For someone that stripe own films: what kind of film cleaner you use BEFORE magnetic stripe the film? It's essential practice, any dirt residues on film may not allow the track to stick well. And, be careful, the cleaner doesn't have to be also a lubricating cleaner, it would make the situation worse, the track would slide off more easily.

Lubrication is, of course, good to do after the stripe.

Thank you. [Smile]

Hi Luigi,

I made some test with "Fuel Class F" (This is used to clean clothes, It doesn't damaged plastic materials, etc...).

However, Silicon oil is very, very difficult to clean out, so that, any material which has been contaminated with silicon is difficult to paint or to bond thereafter....

To be note I know somebody who made his own lubricating component (for films) using "Fuel Class F" (250Cl) mixed with 2 or three drops of Silicon oil.

It's true, Phil, Italian small format users use with success a product called "Avio" (I don't know if it has the same name in other Countries), and has a good degreasing result.
It should be the same as you indicate.
I was only wondering if there was an alternative.

I also know the formula with the addition of silicone oil, not bad as a solution, but only in the case AFTER stripe, it having a lubricating effect.

Luigi,

Before striping my films I only clean them using a cloth, no solution added. The stripe adheres fine. I apply FilmGuard after the recording process.

Hello Luigi. I read often on French forum about a product called "essence C". I couldn't find it in Belgium and it seems that's a local reference. So I looked for it in Paris but didn't see on the shelves. I asked (after sevral attemps in différents shops) and the seller went to the backstore to pick up a bottle. They can sell it but not display it, obviousely for safety reasons. This product removes the "grease" of the film and is advised to clean it. However it doesn't lubricate. It certainely exist in other countries under other names.

Thanks, guys, I happened to use both methods, only with dry cloth and with the degreaser.
Is that lately my stripe no longer works like a time, the main band keeps, but the compensation band comes off.
Since it worked very well before, it could be that the solvent has become old (I've had it for some time) and it has lost its function, or the reels of bands have been too old (I have for many years).

Doug what kind of glue are you using? Where can one obtain it?

Posted by Graham Ritchie (Member # 559) on August 19, 2018, 12:12 AM:

Jim

Its been a long time since I did my own striping but am pretty sure I used Trichloroethylene 100% for cleaning the edge, going over it twice before striping.

All I can say for sure, that the stripe is still hanging on after 40 years.

Kodak did produce a film cleaner 1.1.1 Trichloroethane which I understand is now banned.

However you could try Trichloroethylene which you can still buy in 100ml bottles from a chemist on a test film.

Cleaning the film edge first is really important for the stripe to take.... [Smile]

Jim, I buy the glue from FFR Film:
http://www.ffr-film.de/index.php?page=band&language=eng
In Europe I seem to remember that there are other sellers that have it, but perhaps they are supplying from the same place.
Overseas I don't know if someone sells it.

Graham, I tried to re-buy the glue, let's see if that's the problem in glue that no longer works because it's old. Otherwise, I will try to find the Trichloroethane and clean. But it would be strange if that was the problem, my two striper machines (Bolex Weberling DS 240 and Juwel mini 8S8) have always done their duty.
Thanks!

Thanks Luigi, I will check them out I have very few films that have or need cleaning at least in my silent films.

Posted by Luigi Castellitto (Member # 3759) on August 19, 2018, 02:22 PM:

My pleasure, Jim. [Smile]

But I'll show you the page where there are "glue" and tapes for stripe.
Cleaning is another matter, for sound or mute films (before stripe, if you intend to do it) I think it's always very good Filmguard.

Stay away from Trichloroethylene - it is a known carcinogen!

Posted by Douglas Meltzer (Member # 28) on August 19, 2018, 07:12 PM:

Jim,

I buy the glue from FFR, just as Luigi. Please note that due to shipping restrictions, only one bottle may be ordered at a time.

That’s great guys plan on testing it on some scrap film I have before trying it on my pride collection. And will use Doug’s experience of cleaning with a dry clean cloth.

It figures the company is out of the office till 9-1-18

The best thing would be a slow ultrasonic cleaning with perchloroethylene. Machines for 35mm and 16mm are still around at numerous post houses, but 8mm is very rare to find.

For 8mm/Super 8mm film, I think Spectra Film and Video is the only place other than Film-Tech that has 8mm ultrasonic capability.

For 16mm film, numerous labs should be able to offer it for 16mm (just make sure they are using perc and not HFE/Novec).

Post-striping, FilmGuard will keep the stripe from suffering any wear during projection.

Posted by Jim Schrader (Member # 9) on August 21, 2018, 08:31 PM:

Brad, is cleaning with ultrasonic capability at spectra film a job one sends out?

Posted by Luigi Castellitto (Member # 3759) on August 22, 2018, 05:23 PM:

Jim, I saw now that FFR is closed. In September I will also make an order about film striping. [Smile]

Brad, I confirm that Filmguard also "helps" the audio sector, the film run smoother and the strip is more protected.

Posted by Brad Miller (Member # 2) on August 22, 2018, 06:50 PM:

Jim, yes you would send your film to them to have ultrasonically cleaned.

We also have the capability at Film-Tech, but are in the process of moving offices over the next several months, so we likely won't be taking any kind of orders during the move.

Posted by Jim Schrader (Member # 9) on August 23, 2018, 07:54 AM:

ok, Luigi keep me posted i will keep checking back with the site in September.
