  • Patent number: 11781048
    Abstract: A one-component thermosetting epoxy resin adhesive, including a) at least one epoxy resin A of formula (II) wherein substituents R? and R? independently of one another are H or CH3 and index s has value of 0-12, fraction of epoxy resin A being from 20-70 wt.-%, based on total weight of one-component thermosetting epoxy resin adhesive; and b) at least one epoxy novolac EN of formula where R2= or CH2, R1=H or methyl and z=0-7, fraction of epoxy novolac EN being from 1-8 wt.-% based on total weight of one-component thermosetting epoxy resin adhesive; and c) at least one latent hardener B for epoxy resins; and d) at least one accelerator C for epoxy resins; and e) at least at least one toughness improver D, fraction of toughness improver D being from 5-40 wt.-%, based on total weight of one-component thermosetting epoxy resin adhesive.

  • Patent number: 10836881
    Abstract: Pumpable thermally foaming filler compositions based on combinations of a liquid epoxy resin and a polyvinyl chloride resin and/or an acrylic resin powder. The pumpable filler materials provide the advantage that they can be applied as needed using conventional injection equipment and can be expanded to provide foam with good physical strength, high expansion and excellent adhesion on oiled metal substrates. Methods for filling closed spaces with the pumpable thermally foaming filler composition as well as vehicle parts are obtainable with the indicated methods.
