MERIT & DEMERIT
1. good liquidity, excellent flatness
2. tough coating, good flexible
3. good adhersion, impact resistance
4. fine electrostatic spray, can thin coating
5. heat resistance, fine anti-yellowing
6. poor weatherability, pulverization for long-term ourdoor insolate
7. average coverage 9-12m/kg, coating thickness 60m
