Thanks to more precise ultrafine hollow bodies and the optimal combination design, Esscoat NF has a refractory structure certification with the minimum thickness in Korea.
Esscoat NF is an asbestos-free product made of perlite, which is free from the hazards associated with asbestos-containing materials.
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.
Esscoat NF has obtained environmental mark certification (environmental mark) and eco-friendly construction material certification (HB0 mark) with the highest rating.
Thanks to its ball bearing effect, which originates from the globular superfine hollow bodies, it not only offers outstanding constructability and dimensional stability, but also requires no surface coating for dust prevention, and is not prone to peeling-off, cracks, rust, etc.
