Claims19
A mixture curable to provide an intumescent coating material, wherein the mixture comprises:
- a silane-terminated polymer,
- a cross-linker for curing the silane-terminated polymer,
- an epoxy resin, wherein the epoxy resin is different from the silane-terminated polymer and wherein the epoxy is not a plasticizer,
- a cross-linker for curing the epoxy resin, and
- an intumescent package, wherein the intumescent package comprises a phosphorus containing compound, a gas source, and a carbon source,
- wherein the ratio of silane-terminated polymer to epoxy resin is 1:1,
- wherein the proportion of the intumescent package is greater than the proportion of the epoxy resin in the mixture, and
- wherein the mixture curable to provide an intumescent coating material is a two-part mixture, and wherein a first part of the two-part mixture comprises the epoxy resin and the intumescent package, and a second part of the two-part mixture comprises the silane-terminated polymer, the cross-linker for curing the silane-terminated polymer, and the cross-linker for curing the epoxy resin.
An intumescent coating for protecting a substrate, the intumescent coating comprising an intumescent coating material, wherein the intumescent coating material is the cured reaction product of a mixture comprising:
- a silane-terminated polymer,
- a cross-linker for curing the silane-terminated polymer,
- an epoxy resin, wherein the epoxy resin is different from the silane-terminated polymer and wherein the epoxy resin is not a plasticizer,
- a cross-linker for curing the epoxy resin, and
- an intumescent package, wherein the intumescent package comprises a phosphorus containing compound, a gas source, and a carbon source,
- wherein the proportion of the intumescent package is greater than the proportion of the epoxy resin in the mixture wherein the proportion of the intumescent package is greater than the proportion of the silane terminated polymer in the mixture, and
- wherein the mixture is a two-part mixture, and wherein a first part of the two-part mixture comprises the epoxy resin and the intumescent package, and a second part of the two-part mixture comprises the silane-terminated polymer, the cross-linker for curing the silane-terminated polymer, and the cross-linker for curing the epoxy resin.
A mixture curable to provide an intumescent coating material, wherein the mixture comprises:
- a silane-terminated polymer,
- a cross-linker fur curing the silane-terminated polymer,
- an epoxy resin, wherein the epoxy resin is different from the silane-terminated polymer and wherein the epoxy resin is not a plasticizer,
- a cross-linker for curing the epoxy resin, and
- an intumescent package, wherein the intumescent package comprises a phosphorus containing compound, a gas source, and a carbon source, and
- wherein the proportion of the intumescent package is greater than the proportion of the epoxy resin in the mixture and wherein the proportion of the intumescent package is greater than the proportion of the silane terminated polymer in the mixture, and
- wherein the mixture curable to provide an intumescent coating material is a two-part mixture, and wherein a first part of the two-part mixture comprises the epoxy resin and the intumescent package, and a second part of the two-part mixture comprises the silane-terminated polymer, the cross-linker for curing the silane-terminated polymer, and the cross-linker for curing the epoxy resin.
