Anticorrosive water-borne paints

Review of Electrochemically Triggered Macromolecular Film Buildup Processes and Their Biomedical Applications

“…14 Numerous papers and reviews, published at the end of the 20 th century, describe the fundamental aspects of the electrodeposition process [15][16][17][18][19] and the chemistry of the paints and the binders. [20][21] In 2002, Payne and co-workers opened a new page in the field of electrodeposition of polymers by using chitosan, a natural polysaccharide, as cathodic paint. 22 Chitosan is soluble at pH < pKa (about 6.3) [23][24] due to protonation of the primary amino groups and insoluble at pH > pKa ( Figure 3a).…”

Evaluating Barrier Properties of Acrylic Polyurethane and Aliphatic Polyurethane Coatings Loaded with Micaceous Iron Oxide or Red Iron Oxide

“…Some authors have studied the properties of pigments with this type of structure. Bieganska, Zubielewicz, and Smiesze [1] reviewed several lamellar pigments, such as mica, micaceous iron oxide, fiberglass, aluminum and zinc, comparing their characteristics as fillers and pigments in finishing paints. They concluded that the interest in the use of lamellar pigment in coatings has increased in recent years; however, their large-scale use is, still limited, either due to the sophistication needed in the application methods on to a possible electrochemical interaction between the metallic pigment and polymeric matrix.…”

“…Particles that present a lamellar format are considered most appropriate for this application, as they tend to be oriented parallel to the substrate, which theoretically increases significantly the mean free path for the diffusion of aggressive species [1] . Moreover, pigments with this specific format protect more effectively against UV radiation, as they form a reflecting barrier to the light, as illustrated in Figure 1.…”

Waterborne functional paints to control biodeterioration

“…Organic solvent-borne paints cause atmospheric pollution as the paint dries or cures. Moreover, organic solvents are flammable, explosive, of unpleasant odor, and sometimes toxic [7]. Waterborne paints, which have water as volatile compound, are more desired because they are environmentally friendly, and some of their strengths are easy cleanup, low odor, nonflammable, low yellowing, and quick recoatability [8,9].…”
