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

Stop Costly Resprays: 3 Lab Checks to Fix Gloss Loss in Paint
Gloss loss, often called dieback, is the dulling or hazing of a paint film after it appeared to cure normally, and it almost always traces back to solvents still trapped beneath the surface or a curing reaction gone wrong. The immediate action is simple: stop applying additional coats, give the film uninterrupted cure time in stable conditions, and check tack before deciding whether the problem is application error or something deeper in the formulation.
