Abstract:
Polyurethane foams are made and attached to a substrate having an open cavity, but reacting prepolymer and polyol components in the presence of certain carbamate blowing agents. This process allows for very fast curing, good quality, adherent foamy to be produced on, for example, vehicle parts and assemblies, for acoustical or vibration dampening and for structural reinforcement.
