Flexible Ceramics may seem like an oxymoron: everyone knows ceramics are brittle. But EonCoat is a ceramic that has all of the benefits of a ceramic coating and yet can flex with a metal substrate, up to and beyond the point where steel permanently deforms.
EonCoat ceramics have more flexibility (or ductility) than is needed to handle the typical movements of steel - including flexing, expansion, and contraction – found in:
Ordinary fired ceramics are brittle; they have less than 1% ductility. Various steels will demonstrate 7% to 38% ductility before failure and 1% before permanent deformation. Because steel can flex and ceramics can’t (until now), using a true ceramic coating on steel would not be practical. Previously, so called ceramic coatings for steel have just been polymer coatings filled with ceramic beads.
Independent tests done by Dwight Weldon of Weldon Labs (author of the book “Failure Analysis of Paints and Coatings”), show that EonCoat sretches 19% prior to failure, more than enough to handle the ordinary movements of steel.
EonCoat ceramics have fibers and fillers with an acicular structure to create toughness and additional ductility (flexibility). This isn’t possible with traditional ceramics because fibers cannot withstand their firing. But the EonCoat exothermic reaction creates a heat rise of only 7° to 40°F (4° to 22°C), so a wide range of materials can be used for performance enhancement.
EonCoat coatings also have very good impact resistance:
EonCoat coatings can take a significant blow without showing damage.
