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. Ressources renouvelables Revêtements organiques Revêtements poudre:Peinture poudre Revêtements:Peinture Succinique, Acide L'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.

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.
