ASTRA LA®
Silicone Leveling Agents
Silicone leveling agents to improve flow and leveling of coatings. Eliminate brush marks, orange peel, craters. High compatibility with various binders, weather resistance.
Why silicone leveling agents?
Brush marks, orange peel and crater defects are the hallmark of poor leveling. Silicone leveling agents migrate to the surface during film formation and create a smooth, even, defect-free finish. They also improve slip and weather resistance.
Key Benefits
- Eliminates brush marks and orange peel
- Crater prevention
- Surface slip and scratch resistance
- Weather and UV resistance
- High compatibility across binder systems
- Anti-graffiti grades available
Impact on Coating Performance
Silicone leveling agents from ASTRA LA bring premium-grade finish to coatings — the kind that customers can see and feel. Essential for automotive, furniture and high-end industrial applications.
O – organosoluble, WB – water-based, RC – radiation-curable
