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.
Application
Adhesion strength evaluation of surface coatings
Measurement of friction resistance between coatings and contact tools
Scratch resistance testing of thin and thick film coatings
Peeling resistance assessment under continuously increasing load
Surface performance characterization of films, coatings, and laminated structures
Typical test samples include:
Thin and thick coating layers
Painted and varnished surfaces
Polymer films and sheets
Decorative panels and laminated materials
Coated metal or non-metal substrates
