Abstract
A foam mixer-applicator for mixing a two-part foamable composition includes a mixing head having a mixing chamber for impingement mixing of the two component parts of the foamable composition, which are supplied to the mixing chamber in a pre-pressurized state. The mixing head is sealingly connected to a dispensing head having a foaming chamber of a substantially greater capacity than the mixing chamber and an outlet port for discharging the foam composition after foaming and acquiring a higher, yet flowable viscosity. A pneumatic plunger system pushes the foamed composition through an outlet port of the dispensing housing onto a substrate.
