Abstract
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.
Claims16
A sealant composition comprising:
- a. between 12 wt % and 45 wt % of a hydrophilic binder;
- b. between 30 wt % and 80 wt % of a filler;
- c. optionally a thickener;
- d. between 10 and 50 wt % of water,
- wherein the composition has a pigment volume concentration (PVC) between 30% and 80%, and
- wherein the hydrophilic binder contains polar groups and the polar groups of the hydrophilic binder are one or more of hydroxyl, ester, carboxylic acid, amide, sulfate, phosphate, sulfosuccinate, urethane and isocyanate, and wherein the composition further comprises a silica sol of epoxy-silane surface modified colloidal silica in an amount of between 3 wt % and 14 wt %.
