Abstract
Quantities of two low viscosity liquid components are provided in separated portions of a flexible bag or package. Separable attachment of package walls between the liquid components is broken, and the liquids are mixed together within the package by manipulating its flexible walls. The flexible package containing the mixed components is inserted into a barrel of a dispenser, and a portion of the package adjacent the front end of the barrel is removed. A nozzle is attached to the front end of the barrel, and a driving mechanism is manually activating to drive a plunger along the barrel toward the nozzle to compress the flexible package and thereby dispense the material in the package through the nozzle. When mixed the liquid components first form a higher viscosity, non-sag, non-flowing, thixotropic composition for a period of time during which dispensing from the dispenser can occur, and thereafter form a resiliently flexible solid sealing composition.
