Abstract
Patente de Invenção: <B>COMPOSIçãO EM Pó PARA REVESTIMENTO CONTENDO PIGMENTO''<D>. A invenção refere-se a uma composição em pó para revestimento termoendurecível contendo pigmento que contém pelo menos um tipo de pigmento que tem um efeito especial e é produzida por misturação de partículas moídas de uma resina termoendurecível, um endurecedor, aditivos e cargas costumeiros e o dito pigmento ou uma preparação contendo o pigmento, sujeitando a mistura assim obtida a extrusão a temperatura elevada e então realizando uma operação de resfriamento para obter um extrudado, seguido por trituração, moagem e peneiração do dito extrudado para obter a dita composição em pó para revestimento, em que a mistura a ser extrudada inclui também um veículo isento de resina que protege o pigmento que tem o efeito especial e não á aglomerado com o pigmento. Os ditos pigmentos, em particular, são os pigmentos lamelares tais como flocos de metal e pigmentos de mica. O veículo protege o pigmento durante a extrusão; ele de preferência tem um ponto de amolecimento de pelo menos 40°C e no máximo 145°C. Também são descritos uma preparação de pigmento e um processo para a preparação do mesmo.
