Abstract
An improved cartridge structure that both heats the materials contained therein and provides for enhanced structure such that the bypass leaking of the low viscosity heated components is avoided. The cartridge is preferably formed from a rigid material such as reinforced fiberglass tubing. The wall of the cartridge is then wrapped in a flexible heating element or has a heating element cast directly in the wall thereof. The heating elements preferably heat the interior contents and epoxy cartridges to between 150 degrees and 180 degrees Fahrenheit. The wall structure may be of single wall construction with the heaters embedded therein or of a double wall construction such that the heaters are contained between an inner and outer wall. Further the wall construction is preferably formed to withstand the pressures applied when spray applying the epoxy contained therein to prevent the tube wall deformation and resulting blow by leakage.
