Abstract
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 —RXRZ 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 R…
