Core Advantages (Performance based on factory TDS test conditions. Actual results may vary with formulation and do not represent end-use performance.)
1. Low molecular weight structure results in relatively low solution viscosity, suitable for high-solids formulation processing.
2. Soluble in esters, ketones, and aromatic solvents with clear solutions, showing solvent release characteristics in relevant systems.
3. Provides pigment wetting and dispersing assistance, supporting color development in ink systems.
4. Compatible with various film-forming resins, suitable for fast-drying ink and adhesive formulations.
5. Good powder flow properties for convenient feeding operations.
