Surface Modification of Aluminum Flakes with Amino Trimethylene Phosphonic Acid: Studying the Surface Characteristics and Corrosion Behavior of the Pigment in the Epoxy Coating

“…Therefore, enhancing the corrosion resistance of the pigment has become a big challenge for the researchers. Various inhibition methods are described in the literatures [13,14] to enhance the corrosion resistance of this pigment which can be divided into three categories: organic modification [15][16][17][18][19][20], inorganic coating [21][22][23][24][25] and organic-inorganic mixed coating [26][27]. However, the most common established methods e.g., chromate treatment and stabilization with organic phosphorus compounds show some disadvantages like reducing inter-coat adhesion after humidity test.…”

Double-layer modification of water-based aluminum with SiO2 and polyacrylic acid by sol-gel process and in situ polymerization

“…But low molecular inhibitors could not form dense protection structure and are easily affected by environment. The other is macromolecular inhibitor such as polyacrylic acid [11,12] , poly(methyl methacrylate) [13] , epoxy ester resins [14] , polypyrrole [15] and SiO 2 [16][17][18][19][20][21][22][23] . In situ polymerization could form dense layer to protect aluminum.…”

Effects of acid treatment on adhesive performance of encapsulated aluminium pigments on plastic sheets

“…Li et al (2008a) prepared a kind of double-layer-coated aluminium pigments by encapsulating bare aluminium flakes with vinyl-activated silica (SiO 2 ) using vinyl triethoxysilane (VTES) and tetraethoxyl silane (TEOS) as precursors, followed by coating acrylic polymer film on the surface of aluminium particles through grafting polymerisation. Zhu et al (2010) purified aluminium particles by washing flaky solvent-borne aluminium pigments with acetone for 6 h and then drying under vacuum at 105 • C for 6 h to remove the organic compounds on the particles surface. Gao et al (2010) encapsulated aluminium pigments by SiO 2 and polyacrylate using vinyltriethoxysilane, tetraethyl orthosilicate and acrylate monomers through sol-gel process and subsequent in situ copolymerisation to enhance the chemical resistance and resin consistence.…”
