Main uses and characteristics:
Ranbar yellow P3090 isoindolinone yellow organic pigment, pigment yellow 109, this pigment gives a pure green yellow, mainly used for coloring paints, plastics and printing inks, used in the coating industry for high-end industrial paint coloring , Such as automotive coatings (OEM). It is especially suitable for color matching with inorganic pigments to give a very deep color.
Runba P3090 Pigment Yellow has excellent light fastness, the natural color (5%) has a light fastness of 6~7, and it is diluted with titanium dioxide (1:3; 1:25) with a light fastness of 7~8.
The pigment has excellent resistance to overcoatings and excellent thermal stability, which can meet various requirements. The heat resistance of the alkyd melamine system is 200 ℃, and it is suitable for the coloring of architectural coatings and latex paints. Used for polyolefin coloring (1/3 SD), 1% TiO₂) heat resistance up to 300℃; 1/25 SD heat resistance 250℃, but dimensional deformation; migration resistance, heat resistance and stability in soft PVC Excellent; used for coloring polystyrene, rubber, polyurethane foam and polypropylene fiber; can also be used for high-end printing inks.
