Anti-yellowing Agent L517
The polymer materials that composed the powder coatings will become yellowing because of high temperature oxidation or long-term air oxidation, and affect the weathering resistance of outdoor powder. L517 is a complex product screened out through several experiments. Each component works together and achieves the best optimum effect.
1. Technical parameters
Appearance: white powder
Melting point: 100-116 ° C
Volatile content: ≤ 1%
2. Application
Used for all kinds of thermosetting and thermoplastic powder coatings.
3. Use method
Dosage: 0.3-0.6%. Mixed with other materials and extruded.
4. Product characteristics
Prevent coating become yellowing when baking at high temperature. The effect is better for pure polyester powder.
Prevent oxidative yellowing when powder coating long term exposures to air, improving weathering resistance.
The effect will be better if used with ultraviolet absorbent. Indoor powder will also prolong the weathering resistance for 2-3 years.
5. Storage
Store in cool and dry place. Keep away from fire and heat sources.
6. Packaging
Kraft paper bag (polyethylene liner). Net weight: 25kg/bag
