Abstract

A foam is disclosed that can be cured by heat having, for example, 10 to 80 vol. % of at least one gas and a compound that can be cured by heat. The foam can include at least one polyurethane polymer and at least one curing agent that can be activated by increased temperature. Foams that can be cured are suitable as flues, sealing compounds, or for the production of coatings, and can be cured by heat for structural adhesive bonds and for lining in vehicle construction.
