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. 

Differentiate your coatings by providing extended lifetime to reduce end-user maintenance cost

Autonomic Materials self-healing additives provide key benefits to high-performance smart coatings:

Corrosion protection
Extended coating lifetime and reduced maintenance cost
Improved protection with maintained adhesion
Potential for aesthetic recovery

Improved corrosion protection with self-healing coatings

Inspired by nature, Autonomic Materials self-healing technology repairs coating damage immediately after it occurs. The microencapsulated additives are compatible with most solventborne, waterborne and powder coatings and impart improved protection to metals, wood, concrete, plastic, composite and other substrates to ensure an additional level of insurance for end-users and asset-owners.

In the example below, the comparison between high-performance epoxy coatings with and without self-healing additives shows that the self-healing coating (5wt% microcapsule add-rate) is able to repair impact damage, prevent corrosion and maintain coating adhesion after damage (note: adhesion evaluated after 1,000 hours of ASTM B117 exposure).

Improved protection with maintained adhesion

A comparison of adhesion loss for a commercialized self-healing powder coating (epoxy primer containing microcapsules with a standard polyester topcoat) relative to a leading standard epoxy primer is shown below, demonstrating a significant life time extension enabled by the incorporation of self-healing additives.

The level of self-healing performance can be tailored to satisfy specific requirements of targeted end-use applications by adjusting the microcapsule add-rate (typically between 1 and 10wt%). Microcapsules are not recommended for addition to fully formulated coatings. Some degree of coating reformulation is typically required, such as proper selection of dispersing aids and adjustments of pigment volume concentration and pigment size distribution. 

Below is an overview of adhesion loss performance as a function of microcapsule concentration in a self-healing epoxy primer with a polyester topcoat on B1000 substrates: 

Extended coating lifetime and reduced maintenance cost

Autonomic Materials self-healing platform technology enables extended coating lifetime and reduced asset maintenance costs when using high-performance coatings by reducing both frequency and scope of required repair. 

Extra benefit! Less environmental impact due to longer maintenance cycles and fewer repaint events over the lifetime of the asset:

  • Reduced VOC emissions
  • Reduced energy use and carbon footprint
  • Reduced processing and application waste products

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.
