Real named materials TIMs, epoxies, silicones, urethanes, acrylics — same electronics tie as EFR. Sellable feature: 'base purge' conserves material during changeovers without replacing static/dynamic mixers, which matters on a line running multiple two-component recipes per shift. Manuals 3A8565EN-G, 345203EN-C.

Skipping base purge on a line running multiple two-component recipes per shift forces a static/dynamic mixer swap at every ratio changeover — the material and downtime cost base purge is built to remove.
A line running several two-component TIM or epoxy recipes per shift loses time and material every time a mixer has to be swapped for a ratio change. EVR's base purge is the feature that removes that step — the real reason to spec EVR over a fixed-ratio EFR when the electronics line runs more than one adhesive chemistry.

FAQ
Is Electric Variable Ratio Meter-Mix Proportioner (EVR) used in Electronics Manufacturing?
Real named materials TIMs, epoxies, silicones, urethanes, acrylics — same electronics tie as EFR. Sellable feature: 'base purge' conserves material during changeovers without replacing static/dynamic mixers, which matters on a line running multiple two-component recipes per shift. Manuals 3A8565EN-G, 345203EN-C. This is moderate evidence.
