Titre : Synthesis of polymeric dispersants from renewable DCO fatty acid and their multifunctional behavior in waterborne flat paint Type de document : texte imprimé Auteurs : Ravi Dara, Auteur ; Ghanshyam Jaiswal, Auteur ; Girish Mirchandani, Auteur ; Randhir Parmar, Auteur ; Syed Haseebuddin, Auteur ; Gulzar Waghoo, Auteur ; Kumar Ghosh Swapan, Auteur Année de publication : 2009 Article en page(s) : p. 493-499 Note générale : Bibliogr. Langues : Américain (ame) Tags : Dehydrated castor oil fatty acids (DCOFA) Maleic anhydride Polymeric-dispersant Pigment dispersant Rheology modifier Zeta potential Minimum film-forming temperature (MFFT) Waterborne flat paint Index. décimale : 667.9 Revêtements et enduits Résumé : Copolymers containing 50% dehydrated castor oil fatty acids (DCOFA) derived from renewable resources, were synthesized via free radical solvents less polymerization with maleic anhydride, styrene, and butyl acrylate. The copolymer was crosslinked further with polyethylene glycol 400 (PEG 400) to increase its molecular weight. The copolymers with and without crosslinking were then neutralized with sodium hydroxide to prepare polymeric dispersants DFCD1 and DFCD2 respectively in aqueous medium. It was observed via surface-tension measurement that both DFCD1 and DFCD2 transfer to the air–water interface before forming any aggregates, and the ease of forming the aggregates is in the order of DFCD1 > DFCD2. The efficacy of these dispersants was examined in the dispersion of the titanium dioxide pigment and conventional extenders like calcite, talc, and china clay using flow point and zeta potential measurements. The results reveal that DFCD2 improved the dispersing ability for the pigment and extenders studied. The performance of these polymeric dispersants was also studied and compared in waterborne flat paint as a rheology modifier and pigment-dispersing agent. The paint rheology profile and dE data indicate the superior performance of the paint containing dispersant DFCD2. When used in combination with conventional styrene-acrylic latex, DFCD1 and DFCD2 reduced the minimum film-forming temperature (MFFT) of the polymer latex.

Tests with a gloss paint containing different grades of titanium dioxide showed that HALS had by far the greatest effect with the most durable grades, while the type of HALSused was less significant.

Double cylindrical annular gap mills, in contrast, can be scaled up linearly. The high power density in the small-volume mills of this type can lead to a marked increase in the product quality. The high productivity obtained from a small grinding chamber contributes to reducing operating costs and hence to increasing the efficiency of the production process.

Titre : Multifunctional additive : Improving dispersion efficiency Type de document : texte imprimé Auteurs : Simon Poulton, Auteur Année de publication : 2001 Article en page(s) : p. 26-27 Langues : Anglais (eng) Tags : Paint Manufacturing Adjuvant Dispersant 'Grinding(comminution)' Dispersion Formulation Index. décimale : 667.9 Revêtements et enduits Résumé : A performance additive with a number of features that offer significant benefits to formulators of waterborne systems is welcome. The base strength of Bisomer Amine D 700, 77% aqueous dimethylaminohydroxypropane (DMAHP), enables effective pH adjustment and neutralisation whilst the volatile nature Improves early water resistance, gloss, and scrub resistance. Also when used in an optimised formulation, it is shown In this paper that DMAHP can reduce primary dispersant levels and hence reduce formulation costs. In addition, the tertiary amine structure enhances biocide efficiency. Note de contenu : - Experiment : dispersant demand procedure
