PlanoTek® HoCN - The high-performance coating for maximum surface protection

PlanoTek® HoCN is the innovative coating solution for the highest demands on surface protection. With over 75 years of experience as a coating expert, the De Martin Group is setting new standards in the functionality and durability of surfaces.

The unique PlanoTek® HoCN coating offers reliable protection for high-gloss polishes and at the same time serves as the perfect basis for high-gloss polishes. The coating significantly increases the durability of the polish and protects the surface from abrasion.

PlanoTek® HoCN is characterised by a 5-fold increase in hardness, resulting in outstanding wear protection. Even when processing aggressive media, the coating offers reliable protection against acidic and alkaline cleaners.

Another advantage is the avoidance of fretting corrosion and the undesirable eggshell effect. PlanoTek® HoCN gives you a uniform, hard surface for the best results

As a dimension correction to final dimension, PlanoTek® HoCN allows you to maintain the tightest tolerances. The coating can be used in a wide temperature range and therefore also offers excellent protection against hot gas corrosion.

Benefit from the versatility of PlanoTek® HoCN as a coating solution for tool and mould making, plastics processing and mechanical engineering. Increase the performance and efficiency of your applications with innovative coating technology from De Martin.
