Sika® Air - LS
Sika® Air-LS is an air-entraining agent based on synthetic surfactants. It is a diluted version of Sika® Air and therefore performs and fulfils the same function as Sika® Air but at higher dose rates, to enable more accurate dosing. Its efficiency is based upon the entrainment into the mix of a high number of correctly sized and evenly distributed air bubbles.
