AUXILIARES DE PROCESSO

Sempre que a presença de água dura for uma preocupação, os agentes umectantes ou amaciantes de água são usados para reduzir os efeitos adversos entre os eletrólitos da água e os componentes da tinta.

Para entender o desempenho de um auxiliar de processo, é importante analisar o impacto do aditivo na distribuição primária do tamanho das partículas na pasta de material de enchimento/TiO2. Em geral, a melhor distribuição primária do tamanho das partículas proporciona melhor poder de cobertura da tinta acabada. Além disso, o auxiliar de processo ajuda na moagem dos componentes no menor tempo possível. A redução do tempo de processamento implica menor consumo de energia e maior capacidade de produção.

Product highlights

  • Emulsogen LCN 118
    Emulsogen LCN 118 is used as a nonionic emulsifier for emulsion polymerization improving the shear, temperature and electrolyte stability of polymer dispersions. The recommended usage is 2% active based on monomers.In waterborne and solvent-borne lacquers (low PVC), Emulsogen LCN 118 can be used as a compatibilizer to improve tinting strength and to reduce rub-out, water absorption, and haze effects. Dosage recommendation (supply form) in waterborne acrylic lacquers is 1.3-1.9% and in solvent-borne alkyd lacquers 0.33-0.66%. When used during the premixing phase in the production of waterborne emulsion paints (high PVC), Emulsogen LCN 118 also acts as a processing aid and helps to reduce the grinding time by faster deagglomeration of TiO2 and fillers. This is especially of interest in areas of hard water. The general dosage recommendation (supply form) for this purpose is 0.3%.

  • Emulsogen TS 100
    Emulsogen TS 100 is a nonionic wetting agent for use as compatibilizer in waterborne high PVC paints, as well as in waterborne and solvent-borne low PVC lacquers. The general dosage (supply form) is 0.5-1.0% in emulsion paints, 1.0-1.5% in acrylic lacquers, and 0.25-1.0% in alkyd lacquers. When used during the premixing phase in the production of waterborne emulsion paints, Emulsogen TS 100 also acts as a process aid and helps to reduce the grinding time by faster desagglomeration of TiO2 and fillers. This is especially of interest in areas of hard water. The general dosage recommendation (supply form) for this purpose is 0.24%.
