ASTRA F®
Functional Additives
Catalysts, dryers, antistatics and special additives to improve performance: elasticity, moisture resistance, salt spray resistance, hardness, conductivity.
Why functional additives matter
Functional additives are catalysts, dryers, antistatics and special compounds that fine-tune the performance of coatings. They improve elasticity, moisture resistance, salt-spray resistance, hardness and even electrical conductivity — properties that base resins alone cannot deliver.
Key Benefits
- Crosslinking catalysts for faster cure
- Drying accelerators for alkyd systems
- Antistatic properties for sensitive surfaces
- Improved elasticity and moisture resistance
- Enhanced hardness without brittleness
- Salt-spray and corrosion protection boost
Impact on Coating Performance
ASTRA F additives let formulators differentiate their products with measurable performance gains: higher hardness, longer salt-spray hours, better elasticity. Critical for industrial, marine and consumer-grade coatings.
O – organosoluble, WB – water-based, RC – radiation-curable
