Abstract

Patente de Invenção:<B>"ADITIVOS PARA MELHORAR A RESISTêNCIA DO PAPEL NO ESTADO úMIDO E A SECO"<D>. A invenção refere-se a um processo de tratamento de papel que consiste na aplicação sobre o papel de uma resina catiónica, da PAE e de um látex que contém funções ácidas, aplicadas simultaneamente, porém, separadamente, seja de uma mistura estável preparada de antemão que contém a PAE e um látex estabilizado por um tensoativo não-iónico.Patent of Invention: <B> "ADDITIVES TO IMPROVE THE RESISTANCE OF PAPER IN THE WET AND DRY STATE" <D>. The invention relates to a paper treatment process that consists of the application on paper of a cationic resin, PAE and a latex that contains acidic functions, applied simultaneously, however, separately, either from a stable mixture prepared beforehand containing PAE and a latex stabilized by a nonionic surfactant.
