Roll-to-Roll Curtain Coater for Flexible Films & Paper | High-Speed Continuous Liquid Coating Line – Fully Customizable
Product Overview
A curtain coating machine (also known as a curtain coater) is a precision liquid coating system that creates a continuous, falling "curtain" of coating material through a slotted die head. The substrate passes underneath this curtain on a conveyor, receiving a perfectly uniform, bubble-free coating in a single pass.
This technology is widely used for applying:
  • UV topcoats and sealers on wood (MDF, particleboard, plywood)
  • Scratch-resistant coatings on PVC flooring and laminate
  • Primer or adhesive layers on films, paper, and textiles
  • Functional coatings on metal, glass, and plastic sheets
Key advantages include:
  • Excellent coating uniformity (within ±1-3 microns)
  • High material efficiency (recovery system returns excess coating)
  • No misting or overspray (unlike spray coating)
  • Smooth, orange-peel-free finish
  • High production speed (up to 100 m/min or more)
Our curtain coater is fully customizable for substrate type, coating viscosity, curtain width, line speed, and curing method.

Customization Options
We offer complete customization for the curtain coating machine:
  • Working width: from 300 mm (narrow web) to 2200 mm (large panels)
  • Curtain type: single curtain or double curtain for two-layer application
  • Coating head material: stainless steel (standard) or special alloy for abrasives
  • Conveyor type: PVC belt (for panels) or mesh belt (for air flow drying)
  • Heating system: electric, oil, or steam for coating tank and head
  • Viscosity control: manual or fully automatic with online viscometer
  • Curing tunnel length and lamp type (UV LED, IR, hot air, or hybrid)
  • Integration with existing sanding, printing, or embossing line
  • Cleanroom version for optical films and medical coatings
  • Explosion-proof design for solvent-based coatings
Key Features
  • Uniform coating thickness across full width (±1-3 µm precision)
  • No contact with substrate → zero scratch or streak marks
  • Closed-loop coating circulation with recovery tray (minimal waste)
  • Quick curtain break detection with automatic alarm and shutoff
  • Easy cleaning - slotted die removable without tools (optional quick-release)
  • Variable curtain height adjustment for different substrate thicknesses
  • Viscosity and temperature control for consistent coating quality
  • Low maintenance - no spray nozzles to clog
  • Energy-efficient drying with zone-separated IR or LED lamps
  • User-friendly touchscreen with recipe storage (coating parameters per product)

Frequently Asked Questions
Q: What is the difference between a curtain coater and a roller coater?
A: A curtain coater applies coating without physical contact, eliminating streaks and roller marks. A roller coater uses rotating rollers. We can customize either type or a combination.
Q: Can the curtain coater handle both water-based and UV coatings?
A: Yes, the system is fully customizable for water-based, solvent-based, UV-curable, PU, and epoxy coatings. Different material contact parts are used accordingly.
