摘要： Disclosed is a method for bonding two substrates comprising the sequential steps of
- i) applying a pumpable thermally foaming filler composition on a first substrate S1, and
- ii) placing the second substrate S2 so that the distance between the first substrate S1 and the second substrate S2 at the place of application of the pumpable thermally foaming filler composition is between 2 - 10 mm, and
- iii) heating the first substrate S1 and the second substrate S2 to a temperature above the activation temperature of the foaming agent to foam the pumpable thermally foaming filler composition, wherein between step ii) and step iii) the applied pumpable thermally foaming filler composition is not in contact with the second substrate S2.
The pumpable thermally foaming filler composition comprises at least one rubber, a polyvinylchloride resin and/or acrylic resin powder and a foaming agent. The method of bonding substrates with a thermally expandable composition provides a reduced bond line read through (BLRT) phenomenon.-

摘要： The invention relates to compositions containing at least one solid epoxide resin A, at least one polymer B of formula (I), at least one thixotropic agent C made from a urea derivative and at least one curing agent for epoxide resins D activated by high temperatures. The compositions are particularly suitable for use as adhesives. Low-temperature impact-resistant adhesives can be produced for use in particular as structural adhesives.

摘要： The invention relates to heat-curable epoxy resin compositions containing at least one epoxy resin A with, on average, more than one epoxide group per molecule, at least one curing agent B for epoxy resins, which is activated by an increased temperature, at least one terminally blocked polyurethane prepolymer of formula (I) and at least one epoxide-terminated polyurethane prepolymer of formula (II). Said epoxy resin compositions are particularly suitable for use as one-component, heat-curable adhesives and are characterised by excellent mechanical properties, high glass transition temperatures and high impact resistance.

摘要： Ein System verbundener Karosserieelemente für ein Kraftfahrzeug umfasst ein erstes Karosserieelement (1) und ein zweites Karosserieelement (4). Das erste Karosserieelement hat zumindest einen Kanal (3) an einer Oberfläche, wobei neben dem Kanal eine Schulter (6) ausgebildet ist. Das System umfasst weiterhin einen Klebstoff (8), welcher zumindest teilweise im Kanal und zumindest teilweise auf der Schulter angeordnet ist und das erste Karosserieelement mit dem zweiten Karosserieelement verklebt. Ein direkt an die Schulter anschliessender Anschlussbereich (15) der Oberfläche des ersten Karosserieelementes ist dabei frei von Klebstoff. Ein erster Raum zwischen Schulter und zweitem Karosserieelement und ein zweiter Raum zwischen Anschlussbereich und zweitem Karosserieelement sind gegeneinander offen.
