Overview
The Erichsen #509MC Coating Applicator System is a precision-engineered, microprocessor-controlled laboratory instrument designed for standardized wet-film application and controlled drying time evaluation of liquid coatings, inks, adhesives, and functional dispersions. Based on the principle of reverse-roll coating with adjustable gap geometry and programmable linear draw-down speed, the system ensures high reproducibility in film thickness generation across diverse substrate types—including metal panels, glass slides, plastic films, and paper. Its dual configuration (#509MC-I and #509MC-III) supports both standalone film deposition and integrated drying kinetics monitoring under ambient or conditioned environments, making it essential for R&D laboratories, quality control departments, and regulatory-compliant formulation development in paint, printing, automotive OEM, and packaging industries.
Key Features
- Microprocessor-controlled linear drive mechanism with 15 selectable draw-down speeds (2.5–80 mm/s), calibrated to ±0.3% full scale
- Modular architecture: base unit houses precision-guided carriage, motorized applicator bar assembly, and removable paint collection trough
- Dedicated control box with intuitive membrane keypad, real-time speed/duration display, and non-volatile parameter memory
- Interchangeable applicator bars (not included) enabling precise wet-film thickness control via defined gap geometry (e.g., 25 µm–500 µm)
- Robust aluminum alloy frame with vibration-damped feet; designed for long-term stability on standard lab benches
- Universal power input (115/230 V AC, 50/60 Hz) with internal auto-sensing circuitry and CE-compliant safety isolation
Sample Compatibility & Compliance
The #509MC accommodates substrates up to 400 mm in width and 10 mm in thickness, including ISO-standardized steel, aluminum, and glass test panels (e.g., ASTM D1005, ISO 2808, EN 23272). It supports Newtonian and moderately shear-thinning fluids with viscosity ranges from 10 mPa·s to 5,000 mPa·s (measured at 25 °C). All operational parameters—speed, dwell time, and (in #509MC-III) drying interval—are logged with timestamp and user ID, supporting GLP/GMP traceability requirements. The system complies with IEC 61000-6-2 (EMC immunity) and IEC 61000-6-4 (EMC emission) standards, and its mechanical design conforms to ISO 12782-2 for coating applicator performance verification.
Software & Data Management
While the #509MC operates as a stand-alone hardware platform without embedded PC software, its control box provides full audit trail capability: all executed runs are stored internally (up to 255 entries) with date/time stamp, selected speed, and duration. Optional RS-232 serial output (available via accessory interface module) enables integration with external LIMS or ELN systems for automated data export in CSV format. Parameter settings are protected by password-locked configuration mode, satisfying FDA 21 CFR Part 11 requirements for electronic records when paired with validated third-party data acquisition software. Calibration certificates traceable to DAkkS-accredited national standards are available upon request.
Applications
- Wet-film thickness validation per ASTM D823 and ISO 2808 Annex A
- Drying time assessment (tack-free, dust-free, through-dry) per ISO 9117-1 and ASTM D1640
- Coating uniformity screening during raw material qualification
- Formulation optimization studies involving rheology–drying correlation
- QC release testing for industrial coatings, UV-curable inks, and water-based adhesives
- Preparation of test specimens for cross-hatch adhesion (ASTM D3359), pencil hardness (ASTM D3363), and gloss measurement (ISO 2813)
FAQ
What is the difference between #509MC-I and #509MC-III?
The #509MC-I is a microprocessor-controlled draw-down applicator only. The #509MC-III integrates an additional drying time recording function with programmable intervals (0.5–108 min/cm) and visual/audible endpoint indication.
Is the applicator bar included with the system?
No. Applicator bars (e.g., Erichsen 0167.03.xx series) are ordered separately based on required wet-film thickness and substrate compatibility.
Can the #509MC be used with volatile organic solvents?
Yes, provided appropriate ventilation and explosion-proof lab infrastructure are in place; the system contains no internal ignition sources and uses Class II insulation.
Does the unit support custom speed profiles or ramped acceleration?
No. Speed selection is discrete and stepwise; continuous ramping or multi-segment profiles require external motion controllers.
What maintenance is required for long-term accuracy?
Annual verification of carriage linearity and speed calibration using certified optical encoder reference; routine cleaning of guide rails and applicator bar contact surfaces with isopropyl alcohol.
