CheV^TM  HYDROXYPROPYL STARCH ETHER
CheV
Hydroxypropyl starch ether(abbr.HPS) is nonionic and has high stability
of substituting ether bond. In the process of hydrolysis, oxidation,
dextrinizing and cross-linking reaction, ether bond cannot be broken and
it can replace the group and does not fall off. It is a kind of
chemical modified starch ether, which is mainly used as thickener and
texturing agent for cement or gypsum based mortar products.
 
CheV HPS is a cost-saving material and is easy to obtain the required
thickening effect. During the application of wet mortars, it gives
non-sag, anti-slip properties and good workability and low stickiness.
 
PHYSICAL SPECIFICATIONS

RECOMMENDED APPLICATION & PROPERTITY IN MORTAR
 
1.Internal and external wall putty powder
In lacquer putty, CheV HPS is mainly to improve the construction and thixotropy of the putty, so that the operation is smooth.
2.Mortar and Tile adhesive                                                                        
CheV HPS improves mortar adhesion and balance of open time and anti-slip
for tile adhesive. It has the characteristics of good fluidity,
excellent film-forming properties, retrogradation weak and viscosity
stability.
3.Gypsum plaster:
CheV HPS can effectively improve the rheology of plaster and
significantly improve sagging phenomenon for latter plastering and
reduce the shrinkage and crack formation.
