颜料蓝 15:1（星辉蓝 15:1）

产品概览

Pigment Blue 15:1 is an organic pigment belonging to the phthalocyanine family. It represents the stabilized α (alpha) crystal form of copper phthalocyanine, featuring a reddish-blue hue with excellent color strength, outstanding heat resistance, and excellent light fastness. The stabilized α form offers crystal stability in solvent-based systems, making it suitable for a broader range of applications than the unstable α form (PB15:0).

How to Interpret These Specifications

• Light Fastness (7–8): Excellent to outstanding. One of the highest light fastness ratings among organic pigments.
• Heat Resistance (≥250°C): Outstanding. Suitable for high-temperature processing conditions.
• Weather Fastness (7–8)出色。经多年户外暴露，颜色依然保持鲜艳。
• Crystal Stability (Stabilized α): The stabilized α form resists crystal transformation in solvent-based systems, making it suitable for aromatic solvent-based inks and coatings where the unstable α form (PB15:0) would transform.

关键应用领域

1. 印刷油墨

• Solvent-Based Offset Inks: Preferred for solvent-based offset ink systems where crystal stability is required.
• Gravure Inks: Suitable for gravure printing with aromatic solvent systems.
• Flexographic Inks: Compatible with solvent-based flexo ink formulations.
• Water-Based Inks: Also suitable for water-based systems.

2. 涂层

• Solvent-Based Coatings: The stabilized α form is preferred for solvent-based coating systems.
• Industrial Finishes: Compatible with industrial paint formulations.
• 汽车涂料: Used in automotive coating systems requiring a reddish-blue shade.

3. Plastics

Suitable for coloring various plastics including PE, PP, PVC, PS, and engineering plastics. The stabilized α form offers better crystal stability during polymer processing.

重要提示：

• 颜料蓝 15:1 是stabilized α (alpha) crystal form of Phthalocyanine Blue, featuring a 红蓝色调.
• The stabilized α form resists crystal transformation in solvent-based systems, making it more versatile than PB15:0.
• For applications requiring a greenish-blue shade, consider PB15:3 (β form).

Packaging & Storage

• Packaging：25kg/bag，带内衬 PE 层。可按需提供定制包装。
• Storage存放于阴凉、干燥且通风良好的地方，避免阳光直射和热源。防止受潮——不使用时请保持袋口密封。保质期：在适当储存条件下，自生产之日起 24 个月。
• Transportation：不属于联合国运输规章规定的危险品。请小心搬运，避免行李破损。

Frequently Asked Questions (FAQ)

What is Pigment Blue 15:1?

Pigment Blue 15:1 (PB15:1) is the stabilized α (alpha) crystal form of copper phthalocyanine with C.I. number 74160 and CAS number 147-14-8. It features a reddish-blue hue with excellent light fastness (Grade 7–8), outstanding heat resistance (≥250°C), and crystal stability in solvent-based systems.

What is the difference between PB15:0 and PB15:1?

Both are α (alpha) crystal form phthalocyanine blue pigments with a reddish-blue shade. The key difference is crystal stability: PB15:0 is the unstable α form that may undergo crystal transformation in aromatic solvent-based systems, while PB15:1 is the stabilized α form that resists such transformation. PB15:1 is more versatile and suitable for a broader range of applications.

When should I choose PB15:1 over PB15:3?

Choose PB15:1 when you need a 红蓝色调. Choose PB15:3 when you need a greenish-blue shade. Both offer excellent performance; the choice depends on your color requirements.
