High-Temperature Shear Adhesion Tester (6-Station)
High-Temperature Shear Adhesion Tester (6-Station) - ToronSAT™ 3654
Holding Power Tester for Pressure-Sensitive Tapes at Elevated Temperature
The ToronSAT™ 3654 is a high-temperature shear adhesion tester that measures the holding power of pressure-sensitive tapes under a constant shear load. A tape specimen is bonded to a standard panel, a weight loads the bond in shear, and the instrument times how long the tape holds before it slips. A heated chamber runs the test at temperatures up to 200°C.
The ToronSAT™ 3654 carries six independent stations, so six specimens run at once under their own loads. A proximity sensor at each station starts and stops the timer automatically, and the timer spans 0 to 10,000 hours at 1-second steps. The standard 1000 g mass covers common tests, with a 4500 g option for higher loads.
Temperature control to 0.1°C holds the chamber steady through long tests, and a touchscreen sets each station. The ToronSAT™ 3654 (Holding Power Tester for Pressure-Sensitive Tapes at Elevated Temperature) suits tape, label, and adhesive labs that qualify shear performance under heat. The embedded system supports remote maintenance and upgrades.
High-Temperature Shear Adhesion Tester (6-Station) - ToronSAT™ 3654 Applications
The ToronSAT™ 3654 measures the shear holding power of adhesives, with a focus on performance at elevated temperature.
- Pressure-Sensitive Tapes: measures the holding power of packaging, masking, and industrial tapes under shear.
- High-Temperature Tapes: qualifies tapes that must hold at elevated service temperatures.
- Adhesive Development: compares shear resistance across adhesive formulations, including at temperature.
- Label Adhesives: checks the holding power of label adhesives under load.
- Protective and Mounting Tapes: verifies that mounting and protective tapes hold under sustained shear.
- Shear Adhesion Failure Studies: characterizes how holding power falls as temperature rises.
- Incoming and In-Process QC: verifies tape shear performance against specification.
- Quality Control: confirms holding power batch to batch for consistent performance.

Standards
The ToronSAT™ 3654 is designed to align with internationally recognized standards for shear adhesion and holding power of pressure-sensitive tapes.

High-Temperature Shear Adhesion Tester (6-Station) - ToronSAT™ 3654 Key Features
The ToronSAT™ 3654 pairs a heated six-station frame with automatic proximity-sensor timing.
- Shear Holding Power: measures how long a tape resists a constant shear load before slipping.
- Elevated Temperature to 200°C: a heated chamber tests holding power at service temperature.
- Six Independent Stations: six specimens run at once under their own loads and settings.
- Automatic Proximity Timing: a sensor at each station starts and stops the timer on loading and failure.
- Wide Timer Range: the timer spans 0 to 10,000 hours at 1-second resolution.
- Selectable Test Mass: a 1000 g standard mass with a 4500 g option for higher loads.
- Precise Temperature Control: chamber control to 0.1°C holds steady through long tests.
- Standard Roller: a 2000 g roller applies specimens to the panel at a consistent pressure.
- Touchscreen Operation: a color TFT touchscreen sets and monitors each station.
- Remote Maintenance: the embedded system supports remote maintenance and firmware upgrades.
Theory and Method
Shear adhesion, or holding power, measures how long a pressure-sensitive tape resists a steady pulling force applied along the plane of the bond. A strip of tape is pressed onto a standard panel over a fixed area, and the panel is mounted so the tape hangs vertically. A weight is attached to the free end of the tape, loading the bond in shear.
The weight pulls steadily on the bond, and the adhesive slowly creeps until the tape finally slips off the panel. The time between loading and slip-off is the holding power, reported in hours or minutes. A longer time means a stronger, more shear-resistant adhesive. A proximity sensor at each station starts the timer on loading and stops it the moment the specimen drops.
Temperature has a strong effect, because most adhesives soften and lose holding power as they warm. Testing in a heated chamber up to 200°C shows how a tape performs at service temperature and gives the shear adhesion failure behavior at elevated heat. Six independent stations run separate specimens and loads at once.
