NOSTRA™ is an ultraviolet light- (UV-) hardened coating developed using proprietary Mitsui Chemicals technology that resists fogging up and getting dirty.
The material has been given excellent dirt resistance, anti-fogging properties, easy washability, abrasion resistance, anti-static properties, and fast-drying properties.
Instantaneous drying (in several seconds) is a major feature, and the product is also attracting attention due to its resource-saving properties (low volatilization and low energy use) and amenability to production at volume as demand for such products rises in a broad range of fields.
1. Easily washable; sheds dirt easily
NOSTRA™ makes it easy to remove dirt with water.

The material can be used to prevent accumulation of water scale

2. Resists fogging up
The material resists fogging up, making even glass surfaces in high-humidity environments resistant to condensation.

3. Dries quickly
Thanks to the material's super-hydrophilic properties and a water contact angle of 10° or less, water drains quickly away without forming into droplets so that the coating dries quickly.

4. Resists scratching
The material resists scratching even when rubbed with steel wool, indicating its excellent abrasion resistance.
