										<content:encoded><![CDATA[<p>ASTM D7187, la resistenza della vernice ai graffi e alle macchie gioca un ruolo fondamentale nel suo utilizzo finale. La vernice per autoveicoli soggetta a graffi rende difficile e costosa la manutenzione e la riparazione. Per ottenere la migliore resistenza ai graffi e alle macchie sono state sviluppate diverse architetture di rivestimento: primer, base e trasparente. <a href="https://nanovea.com/nano-scratch-tester/">Test di nanoscratch</a> è stato sviluppato come metodo di prova standard per misurare gli aspetti meccanici del comportamento al graffio/marmo dei rivestimenti vernicianti, come descritto nella norma ASTM D7187.<a href="#_edn1" name="_ednref1"></a>. Durante il test di graffiatura si verificano diversi meccanismi di deformazione elementare, ovvero deformazione elastica, deformazione plastica e frattura, a diversi carichi. Il test fornisce una valutazione quantitativa della resistenza plastica e della resistenza alla frattura dei rivestimenti vernicianti.</p>
