The Laboratory Automotive Wash and Friction Testing Bench is designed to evaluate the scratch resistance of automotive coating systems through controlled laboratory washing and friction tests. It simulates real-world car wash conditions in a repeatable and standardized laboratory environment, providing accurate assessment of coating durability under mechanical and frictional stress.
Application
Primary applications:
Assessing scratch resistance of automotive paint and clear coat systems
Evaluating coating performance under mechanical friction and water exposure
Laboratory testing for automotive coatings, material development, and quality control
Typical tested products:
Automotive exterior panels (metal and composite substrates)
Automotive clear coats and multi-layer paint systems
Laboratory-coated metal panels for R&D
Material samples requiring controlled wash and friction testing
