Self-Healing

NANOMYTE® MEND Self-Healing Coatings

Healing_MEND2NEI has developed a line of self-healing top coats, where a physical self-healing phenomenon leads to gap closing and crack sealing. The innovative technology platform is applicable to a broad range of substrates, such as metal, wood, and polymers – including those that require maintaining a clear glossy appearance.

NANOMYTE® MEND coatings can be healed multiple times at the same defect location, thereby reducing life cycle costs by increasing the service life and reducing maintenance costs of the various substrates to which it is applied. In response to the need for self-healing required in different environments, four MEND products have been introduced:

The MEND coating platform is based on polyurethane, but the principle can be applied to other coating systems as well. NANOMYTE® MEND coatings can be healed multiple times at the same defect location. The properties of the coating, such as hardness, gloss, and refractive index, can be altered as needed for a specific application.

Four Formulations

The NANOMYTE® MEND line of self-healing coatings is available in four different formulations, with varying temperatures for curing & self-healing.

MEND_Selection_Guide

NANOMYTE® MEND 1000

MEND 1000 is a thermally-induced, self-healing coating. The 2-part coating involves a unique phase-separated morphology that facilitates the delivery of the self-healing agent to the damage site (such as a scratch or crack) thereby restoring the coating appearance & function. The coating can be self-healed by the application of warm air for several seconds with a simple device, such as a household hair dryer.

MEND 1000 Properties

  • Base Solvent: Toluene
  • Curing Temperature: 60°C (min.)
  • Healing Temperature: 60 – 80 °C

NANOMYTE® MEND 2000

MEND 2000 is a room temperature, self-healing coating. The 2-part coating involves a unique phase-separated morphology that facilitates the delivery of the self-healing agent to the damage site (such as a scratch or crack) thereby restoring the coating appearance & function.

MEND 2000 Properties

  • Base Solvent: Toluene
  • Curing Temperature: 35°C (min.)
  • Healing Temperature: 25°C (min.)

NANOMYTE® MEND 3000

MEND 3000 is a 2-part, solventborne, self-healing coating that can be cured at room temperature.

MEND 3000 Properties

  • Base Solvent: Toluene
  • Curing Temperature: 20°C (min.)
  • Healing Temperature: 60 – 80 °C

NANOMYTE® MEND 4000

MEND 4000 is a crystal clear, fast drying, high gloss protective finish for use over bare or stained wood, paint, plastics and metal. The waterborne formulation is low-odor and may be cleaned up with soap and water. The dry film has unique self-healing properties upon application of mild heat (60°C / 140°F) for several seconds, enabling a complete and rapid removal of many types of scratches and swirl marks which may accumulate with use.

MEND 4000 Properties

  • Base Solvent: Water, Glycol Ether
  • Curing Temperature: 25°C (min.)
  • Healing Temperature: 60 – 80 °C

Available for Purchase
