ASTRA LA NS®
Non-Silicone Leveling Agents
Non-silicone leveling agents for processes where silicone is undesirable. Improve flow and leveling, providing smooth even surfaces.
Why use silicone-free leveling agents?
In automotive refinish, food packaging and electronics, silicone contamination is unacceptable. Non-silicone leveling agents from ASTRA provide smooth, even finishes without compromising recoatability or adhesion.
Key Benefits
- Silicone-free — safe for recoat and overspray zones
- No inter-coat adhesion issues
- Smooth, even finish
- Compatible with waterborne and solvent systems
- Crater prevention on difficult substrates
- Ideal for automotive refinish
Impact on Coating Performance
ASTRA LA NS leveling agents deliver professional-grade finishes in sensitive applications where silicone is prohibited. Critical for automotive refinish, can coatings and food contact materials.
O – organosoluble, WB – water-based, RC – radiation-curable
