  • Patent number: 11279796
    Abstract: A heat-curing epoxy resin compositions which can in particular be used as bodyshell adhesives for motor vehicle construction. The heat-curing epoxy resin compositions contain a curing agent which can be activated through elevated temperature and has a first component K1 containing at least one epoxy resin and a second component K2 containing at least one tertiary amine and also a primary amine. These compositions, after short-term heating of 30 to 120 seconds at a temperature of 90° C. to 130° C., exhibit sufficient strength and adhesion to withstand transport-induced mechanical strains.

  • Patent number: 11208580
    Abstract: A single-component thermosetting epoxy resin adhesives, including: a) at least one epoxy resin having, on average, more than one epoxy group per molecule; b) at least one latent hardener for epoxy resins; and c) 2-7 wt % aerogel particles, relative to the total weight of the single-component thermosetting epoxy resin adhesive, wherein the epoxy resin adhesive has a viscosity of 1000-4000 Pas, in particular 1000-3500 Pas, at 25° C., wherein the viscosity is oscillographically determined by means of a rheometer having a heatable plate (MCR 301, AntonPaar) (gap 1000 ?m, measurement plate diameter: 25 mm (plate/plate), deformation 0.01 at 5 Hz, temperature: 25° C.). The epoxy resin adhesives are characterized in that they can be easily applied in the temperature range from 40° C. to 70° C. and are scouring-resistant, even at higher temperatures.

  • Patent number: 9512341
    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.

  • 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.
