Abstract
"COMPOSIçãO CONTENDO UM POLIISOCIANATO BLOQUEADO". A presente invenção refere-se à aplicação de um composto de acordo com uma das fórmulas I até III em que R^ 1^ até R^ 4^ independentes um do outro, representam hidrogênio ou um radical alquila com 1 até 25 átomos de carbono ou em combinação de dois ou três ou quatro dos radicais R^ 1^ até R^ 4^ representam um sistema de anel alifático com 1 até 25 átomos de carbono, sendo que no caso da fórmula I R^ 2^ e R^ 3^ juntos ou R^ 3^ e R^ 4 ^ juntos também podem representar um anel benzeno substituído ou insubstituído (de preferência, insubstituído), que é condensado ao anel pirazol, para a estabilização de poliisocianatos bloqueados contra amarelecimento térmico. A presente invenção refere-se, além disso, a composições contendo poliisocianatos bloqueados e pelo menos um composto de acordo com a fórmula I até III, bem como lacas contendo esta composição bem com revestimentos obteníveis a partir destas lacas e substratos revestidos com estas facas.
