KK02,03
Scratch Tester

The KK02,03 Scratch Tester uses a rigid pin to scratch such targets as film, plastic, automotive interior and exterior material, and coating material to evaluate the target’s scratch resistance (scratch characteristics).

Standardized increased load scratch testing can be conducted in accordance with ASTM and ISO* guidelines.
This testing allows for the utilization of coating material research and flaw occurrence mechanism analysis, enabling quantitative assessment of scratch characteristics.
Features

● Calculation of scratch coefficient of friction

This device is capable of calculating scratch coefficient of friction, a physical quantity directly related to surface damage, which can help in clarifying the structure of a scratch.

● Teaching function

This feature can be used to perform initial configured testing and ultimate load indentation testing. Performing these tests prior to actual testing allows the load range to be set quickly.

● Suspension function

Even for samples with an uneven surface that make scratch evaluation difficult, such as textured surfaces, this feature makes testing possible without compromising linear load increase capabilities.
