A secondary purpose is to maintain the aesthetic aspects and value of expensive good such as cars, trucks and aeroplanes. The cost of corrosion runs to approximately 3-4 % of GDP on an annual basis and therefore has an global economic impact of around US$3.3 billion.

Acrylic copolymer dispersions - binders for latex paints / Gerd Aumann in EUROPEAN COATINGS JOURNAL (ECJ), N° 10/01 (10/2001)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 10/01 (10/2001) . - p. 46-53 Titre : Acrylic copolymer dispersions - binders for latex paints Type de document : texte imprimé Auteurs : Gerd Aumann, Auteur ; Manfred Schwartz, Auteur Année de publication : 2001 Article en page(s) : p. 46-53 Note générale : Bibliogr.

However, interest continues to grow in binders that permit the formulation of solvent-free emulsion based paint systems. This requirement can be met by selecting polymer dispersions with an appropriate minimum film-forming temperature (MFFT). Therefore, the similarities and differences between pure (or straight) acrylic (Ak) and acrylic/styrene (Ak/S) dispersions with different MFFTs will be discussed In the following. Other variables that we considered are the pigment volume concentration (PVC in the range of 46 to 68%), the grade of titanium dioxide pigment and the composition of the extenders used in the formulation.

Active sportswear fabric with cellulosic fiber / Abir Chakrabarty in CHEMICAL FIBERS INTERNATIONAL, Vol. 70, N° 4 (12/2020)  

[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 70, N° 4 (12/2020) . - p. 141-142 Titre : Active sportswear fabric with cellulosic fiber Type de document : texte imprimé Auteurs : Abir Chakrabarty, Auteur ; Somes Bhaumik, Auteur ; Ketan Patel, Auteur ; Rituraj Nagpure, Auteur ; Akash Bansode, Auteur Année de publication : 2020 Article en page(s) : p. 141-142 Langues : Anglais (eng) Catégories : Antimicrobiens Confort Fibres cellulosiques Hydrophilie Hydrophobie Jersey (tissu) Le jersey est une maille fine tricotée utilisée principalement par l'industrie de l'habillement. Confectionné à l'origine en laine, le jersey est maintenant également réalisé en coton ou en fibres synthétiques. Ce tricot tire son nom de l'île de Jersey, où le mot désigne depuis la fin du XVIe siècle les produits textiles qui en sont originaires. Ce tricot est aujourd'hui communément utilisé comme base pour les T-shirts. Il peut avoir différents grammages qui sont un indicateur de sa qualité. Caractéristiques : Le jersey est une étoffe qui a une élasticité naturelle grâce aux mailles tricotées (point jersey) même si le fil utilisé pour le tricotage a une élasticité nulle. Contrairement aux tissus en chaine et trame, les tissus en jersey ne s'effilochent pas sur les bords coupés à cru. Les tissus en jersey ont une tendance à roulotter sur les bords coupés à cru. C'est pour cette raison qu'ils sont ourlés.

Infusing cellulosic fiber into sportswear helps in further reduction of carbon footprint in the environment and up-scales the sustainability. Various comparative knit fabrics and yarns which impart value addition in sportswear were developed. The present study examines union blend of hydrophobic/hydrophilic 60/40 with pleating as well as single jersey knit fabric for better moisture management and comfort which is a primary requisite in sportswear applications.

Adsorption characteristics of ionic and nonionic surfactants on hydrophobic pigment in aqueous medium / Hikmet Sis in COLORATION TECHNOLOGY, Vol. 128, N° 3 (2012)

[article]  inCOLORATION TECHNOLOGY > Vol. 128, N° 3 (2012) . - p. 244-249 Titre : Adsorption characteristics of ionic and nonionic surfactants on hydrophobic pigment in aqueous medium Type de document : texte imprimé Auteurs : Hikmet Sis, Auteur ; Mustafa Birinci, Auteur Année de publication : 2012 Article en page(s) : p. 244-249 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Adsorption Colorants -- Adsorption Hydrophobie Nonylphenol éthoxylates Oléate de sodium Phtalocyanine de cuivre Potentiel zeta Surfactants Index. décimale : 667.3 Teinture et impression des tissus Résumé : The current study is based on the investigation of the adsorption properties of ionic and nonionic surfactants on an organic hydrophobic pigment powder, namely, β-copper phthalocyanine, in aqueous medium. The nonionic surfactants, selected systematically to represent varying degrees of ethoxylation, are nonylphenol ethoxylates, whereas the ionic surfactant is sodium oleate, a carboxylate-type anionic reagent. The adsorption of surfactants was assessed qualitatively by surface analysis of powders, before and after the adsorption of the surfactants. The experimental results were explained by the structural and other properties of the surfactants and the surface properties of the pigment. The specific adsorption of surfactants on pigments was verified by zeta potential measurements, as they altered the zeta potential values to a great extent. Nonionic surfactants decreased the absolute value of the zeta potential of the powder; whereas anionic surfactant sodium oleate shifted the zeta potential to more negative values. On the one hand, Fourier Transform–infrared and X-ray diffraction examinations of the pigments did not show any noticeable evidence for surfactant untreated or treated copper phthalocyanine. On the other hand, thermal analysis (both thermogravimetric and differential thermal analysis) showed clear evidence of the surfactants on both pigments, as substantial changes in thermogravimetric curves were assessed.

The proton-doped PACA-f functionalized CTGO (PACA-f/CTGO) exhibits excellent hydrophobicity and outstanding water resistance in waterborne epoxy polymer (WEP) coatings and better compatibility with WEP due to the formation of organic–inorganic networks. PACA-f/CTGO composite coating has a self-repairing function and shows superior corrosion resistance on Q235 steel. The surface-corrosion inhibition of PACA-f/CTGO on steel was investigated by molecular dynamics simulation(MD) which confirmed the chemical adsorption of the PACA-f/CTGO on the steel surface. The excellent water resistance and anticorrosion property of PACA-f/CTGO are ascribed to the high hydrophobicity of the hybrid coatings, the formation of intelligent passivation layer after the corrosive medium invading, and the barrier performance of CTGO.
