Patent ID: 8129028

Claim:
A two component paint composition that, after mixing, comprises the following components in aqueous solution: a) a first component comprising: 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(OR 1 ) 4 I where each R 1 is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or —(C═O)R 4 group, and each R 4 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: (R 2 ) 4-m Si(OR 3 ) m II where each R 2 is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl or aryl group, and wherein at least one —R 2 group comprises the group —R X QR Z or —R X N(R W ) 2 where R X is any C 1 to C 10 bivalent organic bridging group, Q is selected from an Oxygen or a Sulphur and R Z comprises an H, alkyl, alkenyl, alkynyl, aralkyl or aryl group, wherein R Z optionally comprises at least one epoxy functional group or at least one carbonyl functional group, and each R W is independently selected and defined as for R Z above; where each R 3 is independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, or —(C═O)R 5 group, where R 5 is defined as for R 4 above, and m=1 to 3: and, optionally at least one colloidal silica; b) a second component comprising: i) at least one reactive filler material, the reactive material comprising zinc oxide; provided that the paint composition comprises less than 20% by weight of or panic solvent.
