| Test Name | Viscosity Reduction Testing for Unsaturated Polyester (UPE) Systems | Temperature/humidity | |||||
| Customer | You xing | Conducted by | Mr. Feng | Test Date | Sep.1 2025 | ||
| Objective | |||||||
| Color paste formulation | |||||||
| 1# | 2# | ||||||
| Unsaturated polyester resin | 50 | 40 | Sample | ||||
| Ground Calcium Carbonate | 50 | 60 | 400 mesh | ||||
| Dispersant | 0.2 | 0.2 | |||||
| Procedure | |||||||
| Mix at 500 rpm for 5 minutes under low temperature conditions (<30°C), as the resin contains 30% styrene. | |||||||
| Result | |||||||
| Viscosity Comparison | |||||||
| Viscosity mpa.s | Blank | Sample | 6503 | 6910 | 6910A | 6911 | 6500 |
| 1# | 16824 | 13168 | 7193 | 7304 | 8189 | 7746 | 11066 |
