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.

Why it’s time to embrace digital colour masters

A combination of digital standards and industry-leading instruments enables businesses to reduce costs and wastage across the entire supply chain by getting the colour of every component right first time.

Investment in R&D excellence from quality control instrument specialist BYK-Gardner enables companies across the globe to achieve consistent measurement and control of important characteristics such as colour. And not just colour. BYK-Gardner instruments measure many other characteristics such as gloss, orange peel, multi-angled colour, sparkle, graininess, colour fastness, cloudiness, transparency, clarity and haziness.

This is achieved through industry-leading LED illuminated instruments with optimal inter-instrument agreement and enables true full digital masters to be introduced for all these characteristics. The digital masters can easily be distributed through the supply chain making a digital approval process possible at every stage, in every location from beginning to end.

Guarantee repeatable product quality across time and space
Digital masters include spectral data and client requirements, while also allowing automatic colour identification where appropriate. Measurement tolerances and an instant pass/fail can be included on both hand-held and robotic installations. The result is self-approval throughout the supply chain and improved harmony between products to guarantee a high right-first-time rate.

Working with major manufacturers across many industries, the benefits from reductions in waste and delay as well as improvements in communication of measurement data, to productivity, quality and sustainability deliver a complete return on investment – the instruments can pay for themselves!
Digital masters can be sent by e-mail as an xml file to locations anywhere in the world. They have applications within industries including automotive, coatings, plastics, printing inks leather and even wine.

Blagden distributes BYK-Gardner instruments to companies across the United Kingdom. To find out how your business can benefit from the use of these instruments in combination with digital masters, call Simon Moss at Blagden on 01959 560818 or email.
