Side-by-side or coaxial cartridges, from about 25 to 600 milliliters, sized to give ratios such as 1:1, 2:1 or 10:1, fit manual, pneumatic or battery guns. The fixed barrel sizes set the ratio, removing weighing and hand mixing. Before attaching a mixer, operators bleed both sides evenly so neither component leads.
Level the dual cartridge before the mixer goes on, the hardener side's lagging and the first bead will be off.
