Self-healing additives for improved corrosion resistance and coating adhesion after damage


Autonomic Materials is the recognized leader in self-healing additive technology for high-performance coatings, adhesives and sealants.  For a broad range of coating applications, from consumer to heavy industrial, Autonomic’s products impart unparalleled corrosion resistance, adhesion enhancement and extended service life after damage.

SELF-HEALING COATINGS FOR IMPROVED SUBSTRATE PROTECTION

Autonomic’s self-healing technology repairs coating damage immediately after it occurs. Autonomic’s microencapsulated additives are compatible with most solventborne, waterborne and powder coatings and provide improved protection to metals, wood, concrete, plastic, composite and other substrates. Three series of products are available in both wet and dry form:

  • Amparmor 1000 – Dual capsule system based on reactive silicone polymers with ability to cure under water
  • Amparmor 2000 – Single capsule system based on solvent-promoted cure of epoxy resins
  • Amparmor 3000 – Single capsule system based on oxygen-initiated cross-linking of functionalized alkyd resins

HOW THE SYSTEM WORKS

GENERAL APPLICATION GUIDELINES

AMPARMOR microcapsules are not recommended for addition to fully formulated coatings. Some degree of coating reformulation is typically required, including:

  • Adjustment of pigment volume concentration
  • Adjustment of pigment size distribution
  • Adjustment of resin chemistry to achieve desired Tg
  • Proper selection of dispersing aids

Autonomic’s self-healing microcapsules are stable under typical storage conditions. Caution must be exercised when incorporating capsules into coating formulations as excess shear and/or grinding may cause capsules to rupture.

 

  • For liquid coatings, the addition of microcapsules is recommended during the letdown stage.
  • For powder coatings, capsules should be added as a dry blend after extrudate grinding.
