60557-3382 Abstract of the Disclosure An extrudable epoxy resin and curing agent that poly- merize when mixed are separated by an extrudable barrier layer disposed between and in contacting relationship with the epoxy resin and curing agent. The material of the barrier layer is insoluble in the epoxy resin and curing agent while being disper- sible in a mixture of them. The barrier layer material is select- ed from hydrogenated rosin ester, terpene phenolic resin, alpha- pinene resin and polybutene. The epoxy resin, curing agent and barrier layer have sufficiently similar rheologies at the tempera- ture at which they are to be extruded from their container to ensure against intermixing until after they emerge from the con- tainer outlet.
