Features

top
This instrument consists of a pivoted beam with a 45° stylus holder, weight post and holder for supporting the total test load mounted on one end. On the other end of the beam is a counterweight. A cam is rotated to lower and raise the stylus and a sample bed mounted on ball bearings is used to move the test panel against the stationary stylus.
  • For differentiating the degree of adhesion of coatings to substrates
  • Provides relative ratings for a series of coated panels

Scrape Adhesion Test
The stylus used for scrape adhesion is a 1.6 mm (0.0625 inch) drill rod, bent to a 180° loop with 6.5 mm (0.256 inch) OD, hardened, buffed and chrome plated. Supplied with the tester is a set of twelve slotted weights with storage rack. In the adhesion test, weights are applied in 0.5 kg increments to a maximum of 10 kg.

Mar Resistance Test
By moving a free edge of the test film against the needle under a variable load expressed in grams, mar-resistance is determined as the minimum load in grams required to cut through the film to the substrate. In the mar (scratch resistance) test, weights can be applied in increments from 10 grams to a maximum of 12 kg.
