CAS No.:9004-65-3
Property:

White fibrous or granular powder. 

Carbonization temperature: 280-300℃.
Soluble in water and some solvents, such as appropriate ratio of ethanol and water, propanol and water, trichloroethane, etc. Aqueous solutions are surface active, high transparency, stable performance. The gel temperature of products with different specifications is different. Solubility changes with viscosity, the lower the viscosity, the greater the solubility.
Usage:

1. Construction: as a water-retaining agent and retarder of cement mortar, the mortar has pumping property. Apply mortar, plaster, putty powder or other building materials as a binder to improve spreadability and extend operation time.
