| Test Name | Pearlescent Pigment Test for Aerosol Spray Paint | Temperature / Humidity | 14/87 | ||||
| Client | Applicant | Mr. Feng | Test Date: | 26.4.8 | |||
|
Objective: The customer requires the pearlescent paint to be thinned to spray viscosity, and to resolve the issues of pearlescent pigment settling and orientation during spraying. Two resin samples from the customer were used, with xylene as the test solvent. |

| Before Storage | After 5 Days at Ambient Temperature | ||||||
| After 5 Days at 55°C (Hot Storage) | |||||||
|
Observation: No separation after 5 days at ambient temperature. Slight soft sedimentation after 5 days at 55°C (hot storage). These four options can be recommended to the customer. Pearlescent pigment orientation after spray application is acceptable. |
