| Résumé : |
The concept of self-healing was developed to increase to reliability and service life of coating systems in a wide variety of applications and then minimising the cost of maintenance and rehabilitation.
Relevant existing strategies to accomplish self healing have been investigated : micro-encapsulation of healing agents, resins with high flow behaviour and other emergent techniques.
In this paper, self-healing using microencapsulation wil be discussed. Commercially available paints for corrosion protection and for exterior wall usage were selected. Custom made microcapsules containing oils or corrosion inhibitors, of various diameters and various shell compositions were added to those paints in different concentrations. The self healing process has been followed by visual inspection and accelerated corrosion tests. Strong dependencies and limitations were pointed out : concentrations of capsules, nature of the core, diameter and type of paints. The challenge is to find to appropriate microcapsules to embed in the paint. |
