Test record sheet
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.
