- Fast surface drying with good through-dry capability
- High gloss and good gloss retention
- Good hardness development with maintained flexibility
- Resistance to yellowing and good color stability
- Compatible with various solvents (aliphatic, aromatic, oxygenated)
- Excellent adhesion to metal and wood surfaces
Properties:
- Industrial coatings: primers, enamels, machinery paints, metal finishes
- Decorative paints: interior and exterior gloss paints, topcoats
- Wood finishes: varnishes, furniture coatings
