Coil coatings
MélamineLa 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.

| Résumé : |
End customers' decisions are ultimately determined by quality and high demand for excellent visual appearance. The new surface additives improve processing and visuel appearance significantly. In solvent-based can and coil coatings, such specially developed polyacrylates provide excellent appearance. The products' composition and their far-reaching listings and registration leads to universal application. Recoatability is excellent, due to the fact that they do not impair the surface energy of cured films. Both new additives fulfill 21 CFR FDA regulations 175.300 and all components are listed in Annex 6 in the lists for evaluated (A) or not evaluated (B) substances according to Swiss Ordinance (SR 817.023.21).
- The new flow additive shows a broad compatibility with all binders and high optical transparency.
- The new flow additive provides flow improvement as well as an additional deaerating effect.
- Both products are free of hazardous ingredients like BPA, aromatics and halogens.
The excellent optical appearance attracts can and coil coating customers worldwide |
