<p>A two component paint composition that, after mixing, comprises the following components in aqueous solution: a) from the first component: i) an aqueous binder, which aqueous binder comprises an oligomeric or polymeric compound the oligomeric or polymeric compound being formed from at least one monomer of the general formula I: Si (OR1)4 where each R1 is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or -(C=O)R4 group, and each R4 group is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl or aryl group, and at least one monomer having the general formula II: (R2)4-mSi(OR3)m where each R2 is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl or aryl group, and wherein at least one -R2 group comprises the group -RXQRZ or -RXN(RW)2 where Rx is any C1 to C10 bivalent organic bridging group, Q is selected from an Oxygen or a Sulphur radical and Rz comprises an H, alkyl, alkenyl, alkynyl, aralkyl or aryl group, and each Rw is independently selected and defined as for Rz above; where each R3 is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or -(C=O)R5 group, where R5 is defined as for R4 above, and m = 1 to 3; and, optionally at least one colloidal silica; b) from the second component i) at least one reactive filler material.</p> |
