Notable Features

● Catalyst function friendly to human beings and the global environment

● Functional even in the darkness or under low temperature conditions, and

long-lasting odor eliminating, antibacterial and fungicidal effects

● Extremely useful in reducing harmful oxygen (antioxidant/radical scavenger

property)

● Odor eliminating effect on many substances such as:

・poisonous VOC/VVOC gas (formaldehyde and xylene andacetaldehyde.)

・major source of bad odor (ammonia and trimethylamine)

・main cause of body odor (isovaleric acid)

● Antibacterial action against staphylococcus aureus, bacillus coli, O-157,

MRSA, etc.

● Fungicidal property generating no resistant bacteria

This is a safe catalyst we have developed jointly with catalyst development and research groups both

inside and outside our country, using nano-tec. The redox reaction catalyst based on the electronic donor

and acceptor has been equipped with a variety of desirable functions.

What is the Diamond Magic of the UDD Catalyst ?

Feature of the UDD (Ultra-Dispersed Diamonds) ● Property UDD, ultra-dispersed diamonds are chemically stable as material.

Single UDD is shaped into sphere like and size of it is about 4～6nm

in particle diameter and 250～350 ㎡/g in specific surface area.

There is really hard core of diamonds with SP3 structure in the

middle of sphere.The shell of sphere is formed with non-crystal

carbon with SP2 structure and various functional groups such as

carboxyl, ester and amino group.

● Manufacturｉｎｇ Ｐｒｏｃｅｓｓ By bursting an explosive in the

ambie’nt without any oxygen,

mixture of diamond and non diamond

is produced and, through the

purification process, they become

uniform and well dispersed UDD in

aqueous solution.
