Europlasma CD2400 Roll-to-Roll Halogen-Free & Fluorine-Free Plasma Coating System

Overview

The Europlasma CD2400 is a vacuum-based, roll-to-roll (R2R) plasma coating system engineered for industrial-scale functional surface modification under controlled low-pressure environments. Unlike atmospheric plasma or spray-coating methods, the CD2400 utilizes low-temperature, non-thermal plasma to drive surface polymerization and atomic-layer-like deposition—enabling conformal, pinhole-free nanoscale coatings on flexible substrates without thermal degradation or bulk property alteration. The system operates via capacitively coupled RF plasma (13.56 MHz), generating uniform plasma density across the entire web width (2400 mm), with precise control over ion energy, radical flux, and monomer incorporation. Its halogen-free and fluorine-free process architecture aligns with EU RoHS 2011/65/EU, REACH Annex XIV restrictions, and IPC-4552B requirements for electronics-grade surface treatments—making it suitable for regulated sectors including medical device manufacturing, battery separator functionalization, and consumer electronics waterproofing.

Key Features

• Roll-to-roll architecture supporting continuous web processing at speeds up to 10 m/min (configurable per substrate and coating specification)
• Dual-process capability: compatible with both Nanofics® proprietary precursors (e.g., Nanofics 10 for halogen-free hydrophobic layers) and PlasmaGuard® certified halogen-free, fluorine-free chemistries
• Integrated 5 kW RF generator with impedance-matching network for stable plasma ignition and long-term power reproducibility (>99.2% stability over 8-hour runs)
• Aluminum vacuum chamber (2400 mm × Ø1000 mm) with ISO-KF 63/100 flanges, base pressure <5 × 10⁻³ mbar, and leak rate <1 × 10⁻⁹ mbar·L/s He
• Full automation via PLC-based HMI with recipe management, real-time gas flow monitoring (MFC-controlled O₂/Ar/N₂), and integrated safety interlocks compliant with EN 60204-1 and IEC 61508 SIL2
• Modular design allows integration of in-line metrology options—including optical emission spectroscopy (OES) for plasma diagnostics and ellipsometry-compatible quartz crystal microbalances (QCM) for real-time deposition rate tracking

Sample Compatibility & Compliance

The CD2400 accommodates a broad range of flexible, porous, and temperature-sensitive substrates—including PET, PI, PP, nonwovens, electrospun nanofiber mats, lithium-ion battery separators (e.g., PE/PP trilayer films), and medical-grade silicone tubing. Its low-temperature plasma (115° (hydrophobic) or <10° (superhydrophilic), depending on precursor selection and plasma parameters. All process documentation supports GLP-compliant audit trails, and software logs meet FDA 21 CFR Part 11 requirements for electronic records and signatures when paired with optional validation packages.

Software & Data Management

The system runs on Europlasma’s proprietary CoatingControl™ v4.2 platform—a Windows-based SCADA interface with role-based access control (operator, engineer, QA), automated calibration logging, and CSV/PDF report export. It features synchronized timestamping across all sensors (pressure, RF forward/reflected power, gas flows, temperature), enabling full traceability for quality investigations. Historical data is stored locally with optional cloud backup (AWS IoT Core integration available). Audit trail functionality includes user login/logout events, parameter changes, alarm acknowledgments, and batch-specific metadata—fully aligned with ISO 13485:2016 clause 7.5.10 and ICH Q9 risk-based documentation principles.

Applications

• Consumer electronics: Conformal waterproofing of wearables (TWS earbuds, smart bands) achieving IPX7/IPX8 ratings without compromising signal transmission or tactile feedback
• Lithium-ion battery manufacturing: Hydrophilic surface activation of ceramic-coated separators to enhance electrolyte wettability and reduce interfacial resistance
• Medical devices: Plasma-deposited anti-thrombogenic layers on polyurethane catheters and antimicrobial coatings on melt-blown mask media using silver-ion-doped PlasmaGuard® formulations
• Outdoor technical textiles: Durable water repellency (DWR) on nylon ripstop fabrics without PFAS, validated per AATCC TM193-2021
• Flexible printed electronics: Surface energy tuning of PI substrates prior to inkjet-printed Ag nanoparticle deposition, improving adhesion and line resolution

FAQ

What vacuum level does the CD2400 achieve, and how is it maintained during continuous operation?
The system reaches a base pressure of ≤5 × 10⁻³ mbar using a dual-stage rotary vane pump and optional turbomolecular pumping package. During R2R processing, dynamic pressure is actively stabilized via closed-loop throttle valve control synchronized with web speed and gas inflow.
Can the CD2400 deposit both hydrophobic and hydrophilic coatings on the same substrate in one pass?
Yes—via sequential zone processing: upstream zones activate surfaces with O₂ plasma (increasing surface energy), while downstream zones apply Nanofics 10 or PlasmaGuard® precursors under controlled Ar/O₂ mixtures to tune wettability gradients.
Is IQ/OQ/PQ validation support available for pharmaceutical or medical device production environments?
Europlasma provides full GMP-aligned validation documentation kits, including URS templates, FAT/SAT protocols, and 21 CFR Part 11-compliant software qualification reports—delivered by certified third-party validation partners upon request.
How does the system handle edge effects on wide-web substrates?
The CD2400 employs field-shaping electrodes and symmetric gas injection manifolds to minimize radial plasma non-uniformity; uniformity across 2400 mm width is verified via calibrated Langmuir probe mapping and confirmed to ±3.2% standard deviation in deposition rate.
Are replacement consumables and precursor chemicals supplied directly by Europlasma or through authorized distributors?
All Nanofics® and PlasmaGuard® precursors are manufactured and quality-controlled at Europlasma’s ISO 9001-certified facility in Herentals, Belgium; supply chain includes cold-chain logistics and lot-specific CoA/COC documentation for regulatory submissions.
