Esscoat NF-III
Esscoat NF-III


Minimum Coating Thickness

Thanks to more precise ultrafine hollow bodies and the optimal combination design, Esscoat NF-III has obtained a refractory structure certification with the minimum thickness in Korea.

Asbestos and Vermiculite-free

Esscoat NF-III is an asbestos-free product made of perlite, which is free from the toxicity or hazardousness of asbestos-containing materials.

Outstanding constructability and quality stability

Thanks to the ‘ball bearing’ effect created by the globular superfine hollow bodies, it not only features outstanding constructability and dimensional stability, but also does not require surface coating for dust prevention, and is not prone to peeling-off, cracks, rust, etc.
