Air Pockets in 2K Cartridges: How Trapped Air Ruins Mixing Ratios and Precision Dispensing
Air Pockets in 2K Cartridges: How Trapped Air Ruins Mixing Ratios and Precision Dispensing Air pockets trapped within a 2K adhesive cartridge compromise dispensing accuracy, ruin volumetric stoichiometric ratios, and cause uncured or structurally compromised bond lines. When compressed air enters the fluid path of a reactive two-component system, it introduces a compressible buffer that […]
How to Fix Uneven 2K Adhesive Dispensing: Eliminating Lead-Lag and Off-Ratio Output
How to Fix Uneven 2K Adhesive Dispensing: Eliminating Lead-Lag and Off-Ratio Output Uneven two-part adhesive dispensing—manifested as lead-lag flow and off-ratio output—results from pressure imbalances, damaged dispensing pistons, or structural flexing within containers. To fix these issues, operators must inspect piston synchronization, replace compromised static mixers, and upgrade to rigid dual component cartridges featuring solid […]
Why Your Dispensing Needle Keeps Clogging: Gauge Selection Mistakes to Avoid
Why Your Dispensing Needle Keeps Clogging: Gauge Selection Mistakes to Avoid A clogged dispensing needle directly halts automated production lines, alters cycle times, and causes inconsistent bead profiles. In most manufacturing operations, chronic clogging is not caused by defective adhesives, but by gauge selection errors, geometry mismatches, and particle bridge formations. Selecting the right needle […]
Why Your Two-Part Epoxy Isn’t Curing: 7 Mixing and Dispensing Causes
Why Your Two-Part Epoxy Isn’t Curing: 7 Mixing and Dispensing Causes Two-part epoxy is designed to cure only when the resin and hardener are combined in the correct ratio and mixed thoroughly. If you find that your epoxy is not curing, the cause is often not the adhesive chemistry itself but issues in the mixing, […]
Static Mixer Back-Pressure: Why Adhesive Beads Come Out Off-Ratio
A bead comes out lumpy, sticky in one spot, or never cures at all. The easy answer is to blame the adhesive. But before returning a “bad batch” of epoxy or polyurethane, it helps to check the hardware pushing it out. Anyone assembling a dispensing setup should start with a static mixer selection guide, because […]
