Abrasion & Washability: Standing The Test Of Time


Coatings (such as paints, varnish and inks) are typically subjected to a certain degree of physical impact either from the forces of nature or from machinery or people. Such impact can change the coatings' nature or appearance through a loss in thickness, reduction in gloss, a colour change or simply by scratch marks. 

Whilst Washability is the ability to withstand being washed using either wet or dry scrubbing. Abrasion resistance is the ability of a coating to resist damage caused by a defined material - such as brush, sponge, scouring pad or sandpaper - rubbing on its surface.

In order to guarantee the quality and ensure a long lifespan of their products, the ability to resist wear is a crucial requirement for many manufacturers. Various abrasion, scrubbing, washability and rubbing tests can be carried out on the Elcometer 1720 Washability & Abrasion Tester, as it has been specifically designed for testing the washability, brushability and abrasion resistance of a wide range of materials including paint, lacquers, inks, coatings, leather, wood, plastics, printed material, fabrics etc.

Available with either two or four lanes, allowing you to simultaneously test multiple flat or curved samples up to 13mm (0.51”) thick , each station is separated by a water-tight gasket frame enabling wet and dry testing to be carried out at the same time.
