A sealant composition having between 30 wt % and 60 wt % of a dispersion of a hydrophilic binder; between 30 wt % and 70 wt % of a filler; between 0.05 wt % and 1 wt % of a thickener, wherein the pigment volume concentration (PVC) is between 40% and 80%. A method for preparing such a sealant composition.

Sealant composition

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(OR)where each Ris independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or &#x2014;(C&#x2550;(O)Rgroup, and each Rgroup 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)Si(OR)where each Ris independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl or aryl group, and wherein at least one &#x2014;Rgroup comprises the group &#x2014;RRor &#x2014;RN(R)where Ris any Cto Cbivalent organic bridging group, Q is selected from an Oxygen or a Sulphur radical and Rcomprises an H, alkyl, alkenyl, alkynyl, aralkyl or aryl group, and each Ris independently selected and defined as for Rabove; where each Ris independently selected from hydrogen or any alkyl, alkenyl, alkynyl, aralkyl, aryl or &#x2014;(C&#x2550;O)Rgroup, where Ris defined as for Rabove, and m=1 to 3; and, optionally at least one colloidal silica; b) from the second component i) at least one reactive filler material.
