Fluorescent Pigment Sf-15 Fluorescent orange

The product is a fluorescent orange pigment identified as Sf-15. It has a specific gravity of 1.3 g/cm³ and a particle size of 3 µm. Heat resistance is rated at 230 °C, and its light fastness score is 4 on the standard scale. Oil absorption is reported between 30 and 35 g per 100 g of pigment.

Fluorescent pigments of this class are typically organic azo or quinacridone compounds that emit bright orange under UV light. In the industry, particle sizes commonly range from 5 to 15 µm, giving a density between 1.2 and 1.4 g/cm³, so the 3 µm size of this grade offers especially fine dispersion. Typical heat‑resistance limits for such pigments are up to 250 °C, placing the listed 230 °C within normal performance bounds. Light fastness values of 3‑5 are considered moderate, matching the supplied rating of 4.

The pigment is used in anti‑counterfeiting inks, security printing, decorative coatings, colour masterbatches and various plastic formulations. Buyers such as ink manufacturers, packaging converters and polymer processors often request sample quantities before committing to bulk. The listing does not state minimum order quantities, pricing or lead times, so these details should be confirmed directly with the supplier.

Tianjin Security Technology Development Ltd. Co. is based in Tianjin’s Nankai District, China, at Room 403 Building 3, No 4, postal code 300394. The company is listed as an imported‑tier supplier and carries a harbor trust tier, indicating it operates through recognised trade channels. Its product catalogue includes the Sf‑15 fluorescent orange pigment for a range of industrial applications. The public description highlights the pigment’s physical properties but does not provide additional corporate background.

Verification signals show a response rate of zero and no recorded average response time, suggesting the supplier has not replied to recent inquiries on the platform. Prospective buyers should therefore reach out directly to confirm the current availability and communication responsiveness. The supplier’s tier and trust designations imply compliance with basic import regulations, but no specific certifications are mentioned.
