS . the cellulose used in buildings , it can increase the adhesive , reduce flocculation , improve the viscosity , shrinkage and the water retention, reduce water loss on concrete surface , improve strength, prevent the occurrence of cracks and weathering of water-soluble salt.
The advantages of our hpmc cellulose to use in the ETIFS and ETICS
(1)Enhance the adhesives, especially for EPS/XPS and mineral fiber board.
(2)Increases cohesion
(3)Improves the wear resistance of the surface
(4)Prevents cracking
(5)Prolongs durability
