Our Technology
“Sputtering is akin to spray coating a film at a molecular level, yet it is so much more complex than described.” – Lee Boman. Director, Palo Alto Advanced Technology Center, Eastman Chemical Company, on the Magnetron sputtering process used in V-KOOL Solitaire Series window films.
The Science of Sputtering
In engineering terms, sputtering is the removal of material from a solid target by energetic ion bombardment in order to coat a substrate with the sputtered target material. A high voltage is applied to the target, which induces an electric field. The electric field energies the gas particles (usually argon) in the sputtering chamber, creating a plasma. These highly energised gas particles bombard the target with such high momentum that it causes atoms from the target to be dislodged and deposited onto the substrate (film).
Engineered in the heart of Silicon Valley with proprietary XIR technology, V-KOOL Solitaire Series window films form the core of our product range. Its proprietary XIR technology comprises precise stacks of metalised layers to form a protective film that reflects selective infra-red wavelengths. This spectrally-selective property makes a world of difference in window films, even to the naked eye.
