Core Advantages
1. Powerful UV absorption & shielding slows down chalking and fading of outdoor coating and plastic articles significantly.
2. Great pellet flow supports high-loading masterbatch extrusion without extruder blockage & uniform mixing.
3. Low impurity prevents pinhole & particle defects on outdoor paint film.
4. Pure blue undertone resists yellowing after long-term outdoor exposure.
5. Full compatibility with solvent and waterborne resin systems.
Main Application Fields
Core Applications: Outdoor Industrial Metal Topcoat, Outdoor Plastic Pipe & Profile, Weather Resistant Masterbatch
Compatible Applications: Exterior Architectural Coating, Anti-Corrosion Pipe Coating, Agricultural Film Colorant
Forbidden Scenarios: Food-contact products, Electrostatic Toner, Ultra-High Gloss Mirror Ink
Handling Precautions
1. Combine antioxidant and light stabilizer in outdoor formula to extend weather resistance service life.
2. Pellets feed directly to extruder without pre-sand milling; powder version needs high-speed pre-dispersion.
3. Coating dosage:1.3% ~ 3.8%; masterbatch dosage:2.0% ~ 4.8%.
4. Store away from moisture; damp pellets crack easily to generate dust.
