Advantage Of Hydroxypropyl Starch Manufacture and ...

HPS is a kind of ionic hydroxypropyl starch ether, which is produced by a series of chemical and physical reactions with starch as raw material. It is a kind of non-toxic, tasteless white or beige power, which can be dissolved in cold water to form transparent or translucent viscous liquid. It is effective in thickening, adhesion, dispersion, emulsification, suspension, adsorption, surface activity, water retention and so on.  ETON Hydroxypropyl starch ether is a kind of chemical modified starch mainly used as thickener and texturing agent for cement or gypsum based mortar products.

Hydroxypropyl Starch Ether

SE-301

Hydroxypropyl Starch Ether can impart unique properties to cement and gypsum based products. It has the similar chemical structure with Hydroxypropyl Methylcellulose(HPMC) that not only provide Hydroxypropyl Methylcellulose(HPMC)-like function, but also has good compatibility with other building additives. In combination with Hydroxypropyl Methylcellulose(HPMC), Hydroxypropyl Starch Ether can play a better thickening effect, with better crack resistance and improve workability. And by adding starch ether, the cost of the mortar formulation can be significantly reduced.

The properties of starch ether in dry mortar are as follows:

1. Due to the special chemical structure of starch ether, Hydroxypropyl Starch Ether can effectively prevent the hanging phenomenon of thick layer of mortar, which has a good improvement effect on the sliding of the tile, the hanging of thick layer and other undesirable phenomenon;
2. Adding appropriate amount of Hydroxypropyl Starch Ether in the mortar can delay the opening time of it. The water retention of starch ether can be kept stable with the increase of temperature. Therefore, the product can not only improve the water retention performance of the mortar, but also compensate the rapid retention of the water retention capacity of the ordinary water retention agent with the increase of the temperature;
3. Hydroxypropyl Starch Ether has a fast thickening function for mortar, which can improve the rheology of spray mortar and plaster mortar;
4. Hydroxypropyl Starch Ether can effectively prevent the stratification/segregation of the mortar, which can be well used in self-leveling mortar;

Hydroxypropyl starch ethers are added in the following materials:

1. Inner and outer wall putty powder of various types(cement, gypsum base);
2. Various types of(tile, stone) binders;
3. All kinds of facing mortar and plaster mortar, especially the exterior wall insulation mortar.
