This article compares the properties of acrylic and acrylic/styrene dispersions when used as binders in such paints. The films formed from these dispersions absorb little water. Acrylic/styrene films are more permeable to water vapour than straight acrylic ones. There is no difference in the performance of acrylic and acrylic/styrene latices in mat paints formulated for use outdoors.

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. Note de contenu : - Raw materials used - Results of the tests - Hydrophobic binder supports film formation at 5°C - Solvent-free paints absorbs more water then solvent-containing - Colour change due to artificial weathering - Chalking results depends on binder type En ligne : https://drive.google.com/file/d/13bkhSDxb7fQuXXW1toekxSXnpAMcER38/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=10936 [article]

Acrylic latex paints / Roland Baumstark in EUROPEAN COATINGS JOURNAL (ECJ), N° 5/01 (05/2001)  

[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]

Acrylic latex paints : a comparison study (part I) / Manfred Schwartz in EUROPEAN COATINGS JOURNAL (ECJ), N° 03/01 (03/2001)

A suitable binder is necessary to give a high quality paint. Experiments on masonry paints in the PVC range of 35 to 55% show that after many years of outdoor exposure no significant difference between straight acrylic and acrylic/styrene copolymers can be found. More important is the optimisation of the pigment volume concentration and the pigment/extender combination than the type of the binder.

Langues : Anglais (eng) Catégories : Polyacryliques Revêtements:Peinture Index. décimale : 667.9 Revêtements et enduits Résumé : Acrylic polymers are essentiel products for various industrial application fields. Particularly, they play important roles as binders (acrylic resins), dispersion resins and polymer thickeners in the coatings industry. Since acrylic resins were launched onto the coatings market, they have distinguished themselves by meeting various quality requirements and replacing other resins. Acrylic resins are used in eco-friendly coating systems, for example. Thanks to their broad range of properties and to ongoing developments within this product class, they also serve as ingredients for different coating systems. The present book presents an overview of the production, properties and application of acrylic resins and their distinctive features. It covers acrylic resins prepared by solution polymerization and emulsion polymerization, as well as reactive acrylic resins which form films by radiation curing. Besides a general description of these three product classes, there are chapters dealing with particular properties for the diverse application fields. The goal of the book is to convey the latest knowledge about acrylic resins in solvent-borne and water-borne systems, and for radiation curing in an understandable and descriptive manner. Given the breadth of applications for acrylic resins, the book discusses the different chemical and physical aspects of the production methods and the related application properties. There are numerous literature citations for further reading on specific issues. The book is aimed at students and newcomers to the field of coatings technology, and also at well-versed experts in coatings applications and other related industries. The essential background information herein will underpin decisions concerning the choice and use of acrylic resins. Note de contenu : - General composition and structure - Solution polymerization products - Primary dispersions of acrylic resins - Acrylate resins for radiation curable coatings Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=16676
