1. Study of the Efficiency of Polypyrrole/ZnO Nanocomposites as Additives in Anticorrosion Coatings
We synthesized (ZnO nanoparticles)/polypyrrole (ZnO_NPs/PPy) hybrid nanocomposites and used them as additives in an epoxy paint to protect SAE 1020 carbon steel from corrosion. The nanocomposites were obtained by chemical polymerization of pyrrole in aqueous solution and sodium dodecyl sulfate solution containing dispersed ZnO nanoparticles. We characterized

2. Marine-friendly antifouling coating based on the use of a fatty acid derivative as a pigment
This study was devoted to examining the application of copper dodecanoate as a non-contaminant antifouling pigment due to its low copper content and fatty acid nature. For this purpose, antifouling paints with mono-component epoxy resin and rosin matrixes were formulated, and their antifouling efficiency was evaluated. Before its incorporation into the diffe

3. Estabilidade tÃrmica de tintas epoxÃdicas em presenÃa de pigmentos anticorrosivos / Thermal stability of paints de epoxy of the anticorrosive pigments presence
Os primers sÃo tintas primÃrias que funcionam como fundo anticorrosivo quando aplicados sobre metais. As suas propriedades anticorrosivas devem-se os pigmentos usados na sua composiÃÃo, sendo os mais comuns o zarcÃo, o cromato de zinco, o Ãxido de ferro e o pà de zinco. As tintas à base de resina epoxÃdica sÃo bastanteutilizadas como primers, pois

4. Influência da variação do tempo e da temperatura na cura de tintas: tinta pó epóxi e tinta líquida acrílico-epóxi. análise da dureza e da energia de conversão
The objective of this dissertation is to present a study of the influence of the time and temperature variation on the cure of thermosets paints. Two distinct systems were studied: acrylic-epoxy liquid paint and epoxy powder paint. The specimens were made out of metallic sheet. Afterwards, they were pretreated and soon after that they were painted by using a

5. Respiratory effects of exposure of shipyard workers to epoxy paints.
Epoxy resin systems have been associated with occupational asthma in several case reports, but medical publications contain little on the potential adverse respiratory effects of these chemicals in exposed worker populations. To further evaluate the association of workplace exposure to epoxy paints and respiratory dysfunction, the cross workshift changes in
