Company Technology
Established in May 1999, Nanofilm Technologies International Pte
Ltd is an internationally recognized authority in the field of
Filtered Cathodic Vacuum Arc (FCVA) Technology. Our FCVA
coating technology represents a significant advancement in thin
film deposition, and is the result of 7 years ground-breaking work
by a team of researchers led by Associate Professor Dr. Shi Xu,
the Chairman and co-founder of Nanofilm.
Our FCVA Technology has received numerous academic awards,
including the prestigious Singapore Innovation Award & National
Technology Award conferred by the National Science & Technology
Board of Singapore. Nanofilm has a portfolio of patents covering
various areas of FCVA Technology and its applications.
Company Technology
Arc-evaporation deposition is normally
used to apply wear-resistant coatings to
machine tools. However, the substantial
distribution of macroparticles associated with
this process limits the film quality. To solve
this problem, Nanofilm Technologies
International Pte Ltd has developed a
revolutionary new version of FCVA deposition
technology. Our patented technology can
produce high quality Tetrahedral Amorphous
Carbon (ta-C) coatings to satisfy even the
most stringent requirements.
During deposition, the surface
temperature of the substrate is generally
below 70 °C, which makes coating on plastic
possible too.

 TAC-ON coated mirror molds experience lesser wear
 Better adhesion strength on mold surface as compared to conventional DLC coating.
 Mold release and fillings are easier and smoother due to the low surface energy of TAC-ON
coated mirror mold.
Advantages of ta-C coating on mold :
Film thickness is low yet harder
Surface Energy is small and contact angle is high
Excellent adhesion
Excellent Anti-Sticking properties
Low wear rate
Lower-coefficient of friction
Achieve better easy release property
