● AMTECLEAN Z is antimicrobial agent composed of Silver and Zinc Oxide. We offer two grade of the product depending on the enviroment of usage.
● By composing to many kind of materials, like Resins.Paints,Filters,Elastomers,non-woven fabric, AMTECLEAN Z provides powerful compound effects.
● In addition to Antimicrobial effect, Antifungal Effect was achieved.It develop to wide range of field like Home electoronics, medical business and household goods.
● High performance of Antimicrobial and persistence of Silver and Zinc Oxide produce greatly effects with less amount.
● AMTECLEAN Z is antimicrobial agents is composed of two metal compound Ag and Zn.
Antimicrobial property of Silver and persistence of Zinc Oxide perform Synergistic effect.
● Compouding special zinc oxide single-crystal "AMTETRA " correspond to a variety of composit matrix.

AMTETRA consists of a zinc oxide single crystal in a tetra-pod shape with semiconductor characteristics, and is excited by ultraviolet irradiation to cause electro-chemical decomposition and release electrons, thereby generating electron holes in the valence band and tend to become electrically neutral. This property deprives electrons of nearby organic material by cutting the molecular bond and generates a photocatalyst effect of decomposition.
[Water purification experiment by activating photocatalyst effect]
Evaluation of oxidative decomposition of pigment component in water by photocatalyst effect.
The blue pigment Indigo Carmine is used as a color component.
Indigo Carmine has large light absorption properties near 610 nm caused by a chromophoric group, and the light absorption is reduced by decomposition and purification of the photocatalyst effect.
AMTETRA is a zinc oxide single crystal in a tetra-pod shape with semiconductor characteristics, and the direct transition by electrons'
excitation generates sharp absorption from 375 nm, which is equivalent to the band gap, demonstrating the attributes of a good UV absorption material.
It also shows high reflection rate over a wide light band from visible light to near infrared, thereby presenting as white color powder.
