Methods, devices and kits for applying structural adhesives

A system for dispensing an adhesive, the system comprising:

• a chamber that holds at least two flexible containment vessels, the at least two flexible containment vessels holding at least a part 1 and a part 2;
• at least two adhesive delivery channels, a first adhesive delivery channel connected to the containment vessel to receive part 1 and a second adhesive delivery channel connected to the containment vessel to receive part 2;
• a motor;
• at least a first variable positive displacement pump wherein the first variable positive displacement pump is actuated by the motor;
• and
• a mixing tip designed to receive part 1 and part 2 from the at least two adhesive delivery channels, mix at least part 1 and part 2 together and dispense the adhesive through a dispensing end,
• wherein when in operation, the at least part 1, part 2, or mixtures thereof are only in contact with the at least two flexible containment vessels, the at least two adhesive delivery channels and the mixing tip, wherein the at least one variable positive displacement pump forces the at least part 1 and at least part 2 respectively through the first adhesive delivery channel and the second adhesive delivery channel to the dispensing end of the mixing tip.
