Title:

Self-Healing Anticorrosive Coating For Steel

Value Proposition:

Periodic maintenance costs for corrosion protection of steel structures can be saved through the use of this self-healing coating.

Summary Application:

The autonomous self-healing coating is triggered in presence of water/moisture, coating can be used for long term maintenance-free corrosion protection of steel structures

  • The polymer-based composite self-healing coating
  • Autonomous self-healing is triggered in presence of water/moisture
  • Coating passes 1000 hours of salt spray test after breakage of coating
  • Adhesion strength: > 10 Mpa
  • Hardness: 190 HB, Modulus: 4 GPa
Advantages:
  • Can be applied by brushing or spraying
  • Coating cures in ambient conditions in 24 hours
  • Suitable for onsite application
  • Scalable and Economical
