Langues : Américain (ame) Catégories : Acide polyacrylique Aminoplastes Cloquage (défauts) Couche de base Déshydratation Epoxydes Mélamine La mélamine, de nom chimique 1,3,5-triazine-2,4,6-triamine, est parfois dénommée cyanuramide ou cyanurotriamine. Sa formule brute est C3H6N6. Les "résines mélamine-formaldéhyde" ou "mélamine-formol" (sigle MF) sont appelées "mélamine" dans le langage courant. Elles font partie de la famille des aminoplastes qui regroupe des résines thermodurcissables aminées, issues d'un comonomère tel l'urée ou la mélamine, parfois le thiocarbamide, le cyanamide hydrogène ou le dicyandiamide ; le second comonomère étant le formaldéhyde. Plan d'expérience Polyacryliques Revêtements en phase aqueuse Vernis Index. décimale : 667.9 Revêtements et enduits Résumé : This research investigated popping when automotive clearcoat was applied over waterborne basecoats using design of experiments (DOE). The study was conducted using melamine crosslinked acrylic latex basecoat and acrylic acid/epoxy clearcoat. The focus of the project was directed toward the paint application and dehydration stages. The study was conducted in four phases. In Phase 1, three paint application parameters, flow rate (FR), atomizing air (AA), and distance of the applicator tip from the substrate (D), were investigated. In Phase 2, FR and target distance were investigated in relation to popping while keeping other parameters as well as film build constant. In Phase 3, the effect of film build on popping was investigated by selecting three levels of film build. Phase 4 was focused on the possible effect of dehydration oven temperature on popping. Results indicated that FR does not affect popping directly. However, it significantly affects the film build. Both film build and dehydration oven temperature were found significant in relation to popping occurrences. This work suggests that dehydration oven temperature and film build affect solvent popping. Although this study identified the significant factors causing waterborne basecoat popping, conditions for a pop-free paint surface were not established.
