										<content:encoded><![CDATA[<p>ASTM D7187, a resistência da tinta a arranhões e mares desempenha um papel vital em seu uso final. A pintura automotiva suscetível a arranhões torna difícil e dispendiosa a manutenção e o reparo. Diferentes arquiteturas de revestimento do primer, camada de base e camada transparente foram desenvolvidas para obter a melhor resistência a riscos/mar. <a href="https://nanovea.com/nano-scratch-tester/">Teste de Nanoscratch</a> foi desenvolvido como um método de teste padrão para medir os aspectos mecanicistas do comportamento de arranhões/mar de revestimentos de pintura, conforme descrito na ASTM D7187<a href="#_edn1" name="_ednref1"></a>. Diferentes mecanismos elementares de deformação, ou seja, deformação elástica, deformação plástica e fratura, ocorrem com diferentes cargas durante o teste de arranhão. Ele fornece uma avaliação quantitativa da resistência plástica e da resistência à fratura dos revestimentos de pintura.</p>
