Technology
How Akusta Works
Endothermic mineral technology creates a protective barrier and helps delay fire.
Heat in~270 °CCoolingStable
01.
Heat Exposure
Flame contact transfers heat into the material surface.
02.
Endothermic Reaction
At approximately 180-200 C the mateiral absorbs heat and releases cooling water vapour
03.
Heat penetration delayed
Water vapour cools the material heat transfer significantly delayed
04.
