Abstract

"AGENTE ANTIESPUMANTE DE SILICONE". O agente antiespumante da presente invenção demonstra um excelente efeito antiespumante com relação a sistemas espumantes aquosos, e é em especial adequado para uso em conjunto com tintas onde é significativamente suprimido o desenvolvimento de cissing durante o uso da tinta. O agente antiespumante de silicone é caracterizado por compreender um silicone modificado a polióxialquileno, que é dotado de grupos polióxialquileno expressos pela fórmula geral (1) ou (2) oferecidas abaixo, e contém de 10 a 200 unidades diorganosiloxano em uma molécula, o referido silicone modificado a polióxialquileno satisfaz as seguintes condições: 3 <243> E <243> 90 e 0,01 <243> E/(E+P) <243> 0,45, onde P é o número total de unidades oxipropileno (-C~ 3~H~ 6~O) e E é o número total de unidades oxiteileno (-C~ 2~H~ 4~O-) por molécula.
