Phthalocyanine blue BGS is a β - type stable crystalline copper phthalocyanine organic pigment, a commonly used green light blue pigment in the industry, and one of the most widely used phthalocyanine blue varieties, CAS：147-14-8， Molecular formula \ (\ boldsymbol {C_ {32}H_{16}CuN_8 }\)Qingdao Sa...。

1、 Basic appearance and physical and chemical indicators

-Appearance: Dark blue with green light powder, semi transparent, rod-shaped monoclinic crystal

-Color Light: Bright Green Blue (Peacock Blue)

-Oil absorption capacity: 40-50g/100g

-Moisture content: ≤ 1.5%; 80 mesh sieve residue ≤ 5%

-PH value: 7.0-8.0

-Solubility: insoluble in water, alcohols, and hydrocarbons; Dissolve in concentrated sulfuric acid, and precipitate blue precipitate after dilution

2、 Core performance characteristics

1. With extremely high coloring power, adding a small amount can obtain a full blue color, bright and pure color

2. Excellent fastness: 7~8 grade light resistance, 240~280 ℃ heat resistance, 5 grade acid resistance, alkali resistance, oil resistance and solvent resistance, migration resistance, color penetration resistance, and color fading resistance

3. Crystal stability: β crystal form, does not undergo crystal transformation or flocculation in solvent systems, and has good storage stability

4. Good dispersibility, suitable for various processing systems such as inks, coatings, and plastics

5. Environmentally friendly products can achieve low heavy metal content and comply with environmental testing requirements such as RoHS and toy materials

Comparison: Phthalocyanine Blue B (PB15:1, alpha type red light blue); BGS (PB15:3, β - type green blue, more stable)
