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
