Indoor Low-Temperature Curing Physical Matting Agent VEL-308

Low-Temperature Curing Matting Agent VEL-308 for indoor powder coatings with conventional indoor 50/50 polyester resins can achieve 160°C/20min or 170°C/15min curing, and can also achieve 200°C/10min curing. It is a new cost-effective low-temperature curing matting agent.

Product Features

Appearance: White or light yellow powder.

Softening Point: 100-125°C.

Matting Performance: Adding 4% under curing condition of 160°C/20min or 170°C/15min can obtain 5-10% G60° gloss. Adding 3% under curing condition of 200°C/10min can obtain 3% G60° gloss.

Matting Principle: Non-wax, physical reaction, no extra consumption of epoxy.

Curing Condition: 160°C/20min or 170°C/15min, best in 170°C/15min for wider polyester choices.

Coating Surface: Flat and smooth, no yellowing, non-fuming when curing, impact resistance ±50kg·cm, excellent mechanical property.

Storage Condition: 28°C/12 months.

Cautions

1. Tested polyester resins with low film gloss under160°C/20min curing condition: Guanghua GH-1156, Xiangrong XR-5022X, Sino-French P5072, Shenjian SJ-3B.

2. Tested polyester resins with low film gloss under170°C/15min curingcondition: Sino-French P5072, Xiangrong XR-5022X, Zhengjie ZJ-5054, Shenjian SJ-3B, Yinyang YE-5050, Tiansong TS-5700, Guanghua GH-1156, Yochon YC-5012B.

3. It is recommended to conduct a small sample test before mass production.

4. The storage stability of powder coatings formulated with VEL-308 is good, but still need to avoid high temperature environment.

5. The above formulations are for reference only. Since the properties are different due to different resin manufacturers, please refer to the test data.
