Daikin America: Optool

Daikin’s Optool product line is a technology designed to create surfaces with resistance to fingerprint deposition as well as smudges, general fouling, and stains. Moreover, Optool acts as an easy clean coating facilitating fingerprint, smudge, and stain removal on a wide variety of glass, plastic, and metal surfaces. It creates a very low surface energy finish on properly coated substrates leading to extremely hydrophobic and oleophobic surfaces. Along with imbuing a surface with non-stick and easy clean properties, Optool also improves the (haptic) sensation of a treated surface.

As a modified PFPE (perfluoropolyether) nanocoating, Optool applied to a surface is transparent and yet produces smudge resistance, easy-to-clean, and anti-fingerprint properties. In addition, Optool coated surfaces have a smooth or slippery feeling to them. From a fundamental standpoint, all of this is due to the hydrophobic and oleophobic (what some call “omniphobic”) nature of surfaces coated with Optool. Finally, while designed primarily to generate oleophobic non-stick, easy-clean, stain and smudge resistant surface characteristics, Optool coatings are also abrasion resistant and UV durable thanks to the intelligent design of their polymer structures.

The Optool Portfolio
OPTOOL is a Daikin brand and product line that is derived from PFPE’s (perfluoropolyether) containing different functional groups that allow for covalent bonding of the fluoropolymer directly to a surface. Alternatively, Daikin also makes one grade, Optool DAC-HP, that can bond within a functional coating matrix when used as a coating additive.
