- (a) a cartridge containing at least two segregated components of a multi-component curable resin system, which cartridge comprises
- (1) a generally cylindrical, rupturable container containing at least one component of said multi-component curable resin system;
- (2) integral therewith, at one end of and in axial alignment with said generally cylindrical, rupturable container, a mixer having an inlet and an outlet and comprising a liquid permeable, three-dimensional matrix having a plurality of continuous flowpaths therethrough, essentially all of these flowpaths being non-linear;
- and
- (3) means for selectively rupturing said rupturable container at the end thereof adjacent the inlet of said mixer assembly;
- and
- (b) nozzle means at the outlet of said mixer assembly to dispense the curable resin system.
