The invention relates to a binding agent composition, in particular an adhesive, containing at least one epoxy compound or at least one amino compound comprising at least two amino groups, or at least one hydroxy compound comprising at least two OH groups, or at least one mercapto compound comprising at least two mercapto groups, or at least one isocyanate comprising at least two NCO groups and a compound with chelating properties. The invention also relates to a method for producing binding agent compounds of this type and to the use of the same.

Binding agent component for surface coating agents with improved adhesive properties

The invention relates to alkaline cleaners containing two components A and B, component A being a strongly alkaline solution comprising mostly alkali metal hydroxides and employed in an excess, component B being a concentrate comprising an aqueous silicic acid dispersion containing anionic, nonionic or amphoteric tensides, builder substances, stabilizers and optionally inorganic mineral acids, complexing agents and/or preservatives. Component B contains, as an active ingredient, adjusted to a pH in the range of from 1 to 11, a silicic acid dispersion obtained in situ by treating an alkali metal silicate solution with a mineral acid or a gas reacting acidically in aqueous solution. The dispersions also contain stabilizers, tensides and builder substances. If desired, additional agents conventionally contained in cleaning concentrates may also be added. The invention also relates to processes for preparing such cleaners by treating an alkali metal silicate solution with a mineral acid or a gas reacting acidically in aqueous solution and adding tensides, stabilizers and builder substances thereto.
