Hydroxypropyl Starch Ether

Hydroxypropyl starch ether is a starch-based additive designed for dry mortars in the construction industry, imparting unique properties to cement and gypsum-based products.

Hydroxypropyl starch ether, which has a similar chemical structure to hydroxypropyl methylcellulose (HPMC), not only provides similar functions to hydroxypropyl methylcellulose (HPMC), but also has good compatibility with other building aids. Capacitance. Used in conjunction with hydroxypropyl methylcellulose (HPMC), hydroxypropyl starch ether can play a better thickening effect, with better crack resistance and processability. It works well in neutral and alkaline conditions and is compatible with other additives in gypsum or cement-based building materials. The cost of mortar formulations can be significantly reduced by adding starch ethers.

Specification of Hydroxypropyl Starch Ether

Properties of Hydroxypropyl Starch Ether

●  Hydroxypropyl Starch Ether can improve sagging resistance with its anti-sagging properties and optimize workability;

● Hydroxypropyl Starch Ether can effectively prevent the drape phenomenon of mortar thick layer, and has a good effect on improving the unfavorable phenomena such as tile sliding and thick layer drape;

● Adding an appropriate amount of Hydroxypropyl Starch Ether to the mortar can delay its opening time. The water retention of starch ethers remained stable with the increase of temperature. Therefore, the product can not only improve the water retention performance of the mortar, but also compensate for the rapid retention of the water retention capacity of ordinary water retention agents with the increase of temperature;

● Hydroxypropyl Starch Ether has a rapid thickening effect on mortar, which can improve the rheology of spray mortar and plastering mortar;

● Hydroxypropyl Starch Ether can effectively prevent mortar delamination/segregation, and can be well used in self-leveling mortar;

Application of Hydroxypropyl Starch Ether

● Tile Adheisve-C2

● Wallputty (Interior & Exterior)

● Block Joint Mortar

● ACC Adhesive Mortar

● Manufacturing of glues and adhesives
