Abstract
Inorganic-organic compositions obtained from a mixture of compounds comprising: PA1 A. from 2-95% by weight of an aqueous alkali metal silicate solution; and containing about 20-70% by weight of said alkali metal silicate and, PA1 B. from 5-98% by weight of an organic nonionic hydrophilic polyisocyanate. A water-binding material such as hydraulic cement may be included in the reaction mixture. The products of the invention may be used in many forms including both porous and non-porous products as surface coatings having good adhesion and resistance to abrasion, as a mortar, and as a foam concrete for making molded products particularly in construction engineering and civil engineering as for building walls, igloos, road building and the like. Products are especially useful as lightweight thermal insulating materials with excellent mechanical properties and fire-resistance.
