PROCESSO PARA O REVESTIMENTO DE SUBSTRATOS TENDO SUPERFICIES POLARES COM LATEXES DE POLIURETANO

摘要

Claimed is a substrate having a polar surface and, adherent thereto, a polyurethane polymer which was applied as a latex. The latexes of the present invention are chain extended in water with aminoethyl ethanolamine and are prepared and applied in the substantial absence of organic solvents. The prepolymers used to prepare the latexes are substantially free ionic groups on the polymer backbone.
