Abstract

Abstract A heat-resistant paint comprising a dispersion or solution of a polymetallocarbosilane and an inorganic filler in an organic solvent, wherein said polymetallocarbosilane is an organometallic polymer having a number average molecular weight of 400 to 50,000 comprising (A) carbosilane bond units of the formula ##STR1## wherein R 1 and R 2 may be identical or different and each represents a lower alkyl group, phenyl group or a hydrogen atom, and (B) metalloxane bond units of the formula (M--O) wherein M represents at least one element selected from the group consisting of Ti, Zr, Cr and Mo, wherein said inorganic filler is at least one material selected from the group consisting of oxides, borates, phosphates, silicates, silicides, borides, nitrides and carbides; and wherein said inorganic filler is present in an amount of 10 to 900 parts by weight per 100 parts by weight of said polymetallocarbosilane.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 269 words
A heat-resistant paint comprising a dispersion or solution of a polymetallocarbosilane and an inorganic filter in an organic solvent, wherein said polymetallocarbosilane is an organometallic polymer having a number average molecular weight of 400 to 50,000 comprising (A) carbosilane bond units of the formula ##STR3## wherein R 1 and R 2 may be identical or different and each represents a lower alkyl group, a phenyl group or a hydrogen atom, and (B) metalloxane bond units of the formula --M--O-- wherein M represents at least one element selected from the group consisting of Ti, Zr, Cr and Mo, and optionally at least a part of each of the above elements has at least one lower alkoxy group or a phenoxy group as a side-chain group, in which the bond units (A) and (B) are bonded at random in the main-chain skeleton, and/or at least one of the silicon atoms of the bond units (A) is bonded to each of the above elements of the bond units (B) via an oxygen atom, whereby the polycarbosilane portion obtained by chaining of the bond units (A) is crosslinked with the bond units (B), and in which the ratio of the total number of the bond units (A) to the total number of bond units (B) is in the range of from 1:1 to 10:1; wherein said inorganic filter is at least one material selected from the group consisting of oxides, borates, phosphates, silicates, silicides, borides, nitrides and carbides: and wherein said inorganic filler is present is an amount of 10 to 900 parts by weight per 100 parts by weight of said polymetallocarbosilane.
Claim 2
Dependent Claim 269 words
A heat-resistant paint comprising a dispersion or solution of a polymetallocarbosilane and an inorganic filter in an organic solvent, wherein said polymetallocarbosilane is an organometallic polymer having a number average molecular weight of 400 to 50,000 comprising (A) carbosilane bond units of the formula ##STR3## wherein R 1 and R 2 may be identical or different and each represents a lower alkyl group, a phenyl group or a hydrogen atom, and (B) metalloxane bond units of the formula --M--O-- wherein M represents at least one element selected from the group consisting of Ti, Zr, Cr and Mo, and optionally at least a part of each of the above elements has at least one lower alkoxy group or a phenoxy group as a side-chain group, in which the bond units (A) and (B) are bonded at random in the main-chain skeleton, and/or at least one of the silicon atoms of the bond units (A) is bonded to each of the above elements of the bond units (B) via an oxygen atom, whereby the polycarbosilane portion obtained by chaining of the bond units (A) is crosslinked with the bond units (B), and in which the ratio of the total number of the bond units (A) to the total number of bond units (B) is in the range of from 1:1 to 10:1; wherein said inorganic filter is at least one material selected from the group consisting of oxides, borates, phosphates, silicates, silicides, borides, nitrides and carbides: and wherein said inorganic filler is present is an amount of 10 to 900 parts by weight per 100 parts by weight of said polymetallocarbosilane.
