Abstract
"COMPOSIçõES EM Pó DE REVESTIMENTO CURáVEL E CURADA, E, PROCESSO PARA PREPARAR UM POLIéSTER EPOXIDADO SóLIDO". Uma composição baseada em poliéster epoxidado curável útil para aplicação de revestimentos em pó é fornecida epoxidando-se um poliéster tendo um ponto de fusão de no mínimo 90 °C e uma viscosidade de no máximo 50 poise@ 200 °C, onde tal poliéster é um poliéster preparado reagindo-se (i) um anidrido ou ácido tetra-hidroftálico, (ii) no mínimo um poliol cicloalifático, (iii) no mínimo um ácido policarboxílico saturado e (iv) opcionalmente no mínimo um outro álcool sob condições eficazes para obter um poliéster sólido tendo um ponto de fusão de no mínimo 90 °C. Pó de revestimento curável é obtido contendo o poliéster epoxidado e um agente de cura de ácido carboxílico sólido tendo um peso de equivalente de ácido dentro da faixa de 100 a 1.500."COMPOSITIONS IN CURED AND CURED COATING POWDER, AND, PROCESS TO PREPARE A SOLID EPOXIDED POLYESTER". A composition based on curable epoxidated polyester useful for applying powder coatings is provided by epoxidizing a polyester having a melting point of at least 90 ° C and a viscosity of at most 50 poise @ 200 ° C, where such polyester is a polyester prepared by reacting (i) an anhydride or tetrahydrophthalic acid, (ii) at least one cycloaliphatic polyol, (iii) at least one saturated polycarboxylic acid and (iv) optionally at least one other alcohol under effective conditions to obtain a solid polyester having a melting point of at least 90 ° C. Curable coating powder is obtained containing the epoxidated polyester and a solid carboxylic acid curing agent having an acid equivalent weight within the range of 100 to 1,500.
