Coatings - Fillers laboratories may also do the following tests:

Particle Size Analysis: Determines the size distribution of filler particles impacting the coating's final appearance and properties Testing
Specific Gravity Test: Measures the density of fillers which affects the weight and coverage of the coating Testing
Oil Absorption Test: Assesses how much oil a filler can absorb which influences the viscosity and drying time of the coating Testing
Moisture Content Analysis: Ensures fillers have low moisture to prevent adverse effects on coating durability and application Testing
Chemical Resistance Test: Evaluates the filler's stability and performance in various chemical environments Testing
Thermal Stability Test: Determines the filler's ability to withstand high temperatures without degrading Testing
Hardness Test: Measures the hardness of fillers contributing to the scratch and wear resistance of the coating Testing
