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 additives platform for corrosion protection

Autonomic Materials offers a platform of self-healing additives used in high performance coatings to repair coating damage immediately after it occurs. Self-healing additives extend long term coating performance by imparting extreme corrosion resistance, maintained adhesion and extended service life after damage in a wide range of applications from high-performance systems for oil & gas and industrial maintenance to consumer applications.

What is a self-healing additive?

A self-healing additive is used in coating formulations to provide autonomous corrosion protection and prevent undercut adhesion loss when damage occurs. This self-healing property makes the coating a functional and smart coating: functional because it acts as a corrosion protective coating and smart because the healing is automatically triggered by the damage itself. Self-healing additives provide a dynamic functionality to protective coatings by regenerating critical protective properties in the damaged area of the coating. In traditional protective coatings, the protection is typically provided by a static (or non-responsive) property of the coating (hydrophobic coatings for example).

Autonomic Materials, the leader in self-healing additive technology

Autonomic Materials is the recognized leader in self-healing additive technology with a broad portfolio of innovative products based on microencapsulated liquid healing agents which enable standard coatings to become self-healing coatings. Autonomic Materials offers a selection of microcapsules designed to meet the specific requirements of your targeted coating system.

What are the benefits expected from self-healing additives in high performance coatings?

Deterioration of a coating due to physical, mechanical, thermal or related everyday environmental stresses in the workplace leads to moisture penetration and corrosion of underlying metal substrates as well as structural and/or biological degradation of wood, concrete, etc. With self-healing additives incorporated in the protective coating, the degradation process activates the autonomous delivery of microencapsulated liquid agents to enable:

  • Extended coating lifetime
  • Improved asset protection
  • Reduced maintenance cost

Below is an example of the performance you can expect by using the self-healing additives: full protection over time and no exposed metal!

Case Studies from Self-Healing Technologies for Coatings

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.
