Our pigments have a wide variety, bright colors and high color strength. They are widely used in ink printing, paint/coatings, plastics and rubber and other industrial fields, and become indispensable coloring materials for the production of a variety of industrial products.
Ink
In four-color printing, the yellow pigment should have excellent transparency to meet the quality requirements of color reduction;
Good ink printing adaptability, such as the fluidity and thixotropy of colored ink;
Solvent ink pigmented organic pigments should have good solvent resistance, do not change color, do not increase the viscosity of the colored ink;
In some areas, pigments containing harmful metals are restricted or prohibited.
Plastic
Excellent migration resistance, no frosting phenomenon;
It has good compatibility and easy dispersibility with resin;
The organic pigments used for coloring plastic products for outdoor use should have excellent light fastness and weather fastness;
Coloring plastics for food packaging and toys, strictly limit the content of harmful heavy metals in them.
Paint
High hiding power or specific transparency, high tinting power and gloss;
Good storage stability, without delamination or precipitation;
Organic Pigments Technology R & D Center develops new varieties and dosage forms of pigments to satisfy the needs of customers and provide customers with technical support,it is equipped many intruments to test relative data,such as: particle size and distribution of pigments;pigments micro shape,appearance and crystal line;pigments appearance property; color measuring,easy dispersible evaluation,dispersion stability,the specific surface area; MS testing banned from use arylamine.
