  • Patent number: 6776836
    Abstract: The invention relates to adhesives manufacturing. These adhesives are used in household and industry for adhering various materials (concrete, ceramics, different coatings, etc) exploited under temperatures +50° C. to −20° C and under elevated humidity. The adhesive composition represents the product of interaction between potassium silicate aqueous solution (density of 1.3 to 1.37 g/cm3, molar ratio SiO2/K2O of 3.4 to 3.7), anhydrous lithium hydroxide mixed with di- or trihydric alcohol, vollastonite (particle size of 150 &mgr;m and smaller, length to diameter ratio 5-3:1), talc (particle size of 10 to 20 &mgr;m mainly) and inorganic pigment. The adhesive composition is prepared by a given consecutive mixture of components. The adhesive composition has enhanced activity (storage stability) and water resistance. It also has improved strength of adhesion junction while adhering various materials; it is non-toxic and pollution-free.
