Hydroxypropyl Starch Ether
Product Description
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.
, which has a similar chemical structure to hydroxypropyl methylcellulose (HPMC), not only provides similar functions to , 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.
