  • Fireproof inorganic protective coating and the method of its production
    Patent number: 3940516
    Abstract: 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.
