Functional Materials

Ultrafine Particle Size Zinc Oxide, FZO

ISK has developed ultrafine zinc oxide, FZO-50, in addition to ultrafine titanium dioxide.
FZO-50 is superior in UV-A shielding, whereas ultrafine titanium dioxide is superior in UV-B shielding.
FZO-50 shows anti-bacterial and deodorizing effects as conventional zinc oxide does.
FZO-50 can be utilized in various applications such as cosmetics, films and coatings.

Strengths

1. Strength 1
   ISK’s proprietary atomization technology achieves transparent and excellent ultraviolet (UV-A) shielding.
2. Strength 2
   ISK delivers products of stable quality using manufacturing technology that the company has developed over many years.

Typical Applications

• Cosmetics
• Industrial films
• Paint
