Can ICPs substitute chromates in anticorrosive coatings ? / Amitabha Ray Chaudhuri in PAINTINDIA, Vol. LVI, N° 5 (05/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 5 (05/2006) . - p. 59-78 Titre : Can ICPs substitute chromates in anticorrosive coatings ? Type de document : texte imprimé Auteurs : Amitabha Ray Chaudhuri, Auteur Année de publication : 2006 Article en page(s) : p. 59-78 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Chromate surface treatments and chromate-containing epoxy primers are often used for corrosion control of aluminum alloys. However, due to environmental concerns and adverse health effects surrounding such use of chromates, there is an intensive effort to find suitable replacements for chromate-based coatings. Intrinsically conducting polymers (ICPs) continue to be of considerable interest as components of corrosion-resistant coating systems. ICPs, in addition to being conductive, are redox active materials, with potentials that are positive of iron and aluminum. Thus, as with chromate, interesting and potentially beneficial interactions of ICPs with active metal alloys are reviewed in this paper.

The study on liquid aromatic amine-aldehyde condensates as curing agent for epoxy adhesive / Madhu Bajpai in PAINTINDIA, Vol. LVI, N° 5 (05/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 5 (05/2006) . - p. 79-82 Titre : The study on liquid aromatic amine-aldehyde condensates as curing agent for epoxy adhesive Type de document : texte imprimé Auteurs : Madhu Bajpai, Auteur ; Vipin Shukla, Auteur ; Firdous Habib, Auteur ; Pragya Bajpai, Auteur Année de publication : 2006 Article en page(s) : p. 79-82 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : Aniline-formaldehyde resins may be consideredas aromatic polyamines, analogues to aliphatic polyamine curing agents. Aniline-Formaldehyde resins are synthesized by reaction of aniline and formaldehyde in strongly acidic medium. They provide superior solvent, heat and chemical resistance to those obtained with aliphatic polyamines. This hardener also provide improved electrical properties which are virtually independent of temperature upto 200°C. Note de contenu : Introduction Materials Methods - Synthesis of aniline-formaldehyde resin - Modification of aniline-formaldehyde resin - Determination of aniline value - Application of coating compositions based on different epoxy resin grades and modified aniline-formaldehyde (AF) resin Result and discussion - Evaluation of physical and chemical properties - Tack free time/post curing - Adhesion - Flexibility - Scratch hardness - Acid/Alkali resistance - Xylene resistance - Acetone resistance - Ethanol resistance - Water immersion test Conclusion Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11560 [article]

UV or not UV in screen printing inks / Bill Stephens in PAINTINDIA, Vol. LVI, N° 5 (05/2006)

[article]  inPAINTINDIA > Vol. LVI, N° 5 (05/2006) . - p. 97-100 Titre : UV or not UV in screen printing inks Type de document : texte imprimé Auteurs : Bill Stephens, Auteur Année de publication : 2006 Article en page(s) : p. 97-100 Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : In recent years probably no area of screenprinting has developed faster than UV printing. As a commercially viable technology its history is barely three decades old, but today it competes readily with the solvent-based screenprinting inks Note de contenu : What is UV printing exactly? How UV inks work UV on the Production Line What kind of printing operation could benefit from a switch to UV inks? What are the advantages of using UV? What are the disadvantages? Getting set up for UV printing Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11562 [article]
