Self-healing additives can be used to improve the performance of a coating system that is subject to mechanical damage, micro-cracking and subsequent corrosion of the substrate while in service.
This article reports on our evaluation of AMPARMOR™ 2000, an additive designed to impart self-healing functionality to fusion-bonded epoxy (FBE) and epoxy powder primer coatings, and AMPARMOR 3000, designed as an option for nonepoxy coatings.
Self-healing polymers are a class of smart materials that have the capability of autonomically repairing themselves after damage, without the need for detection or repair by manual intervention.
