Application
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
Bright color, high color saturation, high color strength and high gloss;
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 heat stability;
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
Durability, light and weather fastness;
High hiding power or specific transparency, high tinting power and gloss;
It has good matching and easy dispersing performance in different types of colorants;
Chemical resistance, acid and alkali resistance;
Good storage stability, without delamination or precipitation;
Excellent heat stability;
In some areas, pigments containing harmful metals are restricted or prohibited.
