  • LOW-EMISSION HARDENER FOR EPOXY RESINS
    Publication number: 20140107313
    Abstract: The present invention concerns a low-odor, low-viscosity hardener for epoxy resins comprising the amine of formula (I), as well as a method for thinning of hardeners for epoxy resins by adding the amine of formula (I). These hardeners harden with epoxy resins quickly and without blushing to form films of high hardness and little brittleness, even without non-incorporable thinners such as benzyl alcohol. They are especially suitable for low-emission coatings.

  • HEAT-CURING SEALING COMPOUND COMPOSITIONS HAVING FAST SKIN FORMATION AND GOOD STORAGE STABILITY
    Publication number: 20130280526
    Abstract: The invention relates to heat-curing sealing compound compositions comprising at least epoxy resin, a heat-activatable hardening agent or accelerators (B) for epoxy resins, isocyanate group-containing polyurethane polymer (PUP) and a special polyaldimine. Said single-component sealing compound compositions are characterized by a good skin formation time and extraordinarily good storage stability and low blistering. Due to these properties, said sealing compound compositions are optimally suitable for use as sealants in autobody work because they can be excellently coated with a KTL paint.

  • HEAT-CURING SEALANT COMPOSITIONS HAVING FAST SKIN FORMATION AND HIGH TENSILE STRENGTH
    Publication number: 20130280536
    Abstract: The present invention relates to heat-curing sealant compositions including at least epoxy resin, dicyanodiamide or an amine complex of a Lewis acid, polyurethane polymer (PUP) containing isocyanate groups and polyaldimine. These single component sealant compositions are characterized by a rapid skin formation and high tensile strength. Because of the short skin formation time, said compositions are optimally suitable for use as sealants in autobody work because they can be excellently layered on top of same.

  • Process for removing carbonaceous deposits on surfaces of catalysts and plant parts
    Patent number: 8349090
    Abstract: A process for removing carbonaceous deposits on surfaces of catalysts and plant parts by treating the deposits with a superheated stream of steam admixed at least temporarily with an oxygenous gas is provided, which involves, in each case monitoring the offgas CO2 content after condensation of the steam, at a temperature of at least 300° C.: (a) treating the carbonaceous deposits with superheated steam at a temperature of at least 300° C. until the CO2 content of the offgas has exceeded a maximum; (b) then, with further supply of superheated steam, commencing oxygen supply, the amount of oxygen supplied being adjusted such that the CO2 content in the offgas decreases further until it has fallen to a value of <1% by volume; and then (c) ending the supply of superheated steam and passing an oxygenous gas over remaining amounts of carbonaceous deposits until the deposits have been virtually removed.
