Experimental record sheet
Test name: Solvent-free saturated polyester color paste with high pigment loading Temperature / Humidity: 12/68
Customer Long xing Applicant Lihui Feng Test date Jan.23 2026    

Test Objective:
To screen suitable dispersants using the customer-specified pigment loading. Both pigment and resin are customer-provided samples.

Procedure

After adding the materials step by step, disperse at 1500 rpm for 15 minutes. Then incorporate the color paste into the unsaturated base resin and store at room temperature for 7 days. The color paste should remain visually flowable, with no thixotropy observed.
