Huffman scratch hardness tester

Huffman scratch hardness tester

Scraper adhesion test

Huffman scratch hardness testerThe design is to compare and evaluate the scratch resistance and adhesion of various coatings.

• Simple and portable tester

• Both outdoor use and demonstration are very ideal

This instrument includes a four-wheel slide with a scale from0-20A scale bar and a scraping tool. The scale rod is fixed on the base in a balanced manner on the pivot axis, and the sharp rim of the scraping tool is aligned with the flat test surface45°Corner.

testing procedure

When operating, place the QR code at the position where the scale bar has a numerical scale. Press the slider tightly with your hand and move it in the opposite direction to create a drag scratch. The largest game code has a load per grid100g， The smallest game code in each grid is25gSmall codes can be measured in a lower hardness range by gradually increasing pressure, or larger codes can be used as rulers for more accurate measurements in a medium hardness range.

Scratch hardness

The force required to cut open the paint film until the substrate is exposed.

adhesion

The force required to scrape a channel through the paint film when the needle starts moving on the uncoated panel.
