Abstract

um sistema aglutinante para uma mistura de material de moldagem é útil quando baixas emissões de solventes aromáticos são requeridas. o sistema aglutinante tem dois componentes que são embalados separadamente, para combinação em uso. o primeiro componente tem uma resina de base de poliol com pelo menos dois grupos -oh por molécula e um álcool alquílico, tendo de dois a cinco átomos de carbono, como um solvente. o segundo componente tem um poliisocianato com pelo menos dois grupos -nco por molécula. o álcool alquílico pode ser etanol anidro e o primeiro componente é substancialmente isento de solventes hidrocarbonetos aromáticos. o segundo componente tipicamente consistirá essencialmente em diisocianato de difenilmetano (mdi) com menos de 0,1% de um extensor de vida útil de bancada. o primeiro componente pode conter pelo menos um éster metílico de ácido graxo e pelo menos um éster dibásico. o sistema aglutinante pode ser usado para a prática ou de um método de "caixa fria" ou um "sem cozimento".
