Overview
Greenson MEK Rubbing Pads are precision-engineered consumable test media designed exclusively for use with DJH MEK Friction Test Machines—industrial-grade instruments used to evaluate the resistance of coated, printed, or laminated surfaces to organic solvent abrasion. These pads are manufactured to strict dimensional and material consistency standards, ensuring repeatable contact geometry, uniform solvent retention, and controlled mechanical interaction during standardized rubbing cycles. Unlike generic cotton swabs or laboratory wipes, Greenson pads are fabricated from high-purity, low-lint, non-bleached cotton fiber with calibrated density and compressibility—critical parameters that directly influence solvent delivery rate, friction coefficient, and wear path reproducibility in ASTM D5402, ISO 11340, and related solvent rub resistance protocols.
Key Features
- Consistent pad dimensions (standardized thickness, diameter, and edge profile) to maintain identical contact area and pressure distribution across test runs
- Controlled absorbency and solvent release kinetics optimized for methyl ethyl ketone (MEK) and other halogen-free solvents used in industrial coating validation
- Low particulate generation and zero extractables—certified free of silicone, plasticizers, and surfactants that could interfere with surface chemistry or optical clarity assessment
- Batch-certified traceability with lot-specific documentation supporting GLP-compliant test records and audit readiness
- Compatible with automated DJH MEK test platforms featuring programmable stroke length, reciprocating speed, and load control
Sample Compatibility & Compliance
Greenson MEK Rubbing Pads are validated for use on a broad spectrum of substrate types—including automotive clearcoats, aerospace polyurethane topcoats, packaging film laminations, and printed electronics substrates. Their neutral composition ensures no unintended chemical interaction with sensitive coatings such as UV-cured acrylates or waterborne epoxies. The pads conform to requirements outlined in ASTM D5402 (“Standard Test Method for Resistance of Organic Coatings to the Effect of Solvent Rub”) and support full compliance with ISO 11340 (“Paints and Varnishes — Determination of Resistance to Solvent Rubbing”). When used within certified DJH instrument workflows, test data generated with Greenson pads meet documentation integrity criteria under FDA 21 CFR Part 11 for electronic records and signatures, provided the host system implements appropriate audit trail and user access controls.
Software & Data Management
While Greenson pads themselves are passive consumables, their performance is intrinsically linked to the operational fidelity of DJH MEK test systems. Modern DJH platforms integrate with proprietary software suites that log real-time parameters—including cycle count, stroke frequency, applied load, and solvent volume dispensed per cycle. Greenson pads enable stable baseline performance across these variables, minimizing inter-pad variability that could otherwise mask true coating degradation trends. All pad lots include QR-coded labels linking to digital certificates of conformance, including fiber purity assay reports and solvent absorption rate profiles. This integration supports structured data capture in LIMS environments and facilitates automated reporting for internal quality reviews or regulatory submissions.
Applications
- Quality assurance of OEM automotive refinish coatings during production line release testing
- Accelerated durability screening of architectural fluoropolymer façade systems exposed to urban solvent pollution
- Validation of ink adhesion on flexible food packaging films subjected to ethanol-based cleaning protocols
- R&D benchmarking of novel anti-graffiti coatings using standardized MEK rub cycles
- Supplier qualification audits requiring third-party verifiable test media provenance and consistency
FAQ
Are Greenson MEK Rubbing Pads supplied sterile or individually wrapped?
No—these are industrial-grade test consumables intended for controlled lab environments; they are packaged in sealed, low-particulate polyethylene bags with desiccant and do not undergo terminal sterilization.
Can these pads be reused across multiple test cycles?
No—each pad is designated for single-use per ASTM D5402 Section 7.3 to prevent carryover contamination and ensure consistent solvent saturation and surface wear characteristics.
Do Greenson pads meet RoHS or REACH substance restrictions?
Yes—certification documentation confirms absence of SVHC substances listed under REACH Annex XIV and full compliance with RoHS Directive 2011/65/EU for restricted heavy metals and flame retardants.
Is there a shelf-life specification for unopened pad packages?
Yes—recommended storage is at 15–25°C and ≤60% RH; unopened packages retain full performance specifications for 36 months from date of manufacture, as verified by accelerated aging studies.
