Today, thin films are used in a broad variety of applications and industries, including anti-reflection coating of lenses, laser filters, mirrors, liquid crystal display panels and architectural glass. The sources of these thin films are evaporation materials, which are manufactured in many types, sizes and shapes to meet various needs. Since starting the mass production of evaporation materials in 1977, Canon Optron has continued to provide customers with quality evaporation materials that address their needs by taking advantage of our technologies for powder controlling/forming and sintering/melting.
The recent advancement of technologies has increased the demand for higher quality thin films. Accordingly, evaporation materials also are expected to be of higher quality and function. Under these circumstances, Canon Optron continue to provide the highest quality evaporation materials suited to various methods for thin film manufacturing by taking advantage of our sophisticated technologies developed through our R&D efforts.

Pellet-type Materials
Easy-to-use, pellet-type materials of various shapes are available, allowing for choosing the one best suited to your hearth liner. Also available are pellets of high thermal shock resistance material that can tolerate the high energy from an electron gun or other energy source.

Granule-type Materials
Granule types let you add evaporation materials as needed, so they are suited for continuous evaporation. We also provide low gas granules that emit only a low level of gas, preventing adverse effects on the strength and durability of the film.

Functional Materials
Functional materials are evaporation materials, which are used to fabricate organic thin films having special functions such as water repellency, antifouling property or other non-optical properties. Unlike the conventional coating method using a solvent, it is possible to proceed to the water repellent or antifouling processing stage just after the anti-reflection coating process because the coating is done by vacuum evaporation.
About OF-SR
Characteristics of OF-SR
- Water repellent: reduces water absorption and prevents dried water stains or rust
- Antifouling: prevents fingerprints, allows easy wiping and enhances durability
- Scratch resistant: makes less susceptible to scratches due to decreased friction
- Process: uses a standard vacuum evaporation process for film formation (resistance heating or electron gun method)
Effects are more manifest on a glass substrate or SiO2 film.
Basic Features
- Contact angle (2.5 L): 110 (pure water), 70 (Squalan oil)
- Sliding angle (5 L): 6 (pure water), 2 (Squalan oil)
- Abrasion resistance: 1900 times or more (steel wool, 1 kg)
- Humidity resistance: no change in contact and sliding angles after 240 hours at 60C/90%
Abrasion Resistance Test

- Abrasive material: steel wool (#000)
- Friction load: 1 kg
- Friction distance (speed): 10 mm (40 mm/s)
- Times of repeated friction: 20
The ink wiping test was performed every 20 frictions until it failed.
