Contract coating processing: Unique surface treatment technology that can improve the release properties of 'molds' for optical components! Sample testing available.

The organic nano-thin film treatment technology "NANOS" allows for the application of functional films that enhance water repellency, oil repellency, anti-fouling (fingerprint resistance), and slip properties (dynamic friction coefficient) on metal and glass substrates such as stainless steel (SUS) and nickel (Ni) through spray treatment and vacuum deposition using a special fluoropolymer. The maximum temperature of the entire process is 80°C, resulting in minimal thermal impact on the substrate, and being colorless and transparent, it has little effect on optical properties. 【Examples of Adoption】 ■ Target: Molds for optical components ■ Purpose: Improved release properties 【Features】 ○ Excellent water and oil repellency Pure water: over 110°; n-hexadecane: over 68° ○ Control of thin film thickness Spray treatment: 5–10nm (can be controlled in 1nm increments) Vacuum deposition: 5–45nm (can be controlled in 5nm increments) ○ Minimal impact on optical properties (colorless and transparent) ○ Low-temperature process Our surface treatment methods include both deposition and spray methods. You can specify the treatment method or leave it to us. Please feel free to consult with us! (Sales of the main machine are subject to consultation)

basic information

**[Adoption Results and Effects]** **[Spray Method]** ○ Contact glass for scanners → Prevents dirt adhesion, improves maintenance ○ Optical components (lenses, cover glass, etc.) → Provides water repellency, prevents dirt (fingerprint) adhesion ○ Touch panels → Prevents dirt (fingerprint) adhesion ○ Metal masks for solder printing → Improves printability, reduces maintenance **[Vacuum Deposition Method]** ○ Inkjet heads → Improves printability ○ Molds for optical components → Improves release properties ○ Stamping molds → Improves release properties, shortens tact time ○ Molds for nanoimprinting → Improves release properties, high conformity to fine shapes ○ Jigs for transfer processes (such as gravure) → Improves transferability (release agent-free) ○ Photomasks → Prevents adhesion of resist ○ Probes for AFM and STM → Prevents adhesion of foreign substances ● For more details, please contact us or download the catalog.
