Masterseal 380 

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.
