Abstract

The present invention relates to a corrosion resistant coating for metal reinforcing structures that are used in porous concrete which comprises coating the metal reinforcing structures with an organopolysiloxane elastomer obtained by crosslinking a diorganopolysiloxane-based composition by the condensation reaction or by the addition of Si-bonded hydrogen to an aliphatic carbon-carbon double bond, in which the composition contains a copolymer that is obtained via a free radical copolymerization of styrene and a (meth)acrylic acid ester in the presence of the diorganopolysiloxane.
