Typical Applications
Clear Protective Coatings
Provides blue light protection for automotive clear coats, industrial topcoats, and electronic device coatings where high gloss and optical clarity are essential.
Transparent Plastic Components
Protects see-through plastic parts used in consumer electronics, medical devices, and automotive interiors from blue light-induced yellowing and degradation.
Optical Covers and Lenses
Ideal for eyeglass lenses, camera lens covers, display windows, and protective shields requiring both blue light filtering and exceptional visual clarity.
High-Gloss Industrial Finishes
Preserves the appearance of high-gloss finished surfaces on appliances, automotive trims, and luxury goods by preventing blue light-induced color shift and gloss reduction.
Light-Transmitting Plastic Parts
Suitable for light guides, diffusers, and transparent housings where blue light protection must be achieved without compromising light transmission efficiency.
Why Use UV‑380
UV-380 is ideal for products where both protection and appearance matter. It delivers effective blue light filtering without introducing yellowing or haze, making it the preferred choice for premium optical and clear coating applications. Unlike many blue light absorbers that impart noticeable color or reduce transparency, UV-380 is specifically engineered for high-clarity systems where visual quality is paramount. The 380nm absorption peak is strategically positioned to target harmful blue-violet light while minimizing interference with visible light transmission
Recommended Dosage & Processing Guidelines
For optimal blue light protection in transparent applications, a recommended dosage of 0.3-1.5% (by weight) is suggested depending on application requirements and desired protection level. For optical-grade applications, lower dosages may be preferred to maintain maximum light transmission. UV-380 is compatible with standard processing methods including extrusion, injection molding, casting, and coating application. For specific formulation guidance, contact our technical support team.
