Estimating the term…
An inorganic fireproof protective coating composition consisting of 5 to 15 percent by weight of a powdered silicate-oxide sinter or alloy, 15 to 35 percent by weight of an anhydrous powdered alumosilicate substance, and 50 to 80 percent of the acid phosphates of aluminum, chromium, magnesium or calcium, or mixtures thereof. All three ingredients of the coating form a suspensoid upon mixing and thereafter they are subjected to self-hardening at room temperature. The hardening process may be accelerated by heating up to 150.degree.C. The coating is designed for protection of products made of readily inflammable materials, particularly of wood and of wood-like materials, against destruction by fire or glow.
A fireproof inorganic protective air hardenable coating mixture comprising (A) 5 to 15 percent by weight of a silicate oxide sinter or alloy comprising 50 to 65 percent by weight of Fe.sub.2 O.sub.3 plus FeO in any weight proportion, 3 to 8 percent of CuO plus CuO.sub.2 in any weight proportion, 2 to 7 percent by weight of CaO, 20 to 30 percent by weight of SiO.sub.2, and 0 to 10 percent of other oxides selected from the group consisting of Al.sub.2 O.sub.3, TiO.sub.2, NiO, CoO, MgO, Na.sub.2 O and K.sub.2 O in any weight proportion;
A method of producing a coated substrate comprising grinding to a grain size smaller than 0.5 mm (A) 5 to 15 percent by weight of a silicate oxide sinter or alloy comprising 50 to 65 percent by weight of Fe.sub.2 O.sub.3 plus FeO in any weight proportion, 3 to 8 percent of CuO plus CuO.sub.2 in any weight proportion, 2 to 7 percent by weight of CaO, 20 to 30 percent by weight of SiO.sub.2, and 0 to 10 percent of other oxides selected from the group consisting of Al.sub.2 O.sub.3, TiO, NiO, CoO, MgO, Na.sub.2 O and K.sub.2 O in any weight proportion and (B) 15 to 35 percent by weight of an anhydrous aluminosilicate substance in the natural state or which has been sintered at a temperature above 1,000.degree.C, and said substance comprising 40 to 75 percent by weight of SiO.sub.2, 10 to 45 percent by weight of Al.sub.2 O.sub.3, 0 to 15 percent by weight of Fe.sub.2 O.sub.3 plus FeO in any weight proportion, and 0 to 10 percent by weight of other oxides selected from the group consisting of TiO.sub.2, CaO, MgO, Na.sub.2 O and K.sub.2 O in any weight proportion;
