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.
