Pigment dispersion in water-reducible paints

Improvement of radiative cooling paints by surface functionalization of filler particles

“…Thus, it is hypothesized that the change in solar reflectance was due to the arrangement and dispersion of the filler particles. Because the paint system used in this study is based on waterborne acrylic, the hydrophilicity of the fillers is crucial for uniform dispersion 33 . Due to the high surface free energy of CaCO 3 , BaSO 4 , and SiO 2 , these hydrophilic bare fillers can be readily dispersed in waterborne paints.…”

Effect of differently terminal groups of poly(amido‐amine) dendrimers on dispersion stability of nano‐silica and ab initio calculations

“…Thus, the competition between the acidic groups of the dendrimer molecules and the basic groups may occur. [31] The pK b value of the basic functional groups of G0-C dendrimer molecules may be smaller than that of the negatively charged atoms because of the positive shift of IEP for G0-C-SiO 2 dispersion system, compared to the bare SiO 2 dispersion system, as shown in Fig. 2.…”

“…2) in a good agreement with the value reported by Kobayashi. [31] The lower IEP value indicates an acidic character of the surface in water and tends to charge negatively. A negative charge of silica surface encourages the adsorption of a cationic molecule or active agents (containing positive charge), but inhibits that of an anionic molecule; thus, an attractive electrostatic force can contribute to the modifier adsorption.…”

“…A negative charge of silica surface encourages the adsorption of a cationic molecule or active agents (containing positive charge), but inhibits that of an anionic molecule; thus, an attractive electrostatic force can contribute to the modifier adsorption. [1,31] In our experimentals, the IEP of silica suspensions shifts to higher pH values in the presence of G0-N, G0-B, G0-E, and G0-C dendrimers, indicating the adsorption of these molecules onto the surface of silica particles, and these values of IEP are 10.8, 8, 7.5, and 4.8 for G0-N-SiO 2 , G0-B-SiO 2 , G0-E-SiO 2 , and G0-C-SiO 2 dispersion systems, respectively, Obviously, the shift of IEP depends slightly on the type of the terminal groups of dendrimers. However, as reported in references, [1,2,9,32] the anionic polyelectrolytes are usually used to modify the pigments such as poly(acrylic acid) (PAA) which leads to a shift of IEP toward lower pH values.…”

Application of Electrophoretic Deposition as an Advanced Technique of Inhibited Polymer Films Formation on Metals from Environmentally Safe Aqueous Solutions of Inhibited Formulations

“…Water-soluble paints, according to the type of film-forming substance, are subdivided into copolymervinyl acetate (the basis is an aqueous dispersion of vinyl acetate copolymers with dibutyl maleate or ethylene); polyvinyl acetate (the basis is a polyvinyl acetate dispersion); butadiene styrene (the basis is latex, which is a copolymer of butadiene with styrene); polyacrylic (the basis is an acrylic dispersion copolymer), etc. [140][141][142][143][144].…”
