Abstract: A structure for a substrate, which includes a layer of fire resistant material, the material including first and second parts mixable together so that the material will cure by an addition reaction in the presence of a metallic catalyst. The first part includes a polydiorganosiloxane polymer having at least two unsaturated groups per molecule. The first part also includes the metallic catalyst, a reinforcing filler, and between 10 and 40%wt. of a vitrifying agent. The second part includes an organohydrogensiloxane crosslinker described by formula R 1 3 Si(OSiR 2 2 ) x (OSiMeH) y OSiR 1 3 , where each R 2 is independently selected from saturated hydrocarbon radicals including from 1 to 10 carbon atoms or aromatic hydrocarbon radicals. Each R 1 is independently selected from hydrogen or R 2 , x is zero or an integer and y is an integer. The organohydrogensiloxane has at least three Si-H bonds per molecule.
