Anti-icing coating

Would you apply an anti-icing (ice will not stick to it) coating to your leading edges and prop?

It is a thin, brush on clear/translucent coating that would last 1 year and cost about $250. It cannot be used over boots.

Ed,

Will it work on the TKS panels and the wet prop?  If the product would be safe for the TKS system, I would give it a try.  Putting the product on the landing gear and tail would be helpful.

No, you cannot use it on a TKS system it would plug the holes. You can use it on the tail. I have to think about the gear.

Hi Ed,

Can you provide more information please? Is this something you are developing? What is the technology – silicone or others? Is there technical information with testing available?

Ed, I'd consider it but I would be cautious.  Would it still be obvious if you were picking up ice?  If the ice didn't stick, then might you be unaware that you were continuing in icing conditions?  I'd rather get out . . .

I developed this for the Military, like I did Rejex. The initial testing by the Military (helicopter and fixed wing) is excellent. This is all I can tell you now. I am scoping out the potential commercial market for a temporary ice rejection coating.

Ed,

The reason I am asking is because I have been working with a company in Florida on testing a compound that would do just that. Initial testing showed no ice adhesion to any surface covered with this compound. In addition, it can be applied over TKS panels and boots. It also has been tested by Boeing with passing all tests related to aircraft icing.

I do not know if it will ever be commercialized due to inventor’s eccentricity on how it should be supplied to the market and royalties amount that do not fit in any business model.

In general, I would spend $250 to cover all surfaces that are not protected by TKS.

Depending on demonstrated effectiveness, it could be an alternative to TKS.  Why would you restrict the coating to the leading edges?  I recall that one of the problems noted with the Thermawing is in certain conditions the runback refreezes on the wing behind the leading edge.

Sounds like it would be most suitable for SR20s that have no TKS,or 22s without TKS.I would gladly spend that a year.However,would it be owner applied,or would it have to be a shop job?

Does it contain silcone?  That would be a showstopper for the Cirrus fleet due to issues with adherence to the composites and paints.

Ed on the AOPA forum you state that it WILL affect Plastics (solvents).

I presume that would include plastic Cirri?

Hi Rick,

I do not believe you are correct in making assertion that silicon is a “show stopper”. There is absolutely no evidence that silicon is harmful to any part of Cirrus aircraft. Any silicone application can be removed with an 800 or larger grit sandpaper. As long as it is knows that silicone is used on Cirrus, any reputable shop can prepare surface properly for a good paint job or a repair.

May be you have additional information on this subject that would clarify your statement. It is my opinion that "fear of silicon" is an old wife’s tale.

Huh?  Checking page 8-25 of my SR22 POH under Cleaning and Care I find the following admonition: "Any good silicone free automotive wax may be used to preserve painted surfaces."

Now, maybe that evidence is not based on any evidence, but it is evidence to me that Cirrus Design wants to avoid silicone treatments on their painted surfaces.

No doubt that a knowledgeable paint shop could overcome the use of silicone, but why bother?  Wonder if there are issues with the underlying composite materials and not just the paint . . . ?

You paint it on where you would like it. When it dries ice will not adhere to it.

It does not contain any free silicones as most waxes do. When it is removed there should be no paint adhesion issues on the clean surface even before paint prep.

Rick,

 

Just leave a section untreated. If you see any ice buildup get the he*** out of there.

You cannot use it on plexiglas. You can use it on painted surfaces.

You can paint it wherever you would like, except on plastic like plexiglas.

OK Ed, how  and where do I get hold of this stuff ?

Charles

Based on the info given, yes, I would try it

The silicone wax thing is not a "showstopper".

I won't take any of Cirrus' advice on paint care so long as they continue to hose it on and sand it off and compound the fresh polyurethane within a day or two of spraying.  They don't even follow their own book recommendations iof washing with sopap and water.  Do they still use that range cleaner $hit that some local Duluth shill sold them on?

ALL knowledgeable painters will sand and prep using one of a thousand inexpensive silicone wax remover paint prep products.

And no, silicone will not damage the underlying "composite".  It is not a solvent and the "composite" is the same as (if not more durable) than every fiberglass boat afloat!

I'd be interested in what Ed has to offer.  There have been several Anti-Ice Coatings offered over the years and few worked.  If anyone can do it then Ed can!

How would this work if the leading edge were covered with protective tape, such as Aerotect? I believe the tape is made of polyurethane.
