Water and Oil Repellency

The stickiest food, the most viscous oil will struggle to adhere to fluorine-based materials. The ability to repel water, oils and dirt is probably the most famous properties offered by fluoro-based resins and coatings. Beyond the well-known non-stick properties used in cookware, their low coefficient of friction and inherent hydrophobicity pave the way for stunning usages.


Why are fluoropolymer non-stick and repellent?

Fluorochemicals have smaller attraction forces between molecules (the cohesive energy between the molecules) because of the stable C-F bonds.
It generates a low surface tension. On the other hand, water and oil have a stronger cohesive energy between the molecules, and the molecules attract one another, leading to high surface tension. Liquids are repelled because the attraction force of the liquid molecules is stronger than the treated material and form a droplet.
Microorganisms and other organisms are less likely to adhere to the surface of a fluorine material. In the case they would, they usually can digest fluorine materials slowing their growth.

Increase processes productivity

In production processes involving fluid handlings or demolding, significant improvements can be brought by materials having a lower coefficient of friction.
- Increased release rate of fluid containers (liners, coatings)
- Lowered use of lubricant for friction component (gears)
- High precision mold release and limit parts default
- Reduce residue in mold and consequently mold cleaning

Extend electronics life service

One of the main reasons for electronic failure is corrosion. When the assembly breaks, humidity penetrates. It can be avoided with a hydrophobic conformal coating preventing moisture from attacking component.

Innovate with self-cleaning surfaces

Maintaining a clean aspect longer and repulse dirt is a game-changing benefit for many consumer goods application:
- Transparent or shiny substrates such as touchscreen or faucets become fingerprint free
- Buildings cladding and external films are self-cleaning
- Cookware is easier to wash even after burnt grease
- Textile and carpet resist to liquid spill and are easier to clean

Improve patient comfort

The low energy surface provided by fluoropolymer naturally help the healthcare field:
- Single-use repellent apparels protect patient and staff from bodily fluids
- Wounds are kept dry thanks to waterproof bandage
- Drug delivery system advance a more consistent and precise transfer
- Biocompatibility of implants is improved thanks as biofilm hardly adhere and can't grow
