Autonomic materials

Autonomic Materials offers a platform of self-healing additives enabling extended coating lifetimes and reduced asset maintenance costs. When added into a coating formulation, the self-healing additives provide improved corrosion resistance and coating adhesion at the site of damage. 

Self-healing mechanism in smart coatings: how does it work?

High performance coatings with self-healing additives become smart coatings and the protective nature of the coating is re-established after damage to provide continuous substrate protection.

What is the mechanism behind self-healing coatings?

The self-healing process is truly autonomous and does not require external energy. The trigger is the damage!

The process follows three main steps as described below:

The microcapsules are ruptured by the damage itself Microencapsulated delivery of liquid healing agent to the site of damage Healing agent polymerizes and heals damage

Autonomic Materials is the recognized leader in self-healing additive technology for high-performance coatings. Autonomic Materials offer solutions to prevent the costly problem of coating deterioration initiated and accelerated through common physical, mechanical, thermal and related everyday environmental stresses in the workplace. For a broad range of coating applications, from consumer to heavy industrial, our products impart unparalleled corrosion resistance, adhesion enhancement and extended service life after damage. 

The healing is effective on all levels of coating degradation from small scale to large scale damage:
Small-Scale Damage Large-Scale Damage
  • Multiple internal microcracks
  • Damage size < 50 um
  • Impact shocks, weathering, etc.
  • Damage size >= 500 um
  • Edges sealed off

Incorporation of Self-Healing Functionality into Coatings for Improved Corrosion Resistance after Damage

When exposed to the environment, metal substrates deteriorate due to corrosion. High-performance coatings are used to prevent the onset of corrosion.

Coatings, however, are often damaged by everyday stresses during a product’s life-cycle. The damage can take the form of small scratches or can be more extensive; it can be an isolated occurrence or caused by repeated wear of the same area. Even the most minor types of damage to a coating can lead to rapid deterioration in harsh environments, causing coating adhesion loss which typically leads to coating, and eventually, product failure.

The coating damage cannot always be immediately repaired as it may require taking the equipment out of service which can have significant direct and indirect costs. The challenge, therefore, is to design coatings which can self-heal after suffering physical damage and thus autonomically prevent coating adhesion loss around the damaged area.


New Construction Application: Extend Protection and Prevent Corrosion with Self-Healing

Corrosion is a primary cause of failure for steel constructions. A common way to protect the assets against corrosion consists of metallic powder pigments, usually zinc-based, with an electrochemical potential that is higher than that of steel.

Such particles create an electrically conductive net, which acts as cathode protection: they oxidize at the place of the protected substrate and when their resource is exhausted, the substrate can be cleaned and re-painted again. However, cracks form due to the atmospheric deterioration and oxidative zinc depletion. So, how can we prolong the service life of protective coatings?


Life-time Cost Analysis: Self-Healing Coatings Deliver Significant Savings for End-Users

Corrosion damage results in significant costs for asset owners. In the United States alone, the annual direct cost of corrosion is estimated to be $276 billion. Autonomic Materials self-healing additives reduces or even eliminates the need for maintenance of corrosion coatings, thereby decreasing the overall cost for corrosion protection.

Autonomic Materials additives convert standard protective coatings into smart-systems with the ability to automatically heal the coating when damage occurs. Download the case study to learn how self-healing coatings deliver significant savings for end-users.


How to get improved corrosion resistance in epoxy powder and fusion-bonded epoxy coatings with self-healing additives

High-performance coatings are required to protect metal from corrosion in demanding industries like oil and gas, heavy equipment and mining. While coating performance has been improved to provide longer and better protection, one critical issue remains: the exposure of metal after coating damage. Once the metal is exposed, corrosion spreads and coating adhesion is reduced. The challenge is therefore to develop a self-healing coating with the ability to maintain adhesion to the substrate after damage.

AMPARMORTM 2000, a microcapsule based self-healing additive developed by Autonomic Materials, is suitable for use in powder coatings to provide improved long term corrosion resistance.
