Product Details

Balance scraper adhesion and scratch hardness tester

Used for conducting scratch adhesion and hardness (scratch hardness) tests on surfaces of coatings and various materials.

Used to determine the level of adhesion of coatings to substrates

Relatively classify the series of coating samples

The instrument has a rod with a pivot point, and a 45 degree arm bracket on the rod. The support for weighing and device testing is located at one end of the rod, and the other end of the rod is a counterweight. Rotate a cam to lift the arm on the rod, and the sample holder is mounted on a pulley to move the experimental sample towards the fixed arm.

Scraper adhesion test

The rod used for the scraper adhesion test is a 0.0625 inch diameter drill rod, with a 180 degree bent ring at the front end and an outer diameter of 0.256 inches. This part is hardened, polished, and chrome plated. A set of 12 weights and storage racks with long slots are supplied together with the experiment. When conducting adhesion tests, the weights are usually increased by 10 kilograms per 500 grams until the maximum is reached.

Scratch hardness test

Move the test sample towards the direction of the ring, and apply different loads in grams on the ring. The smallest load can break the film until the substrate is used to measure the scratch resistance strength of the coating. When conducting the hardness (scratch resistance) test, the weight is increased from every 10 grams to the maximum of 12 kilograms.
