How to Interpret These Specifications

• Heat Resistance (180–200°C): Good heat stability. Suitable for many ink, rubber, and plastic processing conditions. The exact upper limit depends on dwell time and the specific application system.
• Light Fastness (Full Tone 4–5 / Tint 2–3): Moderate in full tone and limited in tint. 不推荐 for exterior paint or long-term outdoor applications. PO16 is best suited for interior and short-life applications.
• Solvent Resistance: Moderate. Shows good resistance to water (grade 5) and acid (grade 5), but limited resistance to alcohol (grade 3) and xylene (grade 3). Verify compatibility with your specific solvent system.
• 吸油值（28–55 g/100g）: Typical for disazo pigments. The wide range reflects differences in binder demand depending on the application system.

关键应用领域

1. 印刷油墨

Printing inks represent the primary application for Pigment Orange 16.

• 偏移油墨: PO16 is used in offset inks, including sheetfed and web offset systems.
• 水性油墨: Suitable for water-based flexographic and gravure inks.
• Solvent-Based Inks: Used in solvent inks for packaging and specialty printing.
• Shade Adjustment: PO16 is particularly used to adjust the shades of Pigment Yellow 12 type diarylide yellow pigments, producing a wide range of orange and warm yellow tones.

2. Rubber Products

PO16 is a suitable colorant for rubber products where low-cost production and adequate lightfastness are acceptable. It is used in both dry rubber and latex applications.

3. 纺织品印花

Used in textile printing pastes and garment dyeing applications, including padding and slasher dyeing.

4. Plastics

Suitable for coloring PE, PP, PS, and PVC in selected applications. However, migration in PVC and other polymer systems should be evaluated before use.

5. Coatings (Limited)

PO16 can be used in some decorative coating applications, but its limited lightfastness and durability make it unsuitable for exterior paints or long-term outdoor exposure.

Important notes:

• 颜料橙 16 是not lightfast or durable enough to be used in exterior paint systems.
• The pigment is considerably redder than Pigment Orange 13 and Pigment Orange 34, making it a distinct shade in the orange pigment family.
• PO16 can serve as a lead-free alternative to molybdate orange in selected applications.

Packaging & Storage

• Packaging: 25kg/bag with inner PE liner
• Storage: Store in a cool, dry, ventilated area away from direct sunlight. Keep container tightly closed when not in use.

Frequently Asked Questions (FAQ)

What is the difference between Pigment Orange 16 and Pigment Orange 13?

Both are disazo pigments, but they differ in chemical class, hue, and performance:

Property	PO16	PO13
化学类别	Disazo / Dianisidine	双偶氮 / 吡唑啉酮
Hue	Yellowish orange, considerably redder	Bright reddish orange
耐光性（全）	4 – 5	5 – 7
Heat Resistance	180 – 200°C	160 – 200°C
主要用途	Inks, rubber, textile printing	Inks, coatings, plastics

PO16 is redder than PO13 and is more commonly used in rubber and textile applications. PO13 generally offers better lightfastness in full tone and is more suitable for demanding coating and plastic systems.

Is Pigment Orange 16 suitable for exterior paints?

No. PO16 is not lightfast or durable enough for exterior paint applications. It is best suited for interior inks, rubber products, and textile printing where long-term UV exposure is not a requirement.

Can Pigment Orange 16 be used in plastics?

Yes, in selected applications. PO16 is suitable for PE, PP, PS, and PVC coloring. However, because PO16 can migrate in PVC and other polymer systems, migration testing is recommended before commercial use.

What is the heat resistance of Pigment Orange 16?

Starwin Orange 16 has a heat resistance of 180–200°C, depending on dwell time and the specific application system. This makes it suitable for many ink, rubber, and plastic processing conditions.
