Description

An optimum concentration of reactive hydrophobic silane-siloxane in a hydrocarbon solvent carrier. MasterSeal 380 provides a protective impregnating treatment. MasterSeal 380 works by penetrating into the pores of concrete and reacting there with the moisture / water vapour present to form a hydrophobic polysiloxane lining to the capillaries. ​
