EcoDose 2K — Two-Component Electronic Dosing

Precise 2K mixing. Every shot. Every time.

An electronic dosing system for two-component paint processes — delivering precisely consistent mixing ratios across a wide viscosity range, with automatic colour change capability, independent flushing circuits, and real-time pot life monitoring.

Why this product

Manual 2K mixing is consistently inconsistent.

Manual mixing of two-component paints — catalyst ratio measured by eye, bucket, or rough volume — produces ratio variation that shows up as soft spots, incomplete cure, early delamination, and corrosion in service. Every off-ratio mix is a potential warranty claim. The EcoDose 2K eliminates human ratio error entirely.

  • Electronic dosing delivers consistent catalyst ratios across the full production shift — no operator variation
  • Flow rate range 40–4,000 cc/min covers low-flow touch-up to full production volume
  • Coriolis flowmeter option: mass-flow measurement independent of viscosity or temperature variation
  • Gear flowmeter option: volume-controlled precision dosing at lower system cost
  • Real-time pot life monitoring with catalyst ratio tracking and process alerts
  • Independent flushing circuits for each component — no premixing chamber, minimal waste at colour change

How it works

Measure, ratio, flush

01

Component supply and metering

Base paint (Component A) and catalyst/hardener (Component B) are supplied from separate EcoPump packages to the EcoDose 2K dosing unit. The Coriolis or gear flowmeters measure the exact volume or mass of each component independently — in real time, continuously.
