Corrosion Resistant Nano-Paint
Corrosion resistant paint for Coating for Steel Structures subjected to Industrial and Marine Environment
Important Properties
- Paint classification after 1000 hours of salt spray test (ASTM B 895): Class – A
- Higher impedance property implies better corrosion resistant property.
- High scratch resistance
- Improved hardness properties
Salient Features:
- Improved mechanical Properties such as Scratch Hardness, Pull of Adhesion & Impact Hardness
- Enhanced corrosion Resistance
Field Trials:
- Successful field trials completed at two costal locations for comparison with conventional paint
