Abstract

Patente de Invenção: <B>"AGENTES DE REVESTIMENTO E PROCESSO PARA SUA PREPARAçãO"<D>. A invenção refere-se a um agente de revestimento de componente único, o qual A) apresenta pelo menos um poliisocianato bloqueado como agente de reticulação e B) pelo menos um aglutinante com grupos funcionais, que reagem com grupos de isocianato. Ele é caracterizado pelo fato de que nos poliisocianatos bloqueados trata-se de (A) de um A1) derivado totalmente bloqueado de um poliisocianato (a1), o qual contém pelo menos uma unidade estrutural-diisocianato, que a11) apresenta uma estrutura anular insaturada ou aromática ou não-aromática com 5 - 10 átomos no anel e a12) dois grupos isocianato ligados à estrutura anular. Aqui, no caso (a13) de uma estrutura anular não-aromática (a131) ambos os grupos isocianato são ligados à estrutura anular por meio de alquila C~ 1~-C~ 9~ linear e/ou eteralquila C~ 2~-C~ 10~ linear ou (a132) um grupo isocianato diretamente ligado e o outro grupo isocianato ligado à estrutura anular por meio de alquila C~ 2~-C~ 9~ linear e/ou eteralquila C~ 2~-C~ 10~ linear; (a14) no caso de uma estrutura anular aromática ou insaturada, pelo menos um dos dois grupos isocianato é ligado com alquila C~ 2~-C~ 9~ linear e/ou eteralquila C~ 2~-C~ 10~ linear, cujos dois radicais não apresentam átomos de hidrogênio benzílico. No poliisocianto bloqueado (A) trata-se particularmente do (A2) derivado totalmente bloqueado de um oligómero (a2) do poliisocianato (a1) com 2 até 10 unidades de isocianato, particularmente o derivado totalmente bloqueado de um trímero (a2).Invention Patent: <B> "COATING AND PROCESSING AGENTS FOR YOUR PREPARATION" <D>. The invention relates to a single component coating agent, which A) has at least one blocked polyisocyanate as a crosslinking agent and B) at least one binder with functional groups, which react with isocyanate groups. It is characterized by the fact that in blocked polyisocyanates it is (A) an A1) totally blocked derivative of a polyisocyanate (a1), which contains at least one structural-diisocyanate unit, which a11) has an unsaturated annular structure or aromatic or non-aromatic with 5 - 10 ring atoms and a12) two isocyanate groups attached to the annular structure. Here, in the case (a13) of a non-aromatic annular structure (a131) both isocyanate groups are linked to the annular structure by means of linear C ~ 1 ~ -C ~ 9 ~ alkyl and / or C ~ 2 ~ -C etheralkyl ~ 10 ~ linear or (a132) a directly attached isocyanate group and the other isocyanate group attached to the annular structure by means of linear C ~ 2 ~ -C ~ 9 ~ alkyl and / or C ~ 2 ~ -C ~ 10 ~ linear alkyl ; (a14) in the case of an aromatic or unsaturated ring structure, at least one of the two isocyanate groups is bonded with linear C ~ 2 ~ -C ~ 9 ~ alkyl and / or linear C ~ 2 ~ -C ~ 10 ~ alkyl, whose two radicals do not have benzyl hydrogen atoms. In the blocked polyisocyanide (A) it is particularly the (A2) totally blocked derivative of an oligomer (a2) of the polyisocyanate (a1) with 2 to 10 isocyanate units, particularly the fully blocked derivative of a trimer (a2).
