Langues : Américain (ame) Catégories : Applications extérieures Latex Revêtement mural:Peinture murale Revêtements -- Défauts:Peinture -- Défauts Index. décimale : 667.9 Revêtements et enduits Résumé : Flooding and floating are problems in many paint applications. If pigment concentration is uniform on the surface but not through the thickness of the film, one refers to 'flooding' (horizontal separation). If, however, concentration differences are visible across the surface of the paint film, one refers to 'floating' (vertical separation). In this article, the influence of pigment, filler, additives, and processing conditions on the flooding and floating of colored latex paint were investigated. It was discovered that too broad a distribution of pigment and filler particle size can lead to flooding and floating. Different levels of pigment (TiO2) or filler (kaolin) loading cause diverse degrees of flooding and floating. Waterborne coatings that do not exhibit flooding or floating may show these conditions when diluted. Using dispersants or thickeners with hydrophobic constituents, increasing viscosity, reducing surface tension, etc., all help to prevent or reduce flooding and floating. Comparison tests revealed little influence of processing conditions on flooding or floating.

Synthesis and characterization of fluorine-containing poly-styrene-acrylate latex with core–shell structure using a reactive surfactant / Guilong Xu in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 8, N° 3 (05/2011)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 8, N° 3 (05/2011) . - p. 401-407 Titre : Synthesis and characterization of fluorine-containing poly-styrene-acrylate latex with core–shell structure using a reactive surfactant Type de document : texte imprimé Auteurs : Guilong Xu, Auteur ; Lili Deng, Auteur ; Wen Xiufang, Auteur ; Pi Pihui, Auteur ; Dafeng Zheng, Auteur ; Jiang Cheng, Auteur ; Yang Zhuoru, Auteur Année de publication : 2011 Article en page(s) : p. 401-407 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Caractérisation Copolymère styrène acrylique Core-Shell Fluorine Latex Surfactants réactifs Index. décimale : 667.9 Revêtements et enduits Résumé : Fluorine-containing poly-styrene-acrylate (PSA) latex with core–shell structure was successfully synthesized by seeded semicontinuous emulsion polymerization using fluorine monomer Actyflon-G04 and reactive emulsifier DNS-86. The chemical composition, morphology of latex, and surface composition of the latex film were characterized by Fourier transform infrared spectra, transmission electron microscopy, and X-ray photoelectron spectroscopy, respectively. The stability properties of latex were tested by Ca2+, centrifugal and mechanical stability tests, and the latex film was studied by water contact angle, water absorption ratio, and thermo-gravimetric analysis. The results show that fluorine-containing PSA latex particles with crosslinked core and crosslinked shell structure have excellent stability properties, and the film of latex has excellent water repellency, thermal stability, and chemical resistance properties when the amount of fluorine monomer was only 8.0 wt %.
