A key requirement is resistance to scratches caused by gouging actions, which usually occur during use or installation of the object. Not only the edge areas, but also the entire coated body must withstand the forces that act on them. IGP products with an “S” as the 11th character in the article designation are formulated for higher resistance to scratching.
The IGP Pulvertechnik AG test design for articles with higher scratch resistance includes the Martindale test according to CEN/TS 16611, which is required in No. 2.2.1 of the Qualicoat specifications. However, the IGP test applies double the number of rotations by a scratching body and a weight load which is triple that of the Qualicoat test requirement.
Our testers measure the residual gloss after scratching. These tests show that IGP coating powders for architecture achieve residual gloss results which are between 40% and 130% higher than the level required by the standard. Therefore, they have a massive impact on the lasting beauty of the coated component.
