Overview
The Labthink CY-6S Pressure-Sensitive Adhesive Tape Holding Power Tester is an engineered solution for quantifying the resistance of pressure-sensitive adhesive (PSA) materials to shear-induced debonding under constant load and controlled environmental conditions. Based on the principle of vertical static shear testing—where a standardized test specimen is affixed to a stainless steel test plate, loaded with a precisely calibrated mass, and suspended vertically—the instrument measures either the displacement of the specimen after a defined time interval or the elapsed time until complete detachment. This methodology directly reflects real-world performance of PSAs in applications where long-term shear stress is encountered, such as medical transdermal patches, industrial labeling, protective films, and electronic component masking tapes. The system adheres strictly to internationally recognized test protocols, including GB/T 4851 (China), ASTM D3654 (USA), and JIS Z0237 (Japan), ensuring data comparability across global R&D, QC, and regulatory submission workflows.
Key Features
- Six independent test stations enable parallel evaluation of multiple specimens—significantly improving throughput for batch validation and comparative studies.
- Microprocessor-controlled timing system with automatic start/stop logic and digital locking function ensures repeatability and eliminates operator-dependent timing errors.
- Standardized test hardware—including 60 mm × 40 mm × 1.5 mm stainless steel test plates, 1000 g ± 10 g load masses (inclusive of loading plate), and a 2000 g ± 50 g standard roller—guarantees compliance with dimensional and mechanical tolerances specified in GB/T 4851 and ASTM D3654.
- Intuitive PVC membrane keypad interface paired with a high-contrast LCD display allows rapid setup, real-time monitoring, and immediate access to elapsed time and status indicators without external software dependency.
- Robust structural design features a rigid aluminum-alloy frame and vibration-dampened base, minimizing external perturbation effects during extended-duration tests (up to 9999 hours with optional firmware).
- Universal power input (220 VAC 50 Hz / 120 VAC 60 Hz) supports deployment in both domestic and international laboratory environments without voltage conversion hardware.
Sample Compatibility & Compliance
The CY-6S is validated for use with a broad spectrum of pressure-sensitive adhesive substrates, including acrylic, rubber-based, silicone, and hydrogel formulations. It accommodates common commercial formats: single-layer tapes, laminated medical patches, printable label stocks, PET/PE protective films, and solvent-free transfer adhesives. All test configurations conform to the specimen preparation, surface conditioning, and dwell time requirements outlined in GB/T 4851–2018, ASTM D3654–22, and JIS Z0237:2021. For pharmaceutical applications, the system supports documentation practices aligned with ICH Q5E stability guidance and USP Adhesive Testing of Transdermal Delivery Systems. While not inherently 21 CFR Part 11 compliant, audit trails and raw data export (via optional RS-232 or USB interface) can be integrated into validated LIMS or ELN platforms meeting GLP/GMP data integrity requirements.
Software & Data Management
The CY-6S operates as a standalone hardware platform with embedded firmware; no proprietary PC software is required for basic operation. However, optional serial (RS-232) or USB connectivity enables integration with laboratory information management systems (LIMS) or custom data acquisition scripts. Time-stamped test logs—including start time, detachment time (or displacement at fixed intervals), station ID, and operator code—can be exported in CSV format for traceability and statistical process control (SPC) analysis. Firmware updates are delivered via secure download and verified checksums to maintain configuration integrity—a critical consideration for regulated environments requiring documented change control procedures.
Applications
- Quality control of roll-to-roll manufactured PSA tapes in packaging, electronics, and automotive assembly lines.
- Stability assessment of transdermal drug delivery patches across accelerated and real-time aging conditions per ICH Q1 guidelines.
- Comparative evaluation of adhesive formulation variants during R&D, including cross-linker concentration, polymer molecular weight, and tackifier selection.
- Validation of cleaning or removal efficacy for temporary protective films used in precision optics and semiconductor wafer handling.
- Regulatory submission support for FDA 510(k), CE Marking (MDR Annex I), and NMPA Class II/III medical device dossiers requiring adhesion performance data.
FAQ
What standards does the CY-6S comply with?
The instrument meets the mechanical and procedural requirements of GB/T 4851–2018, ASTM D3654–22, and JIS Z0237:2021 for holding power testing of pressure-sensitive adhesives.
Can the CY-6S be used for medical device adhesive validation?
Yes—its standardized loading geometry, temperature-stable construction, and repeatable timing make it suitable for ISO 10993-5 cytotoxicity pre-screening and USP adhesion assessments when operated within controlled ambient conditions.
Is calibration certification included with purchase?
Labthink provides factory calibration documentation traceable to national metrology institutes; users are advised to perform periodic verification using certified mass standards and stopwatch calibration tools per ISO/IEC 17025 internal audit protocols.
How is test data stored and retrieved?
All test records are retained in non-volatile memory and displayed on the LCD; optional communication interfaces allow direct export to external databases or spreadsheets for long-term archival and trend analysis.
Does the system support elevated temperature testing?
The base CY-6S is designed for ambient-temperature operation only; integration with environmental chambers (e.g., 25°C–40°C) requires external enclosure and careful thermal isolation to prevent drift in timing electronics and mechanical creep effects.
