Hydroxypropyl Starch ether HPS used as construction grade gypsum additive

Dry MORTAR STARCH ETHER
Description:
Starch ether 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 rheological behaviour of varied dry mortars based on cement and
gypsum. TMs-1 or TMs 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, e.g. redispersible polymer like surfactant, MC, starch, PVAC,
Etc.
Features and Benefits
• Improve sag resistance & anti-slap
• Optimize rheological behaviour, particularly the flow characteristics and workability
