Fosroc Limited Penetrating Silane-siloxane Treatment Nitocote SN502

Nitocote SN502 is a single component penetrating silanesiloxane system which penetrates into porous substrates and then reacts to produce a bonded hydrophobic lining to the pores. Although allowing passage of water vapour from the substrate it significantly reduces the absorption of water and water borne salts. Nitocote SN502 does not discolour most substrates and has excellent resistance to weathering.
