                      TeYuan is the Professional Manufacturer and Exporter of the Prussian Blue


Prussian blue is a blue inorganic pigment ,It is Produced by iron salt and ferrocyanide or ferricyanide, also known as Chinese blue, Prussian blue, miloli blue and pigment blue 27;


Prussian blue is a kind of powder with dark blue appearance, fine and large dispersion. Relative density 1.8. Insoluble in water, ethanol and ether, soluble in acid and alkali. The color light can be between dark blue and bright blue, with bright color, strong coloring power, strong diffusivity, large oil absorption and poor covering power. The powder is hard and hard to grind. It can resist sunlight and dilute acid, but decomposes when boiling with concentrated sulfuric acid; it has weak alkali resistance, even dilute alkali can decompose it.

It cannot be shared with alkaline pigments. When heated to 170-180 ℃, crystal water will be lost, and when heated to 200-220 ℃, hydrocyanic acid will be released by combustion. In addition to a small amount of additives which can improve the performance of pigment, fillers are not allowed.


Product performance features:

1. Excellent heat resistance, climate fastness and bright color.

2. It is insoluble in water, mineral oil and vegetable oil, without color seepage.

3. It does not affect the vulcanization process of rubber products and has reinforcement effect on products.

4. Excellent dispersion and wear resistance.

5. Stable quality, small color difference between batches.

6.Good quality in coloring strength and color uniformity. Due to its specific chemical composition and structure, the product also has good light resistance, acid and alkali resistance, weather fastness and UV stability. They are ideal for stationery, ink, cosmetics and leather coloring.

Mainly Application:

Mainly used in coating, ink, paint, coating, paint paper, carbon paper, painting pigment, crayon, etc;

Detailed application:

It can be applied to all kinds of industrial coatings and ink coloring and protective substances, including water-based interior and exterior wall coatings, decorative coatings, latex paint powder coatings, industrial coatings, wood coatings, etc.; it can also be applied to oil-based coatings, including epoxy, alkyd, amino and other primers and topcoats; it can also be used for toy paint, automobile paint, furniture paint, electrophoretic paint, enamel and printing ink, intaglio ink;

It is used for coloring PVC plastic products, such as thermosetting plastic and thermoplastic, and rubber products, such as automobile inner tube, aircraft inner tube, rubber polymer, plastic coating, plastic products, laminated materials, wood plastic composite materials, etc.

In addition, organic pigments are also suitable for coloring all kinds of stationery, cosmetics, paper and leather. In recent years, it has also played a special role in catalysis, semiconductor, electronic photography and light energy conversion


Usage and dosage (For Reference)

How many pigments are needed to color a ton of base material: in a typical industrial coating, 1.5-12kg pigments are needed per ton of material.

Water based coating: appropriate configuration according to different colors. The product has good dispersibility, stable storage, good compatibility with other components in the application system, and can enhance the antirust, UV resistance and other properties of the paint.

Reference pigment content of paint formula: primer 25-30%; ready mixed paint 20-30%; enamel 15-25% (excluding physical pigment)
