Visflow VH series is a new generation Polycarboxylate ether based multi range plasticizer based on expertise hybrid polymers technology. It is a water reducing as well slump retarding polymer (ASTM C 494 -Type D).It gives excellent Rheology and self-compacting concrete. Due to steric-hindrance effect imparted by ether-function hydrophilic grafted chain attached to polymer, superior initial workability and later on retention is achievable by use of Visflow VH.
