Fluorescent Pigment SF-21H Magenta (Bluish)
The Fluorescent Pigment SF-21H Magenta (Bluish) is supplied by Tianjin Security Technology Development Ltd. Co. in China. It has a measured specific gravity of 1.3 g/cm³ and an average particle size of 3 µm. The pigment tolerates temperatures up to 230 °C before colour degradation. Light fastness is rated at level 4, and oil absorption lies between 30 and 35 g per 100 g of pigment.
This colourant belongs to the organic azo‑based fluorescent pigment family commonly used in security inks. Industry practice places typical particle size tolerance at ±0.5 µm for consistent print quality. Standard heat resistance for comparable pigments ranges from 200 °C to 250 °C, matching the supplied 230 °C value. Typical oil absorption for this class is 25‑40 g/100 g, aligning with the reported 30‑35 g range.
Primary applications include anti‑counterfeiting inks, security printing, decorative coatings and colour masterbatches for plastics. Buyers such as document‑security firms, packaging manufacturers and colour‑specialty processors frequently source this grade. Samples are available on request and trade terms should be clarified with the supplier, including FOB or CIF conditions and any minimum order requirements.

Sourcing Fluorescent Pigment SF-21H Magenta (Bluish) from Tianjin Security Technology Development Ltd. Co. - China Import Guide
Before placing an order, importers should request a Certificate of Analysis confirming the pigment’s specific gravity, particle size and oil absorption values, as well as a batch‑wise safety data sheet. Verifying the colour index and confirming that the pigment meets any relevant regulatory limits for the intended market will reduce the risk of non‑compliance. It is also prudent to ask for a sample to evaluate dispersion performance in the buyer’s own formulation.
Logistics discussions must clarify the preferred Incoterm, whether FOB Tianjin port or CIF to the destination port, and the expected lead time, which the supplier has not disclosed publicly. Buyers should negotiate payment terms, typically a letter of credit at sight or a 30‑day open account after shipment, and confirm any handling fees associated with bulk drum transport.
Quality assurance can be reinforced by arranging a third‑party inspection before loading, focusing on pigment colour consistency, moisture content and particle size distribution. Importers should also ensure that the supplier can provide the required documentation, such as a material safety data sheet and any export licences, to satisfy customs and end‑user specifications.
