Abstract
Abstract Compositions and processes for forming inorganic resins, including articles of manufacture incorporating these resins are disclosed. The inorganic resins are characterized by their strength, nonflammability, dimensional stability, resistance to organic and inorganic chemicals, to heat and to abrasion and their adaptability to being formed into non-cellular or cellular forms. The resins are formed by reacting a liquid component A containing a mono aluminum or mono magnesium phosphate and a liquid component B containing a magnesium oxide and/or a wollastonite and a dispersing agent. Various fillers may be incorporated and a blowing agent may be added to form a cellular resin.
