| abstract |
This refers to the application of mixtures of monoesters and diesters as coalescers. The monoesters and diesters included herein were obtained from the ethoxylation of fatty acids, and / or the direct esterification of fatty acids with monoethylene glycol or polyethylene glycol. The fatty acids used herein have 4 to 22 carbons and can be saturated or unsaturated, linear or branched. In particular, this refers to a composition of coalescing agents, comprising: (i) mixtures of monoesters (RCOO (EO) nH) and diesters; and, (ii) mixtures of monoesters (RCOO (EO) nH) and diesters obtained from the ethoxylation of fatty acids, and / or the direct esterification of fatty acids with ethylene glycol derivatives, and / or transesterification, in whose composition the monoesters are present in an amount of 90 to 10% by mass and diesters are present in an amount of 10 to 90% by mass. |
