Steel sheet coating compositions in which polymeric resin or ceramic properties are produced by admixing an aluminum coordinate complex and an aluminum resin, a polysilazane as a source of silicon, an organic solvent, an organic synthesis catalyst, and optionally a non-metallic, non-ionic, low-nucleophilic base. The admixed coating is applied to sheet steel prior to hot-stamping in order to inhibit surface formation of iron oxides and to improve steel sheet surface characteristics.

A film is provided with void spaces having a porous structure with less cracks and a high proportion of void space as well as having strength. The film with void spaces includes one kind or two or more kinds of structural units that form a structure with minute void spaces, wherein the structural units are chemically bonded through catalysis. For example, the abrasion resistance measured with BEMCOT® is in the range from 60% to 100%, and the folding endurance measured by the MIT test is 100 times or more. The film with void spaces can be produced by forming the precursor of the silicone porous body using sol containing pulverized products of a gelled silicon compound and then chemically bonding the pulverized products contained in the precursor of the silicone porous body. The chemical bond among the pulverized products is preferably a chemical crosslinking bond among the pulverized products.

The present invention relates to a ceramized silicone resin composition and a pre-preg and a laminate that use the composition. The ceramized silicone resin composition comprises: 50-100 parts of a condensation-type silicone resin, 0.0001-2 parts of a catalyst, 5-80 parts of a ceramic-forming filler, and 0.01-50 parts of a flux. The pre-preg and the laminate manufactured using the ceramized silicone resin composition, when used in a sustained high temperature, can transform into complex ceramized structure thereby providing ceramic properties, thus providing great fireproof and flame retardant effects; also, manufacturing of the laminate is similar to that of a regular FR-4 laminate, where the process is easy to operate. The ceramized silicone resin composition, the pre-preg, and the laminate have the advantages of being halogen-free, low smoke, low toxicity, flame retardant, and fireproof, provide a novel concept and a novel method in terms of flame retardancy and fire resistance, accelerate the research progress in laminate passive fire protection technology, and have broad prospects in the field of fire protection and fire resistance.
