HIFFICIENCY® relies on robust, PFAS-free non-stick coatings - developed from over 30 years of coating research. They aren't just a replacement for classic fluoropolymer coatings (PTFE, PFA, Teflon), but technically superior to them in many respects.
As early as 1998, Dr. Stecher developed his first pan coating without PTFE/Teflon - because he recognized the risks of this group of substances early on. This research led to an independent coating system: OBSIDIAN SHELL® - a high-performance non-stick coating on a purely mineral basis, refined over years for non-stick properties, durability and temperature resistance. Today this PFAS-free coating has won awards (Wilhelmshaven Innovation Award 2023) and covers several functions at once: non-stick, wear protection/gliding, corrosion protection, and electrical and chemical insulation.
OBSIDIAN SHELL® is our entirely new non-stick coating on a purely mineral basis - made from components such as corundum, feldspar, sapphire, silicon and titanium. Completely without PFAS, PTFE, PFOA or other plastics. The principle comes from nature: just as hot lava solidifies into obsidian, our mineral coating powder is liquefied under intense heat and cooled in a flash. The result is an extremely robust, deep-black surface with an outstanding non-stick effect - free of toxic chemicals.
The non-stick effect is created by a unique silicon structure that not only seals the surface but runs through the entire coating. This keeps the non-stick performance at the highest level over the full lifetime - not just at the beginning. OBSIDIAN SHELL® withstands temperature peaks of up to 450 °C without any loss of performance and without harmful off-gassing. Unlike plastics such as PEEK or classic ceramic coatings, performance stays stable for good.
Faster heat absorption, shorter frying and baking times, lower energy consumption, no baking paper, easy cleaning, longer durability. Bottom line: lower cost per cooking or baking cycle.
Fast heat absorption saves time and energy.
Reliable non-stick performance over the entire lifetime.
Less effort, no baking paper.
Up to 10,000 cooking or baking cycles.
