Product Description

Brif introduction
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.
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.

Product properties
• Improve sag resistance & anti-slap
• Optimize rheological behaviour, particularly the flow characteristics and workability
• Enhance adhesion strength
• Increase mortar yield
• Cost-effective. Obtain desired thickening effect with very low dosage. 

1.Internal and external wall putty powder
In lacquer putty, HPS is mainly to improve the construction and thixotropy of the putty, so that the operation is smooth.
2.Mortar and Tile adhesive                                                                        
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:
HPS can effectively improve the rheology of plaster and significantly improve sagging phenomenon for latter plastering and reduce the shrinkage and crack formation.
