[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 5/01 (05/2001) . - p. 50-65 Titre : Acrylic latex paints Titre original : a comparative study (Part II) Type de document : texte imprimé Auteurs : Roland Baumstark, Auteur ; Carlos Costa, Auteur ; Manfred Schwartz, Auteur Année de publication : 2001 Article en page(s) : p. 50-65 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Dispersions et suspensions Latex Liants Polyacryliques Revêtements organiques Index. décimale : 667.9 Revêtements et enduits Résumé : In earlier work two commercially available aqueous dispersions were used to demonstrate the suitability and differences of acrylic/styrene (Ak/S) and pure acrylic (Ak) copolymers as binders for masonry paints. With the help of a variety of model dispersions, the current work continues to look at the two binder types by studying how chemically different monomers affect the film properties and those of formulated paints. Note de contenu : - MODEL DISPERSIONS WITH TYPICAL BINDER MONOMERS - RESULTS OF TESTS ON THE POLYMER DISPERSION FILMS : Good water solubility of monomer causes high water uptake of the polymer film - High Water-vapour transmission rate relates to hydrophilic polymer - Repeated washing and drying influences the tensile strenght - n-butylacrylate copolymers exhibits the greatest photostability, styrene lowers the photostability - High styrene content efectuate yellowing of the pure binder during artificial weathering - Results of natural weathering are contradictive to the accelerated artificial weathering tests - RESULTS OF TESTS ON PIGMENTED COATING : Water absorption, WVTR's and tensile strengths of the pigmented paints - WEATHERING OF THE PAINF FILMS : Artificial weathering shows differences in the chalking behaviour but not concerning yellowing - Dirt pick-up-resistance is enhanced by binders'Tg and hydrophobicity - Interpretation of the study results En ligne : https://drive.google.com/file/d/1lADJoXg6Oo26qZOwU2bHfLKc0Fd7lXuf/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10957 [article]

Comparative studies of acrylic latex paint (Part 1) / Roland Baumstark in EUROPEAN COATINGS JOURNAL (ECJ), N° 5/99 (05/1999)  

[article]  inEUROPEAN COATINGS JOURNAL (ECJ) > N° 5/99 (05/1999) . - p. 44-48 Titre : Comparative studies of acrylic latex paint (Part 1) Type de document : texte imprimé Auteurs : Roland Baumstark, Auteur ; Carlos Costa, Auteur ; Manfred Schwartz, Auteur Année de publication : 1999 Article en page(s) : p. 44-48 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Copolymère styrène acrylique Décoloration Latex Liants Photostabilité Polyacryliques Revêtements -- Propriétés mécaniques:Peinture -- Propriétés mécaniques Revêtements organiques Index. décimale : 667.9 Revêtements et enduits Résumé : Latex paints formulated with two typical commercial acrylic dispersion binders - one a pure acrylic (Ak), the other an acrylic/styrene (Ak/S) were investigated. This included determination of the films mechanical properties, colour change (when subjected to artificial weathering), resistance to water and water-vapour transmission rates. Our investigations revealed there to be little difference between the two types of polymer in the 15-55% Pigment Volume Concentration (PVC) range. As earlier work showed, an optimum PVC and the right combination of pigment and extender are more important than the type of binder. Note de contenu : - Investigation of two typical commercial acrylic dispersion binders - Test methods and mechanical testing (tensile strength/elongation at break) on the films - Testing discoloration - Interaction between the pigment and binder depends on the amount of absorbed water - The water absorption drops with the number of wash/dry cycles - Water-vapour transmission rate decrease with PVC - Two opposing effects influence tensile properties - Water toughens and improves the extensibility of Ak/S paint films more than Ak paint films - Pure acrylic paints exhibit superior light stability than acrylic/styrene ones - Practically no yellowing - Summary of results En ligne : https://drive.google.com/file/d/19IoJJcFdvbawZwAn_7mIWWDgOMNPh_7F/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11188 [article]

Comparative studies of acrylic paints / Roland Baumstark in SURFACE COATINGS INTERNATIONAL. PART A : COATINGS JOURNAL, Vol 87, A05 (06/2004)

Langues : Anglais (eng) Catégories : Copolymères Essais accélérés (technologie) Etudes comparatives Humidité -- Absorption:Eau -- Absorption Polyacryliques Revêtements -- Propriétés mécaniques:Peinture -- Propriétés mécaniques Index. décimale : 667.9 Revêtements et enduits Résumé : To protect a building, the applied masonry paint must have good water resistance, a good water vapour tranmission rate (WVTR) and good weatherability. Futhermore, good dirt pickup resistance, colour maintenance, low chalking and good elasticity of the coating are required a long-pasting paint. All these properties of the coating are influenced by the choice of the binder. By copolymerising different monomers, it is possible ti vary the properties of the binders over an extremely wide range.

Preferred partitioning : the influence of coalescents on the build-up of mechanical properties in acrylic core–shell particles (I) / Bas Lohmeijer in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 9, N° 4 (07/2012)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 9, N° 4 (07/2012) . - p. 399-409 Titre : Preferred partitioning : the influence of coalescents on the build-up of mechanical properties in acrylic core–shell particles (I) Type de document : texte imprimé Auteurs : Bas Lohmeijer, Auteur ; Roelof Balk, Auteur ; Roland Baumstark, Auteur Année de publication : 2012 Article en page(s) : p. 399-409 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Analyse mécanique dynamique Bois -- Revêtements Coalescence (Sciences physiques) Core-Shell Couches minces Liants Polyacryliques Polymérisation en émulsion Index. décimale : 667.9 Revêtements et enduits Résumé : The partitioning of three coalescents of different polarity in different phases of multiphase acrylic particles was studied to provide a rationale for obtaining the desired performance of binders for wood coatings in terms of the ideal balance between hardness development, blocking resistance, and blushing resistance. Minimum film formation temperature- and aqueous differential scanning calorimetry-measurements on the hard phase polymer by itself showed the different extents to which both hydroplasticization and plasticization by the coalescent occur. Dynamic mechanical thermal analysis was subsequently used to visualize wet-T g effects of three different coalescents in the hard and soft polymer phase of these multiphase acrylic particles. The results have important consequences for the formulation of such binders in applications for exterior wood coatings and coatings in general.
