Overview
The Labthink CZY-6S Adhesion Holding Power Tester is a precision-engineered instrument designed to quantify the creep resistance—or holding power—of pressure-sensitive adhesives under constant static load. It operates on the principle of vertical shear creep testing: a standardized test specimen is affixed to a stainless-steel test plate, which is then vertically suspended in the tester’s frame; a calibrated weight is applied via a loading plate, inducing sustained shear stress at the adhesive–substrate interface. The instrument measures either the displacement of the specimen after a defined time interval or the total time elapsed until complete debonding occurs. This method directly reflects real-world performance of adhesive products subjected to gravitational or mechanical hold-down forces over extended durations—critical for applications ranging from medical transdermal patches to industrial protective films.
Key Features
- Six independent test stations enable parallel evaluation of multiple specimens, improving throughput and statistical robustness without cross-interference.
- Microprocessor-based control system with PVC membrane keypad and LCD display ensures intuitive operation, real-time monitoring, and reliable data capture.
- Precision-machined test plates (60 mm × 40 mm × 1.5 mm) and loading components conform strictly to dimensional tolerances specified in GB/T 4851, ASTM D3654, and JIS Z0237.
- Standardized 2000 g ± 50 g roller for consistent sample preparation (e.g., lamination uniformity), and 1000 g ± 10 g applied load (inclusive of loading plate mass) ensure metrological traceability.
- Programmable timing range up to 99 hours as standard; extended 0–9999-hour mode available for long-term stability studies under GLP-compliant conditions.
- Sturdy aluminum-alloy frame and vibration-damped base minimize environmental influence on displacement measurement accuracy.
Sample Compatibility & Compliance
The CZY-6S supports a broad spectrum of pressure-sensitive adhesive formats, including but not limited to: acrylic- and rubber-based tapes (e.g., 3M™ VHB™, Scotch® series), medical hydrocolloid and silicone gel patches, self-adhesive labels, PET/PE protective films, and pharmaceutical transdermal delivery systems. All test configurations comply with internationally recognized standards for holding power assessment: GB/T 4851–2014 (China), ASTM D3654–18 (U.S.), and JIS Z0237:2020 (Japan). These protocols define specimen conditioning (23 °C ± 2 °C, 50% RH ± 5%), application pressure, dwell time prior to loading, and pass/fail criteria—enabling direct comparability across global R&D, QC, and regulatory submissions.
Software & Data Management
While the CZY-6S operates as a standalone hardware platform with embedded firmware, its test logs—including start time, elapsed duration, displacement (if measured manually), and station-specific pass/fail status—are timestamped and displayed in real time on the LCD screen. For laboratories requiring electronic records compliant with FDA 21 CFR Part 11, Labthink offers optional PC-based data logging software with audit trail functionality, user access controls, and export to CSV or PDF formats. All raw data entries are immutable post-recording, supporting GMP/GLP documentation integrity during internal audits or regulatory inspections.
Applications
- Quality Control: Routine verification of batch-to-batch consistency in adhesive formulation, coating thickness, and substrate priming processes.
- Regulatory Testing: Supporting submissions to NMPA (China), FDA (U.S.), and PMDA (Japan) for medical device adhesives, where holding power correlates with skin contact safety and efficacy.
- R&D Screening: Comparative evaluation of novel adhesive chemistries (e.g., bio-based acrylics, thermally reversible tackifiers) under accelerated aging or humidity-cycled conditions.
- Failure Analysis: Diagnosing root causes of premature delamination in laminated packaging structures or wearable sensor assemblies.
- Standards Calibration Support: Serving as a reference system for validating secondary test fixtures or custom-built creep rigs within accredited labs.
FAQ
What standards does the CZY-6S fully support out-of-the-box?
The instrument meets all mechanical and procedural requirements of GB/T 4851–2014, ASTM D3654–18, and JIS Z0237:2020—including test plate geometry, load mass tolerance, vertical alignment, and environmental conditioning guidelines.
Can the CZY-6S be integrated into a LIMS or ELN environment?
Yes—via optional RS-232 or USB-to-serial interface, paired with Labthink’s certified data acquisition software that generates ALCOA+ compliant records (Attributable, Legible, Contemporaneous, Original, Accurate).
Is the 1000 g load inclusive of the loading plate mass?
Yes—the total applied force corresponds to 1000 g ± 10 g, which includes the mass of the stainless-steel loading plate; no additional calibration weights are required.
How is specimen alignment verified before testing?
Each station features engraved centering guides and spring-loaded clamping arms to ensure repeatable 10-mm overhang beyond the test plate edge, per ASTM D3654 Section 7.2.
Does Labthink provide installation qualification (IQ) or operational qualification (OQ) documentation?
Upon request, Labthink supplies vendor-verified IQ/OQ protocols aligned with ISO/IEC 17025 and GMP Annex 15, including as-found/as-left calibration reports for roller mass, load weights, and timing circuitry.
