Compositions, methods, and kits are provided for sealing applications. Compositions are prepared by combining a first cross-linkable component with a second cross-linkable component to form a porous matrix having interstices, and combining the porous matrix with a hydrogel-forming component to fill at least some of the interstices. The compositions exhibit minimal swelling properties.本發明係提供密封應用的組成物、方法和套組。藉著將第一個可交聯之組份與第二個可交聯之組份組合,形成具有間隙的多孔基質,並將該多孔基質與形成水凝膠的組份組合,充滿至少一些間隙,製備組成物。該組成物展現出最低的膨脹性。
