ExisitingTechnology

Until the development of S-DLC, exisiting DLC was aextremely advanced material for coating conductors andflexible materials, such as steel, stainless-steel and othermetal materials.
But coating an insulator and flexible material was thier
weak point.
S-DLC is the solution for these materials.

Able to Coat on Insulator

One of the problems of exisiting DLC was coating on insulator.
This was because of the electrostatic charge on the surface of thebase material.
S-DLC has solved this problem by thier unique coating process.
Atten: This unique process is the patent of iMott inc.

Able to Coat on Flexible Material
Please recognize that, as a molecule, S-DLC is not far different
from existing DLC. They both structured by carbon & hidrogen.
But as a meterial, S-DLC is far advanced because of its formation.
DLC is a very hard material which is an amorphous band of diamond and graphite. But as a film, it is also very thin. And becuase of its special characterisitic, DLC has been incompatible toflexible materials.
S-DLC has solved the problem by coating the DLC film into asegment form. This new segemented DLC is compatible to many
fkexible materials such as Rubber, Poly-carbonate and many otherplastics.

S-DLC can stand 2 〜 10 times more of deformation than exisiting DLC
S-DLC extremely extends the duration and life time of rubber, softmetal and plastics.
S-DLC extremely extends duration of life of rubber, softmetal and plastic surface.

Advanced Technology of Segmented DLC Generated by DC Pulse Plasma CVD

S-DLC (eternal carbon) has solved the fundamental problem of the exisiting DLC by simply sturcturing the DLCfilm into a micro tile form.
This enables the DLC film to go along with the materialexpansion.
Every material has its own coefficient of expansion. DLC
is a combination of Graphite & Diamond which has very
low expansion rate. And because of this reason, Exisiting
DLC was incotible with many materials.

S-DLC is Superior in 3 Usages from Exisiting DLC
1. Extrermely Tough in Abrasion

There are excess temperature and vibration on the surface of friction.
These factors are the cause of deformation of the material.
Exisiting DLC can easily peal off from these reasons.

2. Very low Friction Rate when Using Oil and other lubricants
The ditches of S-DLC enables to drain the abrasion powder and dust from the surface.
The surface friction rate will extermely decline using oils and other lubricants.

100 times
Existing DLC had a criticleproblem in Exfoliation.

The material of ec called DLC(Diamond like Carbon) is
a very hard material. Like diamond, simply hardness
does not mean that it is shock-resistant. An impact is
one of the enemy to a certain material. DLC had thesame problem for a long time. The Coating was too
hard to stick on to the deformation of the basematerial.
S-DLC had solved this problem by its unique structue.
Coating on a tough material surface, S-DCL was able
to stand 16 times more than the existing DLC.
