Abstract (en)
[origin: WO2011023552A1] The invention relates to a method for reinforcing a substrate having a hollow chamber structure or for fastening an insertion in such a substrate, wherein a one or two component foamable and curable preparation based on epoxide resin is introduced into a selected part of the hollow chamber structure that is to be reinforced, and the preparation is cured by heating to a temperature in the range of 20°C to 100°C or greater while foaming, wherein the preparation comprises at least one of the following components: a) at least one epoxide resin prepolymer having reactive epoxide groups, b) at least one organic ammonium carbamate, preferably one that splits off at least 25% of the CO2 bound as carbamate within an hour at a temperature in the range of 20 to 100°C or above; an insertion for mounting in a substrate, the part thereof to be attached within the substrate being at least partially enclosed by such a foamable and curable preparation; an object comprising a substrate having a hollow chamber structure or made thereof, wherein the substrate is reinforced or has an insertion added using said preparation.
