    摘要： 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.

    摘要： A single-component adhesive composition includes: an aqueous acrylic polymer dispersion comprising water and at least one water-dispersed acrylic polymer P; between 0.2 wt.-% and 2.0 wt.-%, preferably between 0.5 wt.-% and 1.5 wt.-%, based on the total composition, of at least one water-dispersed or water-dissolved cross-linker C that can react with carboxylate groups; and between 20 wt.-% and 60 wt.-%, based on the total composition, of at least one filler F with the mean particle size D50 of its primary particles being ≤10 μm, wherein said at least one water-dispersed acrylic polymer P contains free carboxylic acid groups. The composition is highly suitable as adhesive for floor coverings and shows good tack in the wet state and at the same time enables excellent dimensional stability of the bonded floor coverings.

    摘要： A reinforcement element has a carrier having a longitudinal axis and elongate opening extending in the axis direction. The reinforcement element has an insert element having a longitudinal axis constructed to be arranged in the elongate opening. The insert element has first and second portions. The first portions are parallel with a first plane. The insert element longitudinal axis is in this first plane. The second portions are parallel with a second plane. The insert element longitudinal axis is in the second plane. The reinforcement element has a first adhesive which can be arranged on the carrier outer side and on a first group of insert element first portions and to bond the carrier and insert element in the structural element. The reinforcement element has a second adhesive which can be arranged on a second group of insert element first portions and to bond the insert element in the carrier.
