    摘要： A two-component pressurized can having a body, a dome, a valve arranged in the dome, an inwardly curved bottom, an upper chamber and a lower chamber for a first and a second component, which chamber are separated from one another by a separating element, and an opening device which is arranged in the bottom, can be activated from outside and, upon actuation, removes the separation between the chambers for the first and second component, wherein the separating element between the chambers is a piston which is mounted so as to be displaceable in the pressurized can and which has at least one opening closed by a closure element, and the opening device has an opening element which extends through a passage in the bottom and is suitable for separating the closure element from the at least one opening of the piston.

    摘要： A curing agent for epoxy resins has N-benzylethane-1,2-diamine and N,N′-dibenzylethane-1,2-diamine in a weight ratio in the range from 65/35 to 95/5. The curing agent is easy to prepare, thins epoxy resins particularly well, and enables low-emission epoxy resin products that have good workability and a long pot-life, cure reliably and surprisingly fast and can be walked on after a short time, in particular even in cold conditions. Coatings of particularly high mechanical grade, with a high surface quality and a minimal tendency to yellowing, can thus be produced. Epoxy resins of this type are particularly suitable for coating floors.

    摘要： The use of an aldehyde mixture containing 70 to 95 wt % of aldehydes of formula (I) and 5 to 30 wt % of alkylbenzene compounds not corresponding to formula (I) as a blocking agent for amines results in odorless, especially economically blocked amines, which at room temperature are typically liquid and have a surprisingly low viscosity. Such blocked amines are particularly suitable as latent hardeners in isocyanate-group-containing compositions. Single-component moisture-curing polyurethane compositions formulated therewith are surprisingly stable in storage, can be used for low-emission applications without odor problems and do not trigger any problems with plasticizer migration. Surprisingly, said compositions even have advantages over corresponding compositions having latent hardeners based on purified aldehydes of formula (I), in particular with respect to viscosity, storage stability and especially strength.
