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.
