Metallic Luster Forming Film
PICASUS (Metal-Free)
An entirely new film with metallic luster without using metal
Objectives behind its Development
●Items: Environment-friendliness, light transmittance, electromagnetic wave transmission, formability
●Focus: To develop a film with superior properties of environment-friendliness, light transmittance, electromagnetic wave transmission and
formability by not using metal
●Impacts: We were able to achieve metallic luster and light transmittance with innovation of film structure alone.
The film can replace plating, coating and metal vapor deposition.
Features
Feature of the metallic luster forming film: metal free
1. Environmental aspect → free from metal plating and coating, recyclable
2. Electromagnetic wave transmission → does not block electromagnetic waves
3. Formability → free of cracks and blanching
4. Simple process → simultaneous forming and decorative carving enabled by insert molding
5. Diversified design possibilities → various designs can be added at the film phase
6. Corrosiveness → no possibility of corrosion because since no metal is involved
