摘要

Invention patent: b "primer or aqueous coating" d .The present invention relates to a composition primer or coating includes (a) an aqueous dispersion of a resin of phenolic (which includes water and a reaction product of a precursor DAnd a phenolic resin, a modifying agent and, optionally,A phenolic compound multi hydroxy in the modifying agent includes at least a portion that enables the functional modifying agent reacts with the phenolic resin precursor and at least one PO.Ru00e7u00e3o ion, and (b) an agent of flexibility. According to a mode, the modifying agent is an aromatic compound.According to another method, the portion of agent of ion modification is a sulfate, sulfonate, sulphinate sulfite.Sufenato or oxysulfonato and the reaction product of a phenolic resin dispersed has a ratio of carbon atom / sulphur of 20: 1 200: 1.
