QuinacridoneLes pigments de quinacridone sont des pigments organiques de synthèses qui vont du rouge-orange au rouge-violet.
Ils sont utilisés depuis les années 1960 par les teinturiers et les fabricants de pigment set couleurs à peindre (et plus récemment par certains tatoueurs, comme pigment dans des encres de tatouage, avec un risque allergique).
Il s'agit de pigments très transparents, au fort pouvoir colorant mais modérément couvrants.
Leur transparence permet de varier les teintes selon la densité et l'épaisseur de l'application.

Succinique, AcideL'acide succinique est un diacide carboxylique aliphatique, dénommé également acide butane-1,4-dioïque et de formule semi-développée HOOC–CH2–CH2–COOH.
Il est présent dans tous les organismes vivants et intervient dans le métabolisme cellulaire, en particulier dans le métabolisme des lipides entre l'acide cétoglutarique et l'acide fumarique lors du cycle de Krebs dans la mitochondrie.Index. décimale : 667.9 Revêtements et enduits Résumé : The culture of using biobased material is growing exponentially. Biobased raw materials consumption seems to be an emerging trend in various fields such as coating, resin, paint, pigment industries. Succinic acid is a major raw material in the coatings industry as it is used for synthesis of polymers and also in pigments. Traditional fossil based raw material (succinic acid) in coatings and paint industries seems to be limited mainly due its availability and higher cost. A steadily growing knowledge base has demonstrated that bio-succinic acid can replace traditional oil-based raw materials and even improve their performance. Biobased succinic acid is an important renewable material which acts as replacement of petroleum raw materials used for synthesis of alkyd, UV curables acrylates, powder coating, polyols, polyurethane resins and pigments. Due to limited fossil resources and an increased need for environmentally friendly, sustainable technologies, the importance of using renewable feedstocks in the paint and coatings area will increase in the decades to come. Herein, this review article describes about the biobased succinic acid as a starting material in various products. This paper highlights some of the perspectives in this area.

GraphèneLe graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié). Record en conduction thermique jusqu'à 5300 W.m-1.K-1. C'est aussi un matériaux conducteur.

Sulfate de baryumIndex. décimale : 667.9 Revêtements et enduits Résumé : Polyurethane (PU) is the most common versatile and researched material in the world. It is widely used in many applications such as medical, automotive and industrial fields. It can be foundin products such as furniture, coatings, adhesives, construction materials, paints, elastomers, insulators, elastic fibers, foams, integral skins, etc. because it has extraordinary which are available. Though the material is having fascinating properties the material is also associated with various problems such as inferior coating properties. Inorganic pigments and fillers are dispersed in organic components and binders to coating systems. It gives general introduction about the various fillers and it's classification, mechanism by which the filler enhances the mechanical properties of the materials, various factors which affects the properties of the coatings. Various methods of incorporaton of fillers in the coating systems are discussed. Various nano fillers such as SiO2, TiO2, AL2O3, antimony doped tin oxide (ATO), BaSO4, FE2O3 as well as carbon nanotubes, graphene derived fillers and nano diamonds are discussed in detail. The importance and effect of surface modification of fillers to enhance coating properties is also discussed along with challenges associated with challenges associated with polyurethane coatings and future trends.

I will give illustrative manufacturing procedure for 100 kg paint i.e. roughly 100 ltrs by using batch type sand mill which is popularly used in MSME paint units and in laboratory/pilot batches in organised sector. Usually system followed is 100kg % formula and then it is multiplied by factor of batch required. For eg. 1000 kg = 10 factor and so on. Only difference in case of continuous vertical or horizontal sand mills. Premix procedure is followed i.e part I.
