Permanent Anti-Fog Coating ............

[Chris Ryser]

I came up with a new coating that I would a few OptiBoard Members to try out. Any volunteers please contact me at oms_optical@yahoo.com , but please mark it on subject: line so it wont go into the trash folder.

Anti-fog coatings are known to get tired after a while and will not work anymore.

My new coating can be renewed by heating the lenses in microwave for 2 minutes, and they will work again like new.
(Do not heat the frame along with lenses.............just tried it and very thing went up in flames......so remove lenses from frame)

Atually it is not the same stuff without me knowing the Opticote stuff.

They advertise it as a :
Thermal cure process with dip hard coat primer and Fog Free coating, 2 day turnaround
TINTS cannot be coated at this time

My stuff is a humidity cure copolymer you can apply it on any surface you want and do it in about 5 minutes. The only condition is that your lens or coatings can take the heat in the microwave for 2 minutes and AR coatings can not be done as it would be covered by the coating and become ineffective.

I am still looking for any results from the ones that were going to test the product

I tried it on 2 pairs so far. I would say it cut the fogging down perhaps 50%. Though I don't have a source of steam in the office so holding it over a cup of really hot water might not have cured it properly.

The wetting is enough as you describe, but you do not say if you even did the next step, which was to wet the lenses again and then place into a microwave oven and heat at full strenght for 1 minute, only then the coating becomes 100% anti fog.

The question is really, once properly done how long do they stay anti fog, 2month or 4 month. Then they can be wetted again and placed in a microwave for 1 minute and they work again as before.

Got This in my e-mail today

Hey Chris, you sent us some anti fog solutions to try out a few months ago and I just wanted to give you a heads up. We tried it with four patients, and two have been extremely impressed with it. The other two fell off the face of the planet, it seems.

Actually it just happened that Canadas largest Safety Optical has started to supply it on lenses.

I´m looking for information about Anti fog coatings included in AR coatings, but I´m not found it. Anybody knows if it´s possible add this property in an AR Coating?

I make AR coatings with superhidrophobic in High vacuum systems and I would like to add this property in our process.

The product you are looking for does exist and is available as a concentratefor applicationm in the vacuum chamber or as a water based solution for an easydip coat operation as well as a by hand application that has renewable featureswhen the hydrophillic qualities are getting fatigued.
