Product Description

Product Description

Product Description Hydroxypropyl starch ether

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.

Recommend Applications:

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.

Starch ether is starch based additives designed for dry mortars in building industry. These starch ethers can improve the performance and optimize the workability of dry mortar by modifying the thickness and rheology of varied dry mortars based on cement and gypsum. Starch ether should be used in combination with cellulose derivatives. It can well perform in neutral and alkaline conditions, and it is compatible with other additives in gypsum or cement based building materials.
