Topwell, a trusted global supplier of specialty chemical additives, is pleased to announce the successful production and export of a 150kg commercial batch of our Water-Soluble 365nm UV Fluorescent Pigment (Blue Emission). The formulated powder is securely packed and currently en route to a European partner specializing in eco-friendly security printing and tracing solutions.
This successful delivery highlights Topwell’s commitment to supporting the European market’s transition toward low-VOC and water-based chemical formulations.
Formulated for Water-Based Systems
As environmental regulations tighten globally, conventional solvent-based security inks are rapidly being replaced by aqueous alternatives. However, many standard fluorescent pigments suffer from poor dispersion or clumping when mixed in an aqueous matrix.
Topwell’s specialized water-soluble grade resolves this pain point completely:
- Seamless Solubility: It dissolves rapidly and evenly in water without the need for aggressive milling or harsh chemical dispersants.
- Absolute Transparency: Once dissolved in water-based varnishes or inkjet fluids, the solution remains crystal clear and entirely invisible under standard daylight.
- Brilliant Blue Emission: Upon exposure to a standard 365nm UVA light, the printed or coated surface immediately emits an intense, high-contrast bright blue glow.
Secure Export Packaging
Given the highly hygroscopic (moisture-absorbing) nature of water-soluble powders, rigorous packaging is strictly required. This 150kg batch was meticulously sealed in double-layered, high-barrier moisture-proof bags, and housed within robust industrial fiber drums. This protocol guarantees zero moisture ingress during international sea freight, ensuring the pigment arrives at the customer’s facility in a dry, free-flowing state.
