Controlled coagulation of emulsion polymers / Edward Kostansek in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 1, N° 1 (01/2004)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 1, N° 1 (01/2004) . - p. 41-44 Titre : Controlled coagulation of emulsion polymers Type de document : texte imprimé Auteurs : Edward Kostansek, Auteur Année de publication : 2004 Article en page(s) : p. 41-44 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Coagulation Colloides Copolymères en émulsion Copolymérisation Latex Polyacrylate de butyle Polyaddition Polyméthacrylate de méthyle Le poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec. Poudres Index. décimale : 667.9 Revêtements et enduits Résumé : Coagulation of latex particles is most often carried out in the diffusion limited aggregation (DLA) regime where the time for coagulation to take place is on the millisecond timescale. This process produces aggregates of low density, irregular shape, and a broad particle size distribution. When the coagulation is carried out in the reaction limited aggregation (RLA) regime, a coagulation time of about 1-120 sec, the system can be controlled by mixing to yield dense, spheroidal aggregates with a very narrow particle size distribution. The important variables in the RLA process for butyl acrylate/methyl methacrylate (BA/MMA) latexes were found to be mixing intensity, latex copolymer composition, and coagulation temperature. Dried aggregates formed in the RLA process were found to have excellent powder flow properties and low dustiness.

Enhancement of the Mie scattering effect using floatstone-like TiO2 spherical micropigment / Tomohiro Shirosaki in COLORATION TECHNOLOGY, Vol. 133, N° 3 (06/2017)

Langues : Anglais (eng) Catégories : Acide polyacrylique Core-Shell Dioxyde de titane Particules (matières) Pigments inorganiques Polyacrylate de butyle Polyacrylates Réflectance Index. décimale : 667.3 Teinture et impression des tissus Résumé : Floatstone-like TiO2 microparticles with an efficiently enhanced Mie scattering effect were developed by thermofusing of rutile-type TiO2 submicron particles on the template core of poly(acrylate) microspheres. The light reflectance of the floatstone-like TiO2 microparticles was approximately 10% higher than that of the usual rutile-type TiO2 submicron particles in a wavelength range from 400 to 850 nm. The diffuse reflectance of the microparticles is enhanced by the formation of a floatstone-like structure, whereas there is no difference in the specular reflectance of the particles. As an application of the floatstone-like TiO2 microparticles, the contribution of the particles to the light-trapping effect of a solar cell was examined. The power conversion efficiency of the solar cell was enhanced by 22% with the introduction of a light-scattering layer composed of the floatstone-like TiO2 microparticles.

Film formation of vinyl acrylic latexes ; effects of surfactant type, water and latex particle size / Gerald A. Vandezande in JOURNAL OF COATINGS TECHNOLOGY (JCT), Vol. 68, N° 860 (09/1996)

Water plasticizes this polymer and thus only wet viscoelastic parameters and Tg values are realistic in film formation theories. The polymer is plasticized by ethoxylated alkylphenol nonionic surfactants. The surfactants with shorter ethylene oxide chains are better plasticizers and poorer steric stabilizers than their longer analogs. The type and concentration of stabilizing entities on the latex particle surfaces have very significant effects on the drying and coalescence properties of these latexes. Coalescence is somewhat faster with smaller latex particle sizes but larger particle size products dry at a faster rate than smaller ones in the absence of surfactant effects.

Fluorinated additives for stain-resistant matt latex paints / J. Branquinho in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 6, N° 4 (12/2009)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 6, N° 4 (12/2009) . - p. 483-491 Titre : Fluorinated additives for stain-resistant matt latex paints Type de document : texte imprimé Auteurs : J. Branquinho, Auteur ; J. A. C. Alves, Auteur ; Susana Carvalho, Auteur ; Jorge Moniz, Auteur ; Fernanda Oliveira, Auteur ; M. H. Gil, Auteur Année de publication : 2009 Article en page(s) : p. 483-491 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Fluoropolymères Latex Polyacrylate de butyle Résistance aux taches Revêtements en phase aqueuse -- Additifs:Peinture en phase aqueuse -- Additifs Index. décimale : 667.9 Revêtements et enduits Résumé : Latex paints are often preferred over solvent-based paints due to their good gloss and color retention, ease of handling, and lower volatile organic contents. However, matt latex paints tend to show poor stain resistance since they develop highly porous and rough surfaces. In recent years, matt latex paints have been improved in their stain resistance with resulting better cleanability, by adding hydrocarbon acrylic polymers and fluorine-containing compounds. In this work, we prepared fluorinated acrylic emulsions of the copolymer of butyl acrylate (BA) and perfluorobutylethylene (PFBE), which were introduced in latex paint compositions. The properties of the modified paints were evaluated by performing stain resistance tests with several domestic products. It was observed that they had good stain release properties, thus conferring good properties to the final painting system. They contain the self-cleaning behavior typical of fluorinated coatings, which have been proven by the decrease of their surface energies. Since the cleaning procedures of a matt paint film can also impart some gloss increase, the wet and dry burnishes were also evaluated. The results have shown improvements in stain resistance and cleanability of the modified matt latex paints with the maintenance of their stability and the coatings gloss as required.
