    Abstract: A silane group-containing polymer obtained from reacting (i) an isocyanate group-containing polymer having an NCO content in the range of 0.3 to 4% by weight and a monomeric diisocyanate content of at most 0.3 wt. % obtained from the reaction of at least one monomeric diisocyanate with at least one polyether polyol in a molar NCO/OH ratio of at least 3/1 and subsequent removal of a major part of the unreacted monomeric diisocyanates by means of a suitable separation process, (ii) with at least one amino-, mercapto- or hydroxysilane in a stoichiometric ratio of at least 1 mole of amino-, mercapto- or hydroxysilane per mole equivalent of isocyanate groups.

    Abstract: A composition including: —at least one silane group-containing polymer with a silicon content ranging from 0.6 to 2 wt. %, obtained by reacting at least one isocyanate group-containing polymer and at least one amino-, mercapto-, or hydroxysilane, —at least one liquid epoxy resin, and—at least one polyamine with at least three amine hydrogens which are reactive towards epoxy groups. The composition facilitates adhesives, coatings, or sealing compounds with a good storage stability, a fast curing time, even in the event of moisture or humidity, a surprisingly high degree of strength while having a high degree of elasticity, a high degree of resistance against further tearing, a high degree of resistance in particular against glycol/water mixtures, and a high degree of adhesion to many substrates. When used on metals such as steel or aluminum, the composition protects same against corrosion.

    Abstract: The invention relates to the use of an epoxy resin composition, containing at least one reaction product from the reaction of at least one amine of formula (I) with at least one carbonyl compound of formula (II) and hydrogen, as a cold curing primer or adhesive. Primers or adhesives of this type cure rapidly and trouble-free at ambient temperature, even at cold temperatures such as 10 or 5° C., suffer remarkably little yellowing and are free from toxic phenol compounds such as phenol, tert-butylphenol or nonylphenol. The primer has a particularly low viscosity and is particularly suitable for priming porous mineral substrates.

    Abstract: An amine-functional adduct from the reaction of an amine mixture containing at least one diamine of formula (I) and at least one diamine of formula (II) in a weight ratio ranging from 65/35 to 95/5 with at least one diepoxide in a stoichiometric ratio of at least 1. 2 moles of diamine of the formula (I) to 1 mole equivalent of epoxide groups. The adduct is liquid at room temperature without diluent even in the presence of a small excess of diamine and is surprisingly low in viscosity. In addition, it is particularly cost-effective, as it is available from an amine mixture that is technically easy to produce. The adduct enables low-emission or emission-free epoxy resin coatings with surprisingly good workability at surprisingly fast curing, which have a high hardness and low tendency to yellowing, and which hardly tend to blushing-related defects even in cold and humid conditions.
