A water resistant sealing material suitable as a gasket or valve seal is described. The sealing material comprises modified chemically exfoliated vermiculite (CEV) in a proportion of 30-70% w/w sealing material and a filler in a proportion of 70-30% w/w sealing material, and optionally other additives in a proportion of 0-10% w/w sealing material. The modified CEV comprises water resistance enhancing monovalent cations. The sealing material is particularly useful to provide improved water resistance in gaskets and valve seals.

Sealing material

The present invention provides a method for producing a solution of nanosheets, comprising the step of contacting an intercalated layered material with a polar aprotic solvent to produce a solution of nanosheets, wherein the intercalated layered material is prepared from a layered material selected from the group consisting of a transition metal dichalcogenide, a transition metal monochalcogenide, a transition metal trichalcogenide, a transition metal oxide, a metal halide, an oxychalcogenide, an oxypnictide, an oxyhalide of a transition metal, a trioxide, a perovskite, a niobate, a ruthenate, a layered III-VI semiconductor, black phosphorous and a V-VI layered compound. The invention also provides a solution of nanosheets and a plated material formed from nanosheets.
