Abstract
The present invention relates to a novel, heat-resisting layer-constructions consisting of base substrates such as plates, boards and sheets, and silicone polymers having high contents of aryl radicals painted and thermally cured to adhere on the surfaces of the said base substrates, and the method of preparing the same. Starting materials of the said silicone polymers are polyaralkylsiloxanes in which the molar ratio of aryl radicals are: aryl radicals/(aryl radicals+alkyl radicals)=0.65 to 1, i.e., from 65 to 100 molar percent, and the functionality of the polymerizable functional groups is as average between 2 and 3. Most of the silicone polymer thin films coated and strongly adhered on to the surface of the said substrates are colorless and transparent, and all the polymer films have high resistivity against heat, light, chemicals, water, moisture and weathering tests. The polymer films have also good anti-cracking resistivity against flexing or bending and can be excellent undercoats of vacuum coatings such as vacuum deposition, sputtering and ion plating. The layer constructions can be manufactured with good workability without causing any environmental pollution.
