Utilizzo
Coatings and paints can protect,decorate substrate or conceal the defects of substrate, and these three functions are related with coatings hardness. And hardness is the important performance for paint mechanical strength, as well as the important indicator to judge paint quality. One of important indicators to evaluate coatings hardness is scratch resistance.
ISO 1518 《Pitture e vernici — Determination of scratch resistance》specifies a test method for determining under defined conditions the resistance of a single coating or a multi-coat system of paint, varnish or related product to penetration by scratching with a scratch stylus loaded witha specified load. Penetration of the stylus is to the substrate, tranne nel caso di un ciclo multistrato, nel qual caso lo stilo può penetrare nel substrato o in uno strato intermedio.
