High-Speed Continuous Curtain Coater for Uniform Coating Thickness with Fully Customizable Options

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.

  • 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

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.
