RAPIDLY ACTING DRY SEALANT AND METHODS FOR USE AND MANUFACTURE

摘要

Disclosed herein is a dry solid sealant matrix composition comprising: · a first cross-linkable component; · a second cross-linkable component that cross-links with the first cross-linkable component under reaction enabling conditions; and · a hydrogel-forming component; wherein the concentration of combined first and second cross-linkable components is from 5 to 75% of the total mass of the composition and the concentration of the hydrogel forming component is from 25 to 95% of the total mass of the composition; and wherein under reaction-enabling conditions the first and second cross-linkable component cross-link to form a porous matrix having interstices, and wherein the hydrogel-forming component is capable of being hydrated to form a hydrogel to fill at least some of the interstices.
