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.

Revêtements -- DétériorationIndex. décimale : 667.9 Revêtements et enduits Résumé : A series of coil coatings based on a polyester/melamine resin formulation, incorporating different pigment systems, were naturally weathered after being exposed to the elements in Hainan, PRC, for 2 years. The surface chemistry and morphology, before and after weathering, was investigated using both traditional (i.e., gloss retention, color change) and novel (i.e., X-ray photoelectron spectroscopy [XPS], atomic force microscopy [AFM], and scanning electron microscopy [SEM]) methods. Chemical changes occurring in the coating bulk were investigated using step-scan photoacoustic Fourier transform infrared spectroscopy (SSPA-FTIR). It was found that the coating surface morphology, surface chemistry, and bulk chemistry, both before and after weathering, were all affected by the type and concentration of the pigments included in the coating formulation. Moreover, it was found that different types of pigment catalyze different coating degradation mechanisms.

Pigments organiquesIndex. décimale : 667.2 Colorants et pigments Résumé : The paint industry in the country performs a very vital rote in the protection of national assets from corrosion. Organic surface coatings are the cheapest and most convenient mode of protection of metals and non-metals from corrosion. Pigments are the integral part of surface coatings special ly when used for corrosion protection. There are pigments which are specially meant for th is very purpose and are known as anti corrosive pigments. Anti-corrosive pigments inhibit corrosion process either chemically and/or electrochemically (Active Pigments) and/or physically (Barrier Pigments) and may be divided by the way they work.

LaccasesLes laccases (EC 1.10.3.2) appartiennent à une famille d'enzymes ayant pour cofacteur du cuivre. C'est une oxydase (oxydoréductase, EC 1) que l'on retrouve dans de nombreuses plantes, champignons et micro-organismes.
Le cuivre est lié sur plusieurs sites de la protéine. On distingue trois types. Les types 2 et 3 sont appelés grappe tri-nucléaire. Le cuivre du type 1 est soluble dans l'eau. Le mercure déplace le cobalt complexé dans les laccases. Les complexants du cuivre peuvent le déplacer et le remplacer par du cobalt. Les cyanures complexent également le cuivre, mais dans ce cas il n'est pas possible de réinsérer du cobalt.
Les laccases oxydent les dérivés phénoliques mais d'une façon ménagée qui transforme la lignine en monolignol.

Stabilité hydrothermaleIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : An alternative to the normal dyeing route to achieving colour in leather is to exploit the chemistry of creating the natural skin and hair pigments, melanins. 1,8-dihydroxynaphthalene and other dihydroxynaphthalenes can be oxidised and polymerised to create pigment products by reactions catalysed by laccase, a polyphenol oxidase.
They not only create colour, but, if the reactions are conducted in the presence of collagen, the pigments are bound to the collagen by covalent bonds, which confer a tanning effect.Note de contenu : - EXPERIMENTAL PROCEDURES : Materials - Dyeing experiments - Measurements of colour - Measurement of hydrothermal stability

TétraphényléthylèneIndex. décimale : 667.2 Colorants et pigments Résumé : Three novel tetraphenylethene–organophosphorus dyads – (6-oxido-6H-dibenz[c,e][1,2]oxaphosphorin-6-yl)[4-(1,2,2-triphenylvinyl)phenyl] methanol, diphenyl {hydroxy[4-(1,2,2-triphenylvinyl)phenyl]methyl} phosphine oxide, and di(3,5-dimethylphenyl){hydroxy[4-(1,2,2-triphenylvinyl)phenyl] methyl} phosphine oxide – were synthesised and characterised by 1H, 13C, and 31P nuclear magnetic resonance spectroscopy, mass spectrometry, and elemental analysis. The photoluminescence properties were studied. All three dyads exhibited intense solid-state blue emission peaking at 449–466 nm, and also displayed aggregation-induced emission behaviours. The emission decays of these dyads in the solid state also fitted well with a triexponential model with an average lifetime of 2.65–4.42 ns. The experimental results demonstrated that the luminescent properties are highly dependent on the nature of the organophosphorus groups. The choice of phosphorus-containing components can cause variations in the photoluminescence emission and photoluminescence decays.

Pigments organiquesIndex. décimale : 667.2 Colorants et pigments Résumé : In the previous chapter we saw the historical information regarding Pigments and how it came into existence and used in Paints. Now let's see the classifications of Pigments.
It is not sufficient for the artist to learn merely the general outline rules about pigments or to be familiar with them. Because of the wide variation in their individual behaviours and properties, each one must be noted by itself, and its relative position in the general classification must be learned. The most satisfactory way to classify a pigment is according to its source, because most of the significant properties which any pigment groups may have in common can be attributed to their composition. All point pigments are manufactured products ; regardless of whether they are obtained from natural or artificial sources, they will never be satisfactory unless they have been carefully prepared by expert methods.Note de contenu : - Native earths
