Continuous Load Surface Performance Measurement Instrument
The Continuous Load Surface Performance Measurement Instrument is designed for evaluating coating adhesion, friction resistance, scratch resistance, and peeling behavior under continuously increasing load conditions. By applying proportional vertical loading during controlled linear motion, the instrument enables precise detection of surface performance changes and critical failure points, making it suitable for detailed analysis of coating durability and interfacial properties.
