conrad taggart Posted September 18, 2021 Share Posted September 18, 2021 As per the above I have a Hangar 9 tango where the covering film is beginning to lift on the elevator edges. What is the best way of securing this ? The old film seems to have lost its adhesion. Many thanks C Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted September 18, 2021 Share Posted September 18, 2021 Deluxe Materials Cover Grip will do the job for you. It's heat activated - just put a little on the underside of the lifting film edge, let it dry for a while, then iron it down. Quote Link to comment Share on other sites More sharing options...

We don't know the circumstances under which it's being used. They scoffed at Deluxe's offer to provide a replacement, but surely the first recourse would be the retailer if the particular product was defective? Maybe consumer law is different in the Land of the Free to be ripped-off. DLM was started and is run by a couple of industrial chemists, so I assume they know what they are about...

leccyflyer Posted September 18, 2021 Share Posted September 18, 2021 I've used Cover Grip many times, never had a problem with it and, like I said, it does the job. 1 Quote Link to comment Share on other sites More sharing options...
conrad taggart Posted September 19, 2021 Author Share Posted September 19, 2021 (edited) Will put some on order and give it a trial run first to make sure it goes off .... Leccyflyer does it cause problems when you come to recover over and above what you would normally expect. Mike T don't think the problem was the cost of the product or it not working which was rather minor relative to the subsequent problem and damage it "did", hence their reaction.

leccyflyer Posted September 19, 2021 Share Posted September 19, 2021 I've no issues whatsover with Cover Grip - have used it to glue down lifting edges and on my spare E-Flite Mini Edge 540 used it to reattach the "sunburst" style trim film finish on the wing and tail surfaces, which had all curled up and come off due to being hung up for long term storage. I've definitely not had an issue with it failing to "go off" it dries to the desired tacky state in about 20-30 minutes. I wonder whether those having an issue slathered it on like mayonnaise and live in a climate with 90-100% relative humidity? 1 Quote Link to comment Share on other sites More sharing options...
Engine Doctor Posted September 19, 2021 Share Posted September 19, 2021 (edited) Definitely the best film adhesive imo was Clearcote made by solarfilm but since its demise DM cover grip is the next best thing. It would be great if DM could come upwith a Clearcote equivalent that was solvent based;not happening possibly due to our ott " can't do this , can't have that " woke health and safety regulations . The not drying issue could be caused by the presence of old adhesive as used on the self adhesive covering we experienced some years ago or some other contaminant. Certainly very high humidity would hinder the drying. Edited September 19, 2021 by Engine Doctor 1 1 Quote Link to comment Share on other sites More sharing options...
Jason Channing Posted September 23, 2021 Share Posted September 23, 2021 Ora cover heat adhesive is very good and works better than cover grip solvent based and dries very quickly this also works very well on contaminated surfaces etc . however its not cheap.

Eric Robson Posted September 23, 2021 Share Posted September 23, 2021 Is your Hanger9 Tango electric powered or glow? If it is glow and you have fuel contamination on the film and balsa it would need to be stripped and the contamination removed, otherwise it hill be very difficult to make it stick. Another quick fix is to clean it off and used Sellotape. Quote Link to comment Share on other sites More sharing options...

Judging by their website that is still working and dated 2021, you'd think that nothing had happened to the company if you were unaware of recent events. I doubt if they get many sales via collection from their premises - an odd situation - is the company kaput or not? Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted September 23, 2021 Share Posted September 23, 2021 I bought some Solite and a few tins of Clearcoat from Andrew back in February. He said that they had plenty of Clearcoat in stock, although I don’t know how old the stock is! Quote Link to comment Share on other sites More sharing options...
Trevor Posted September 23, 2021 Share Posted September 23, 2021 I’m a bit late on this one, but if it’s just the edge of the film lifting, I sometimes just smear PVA under the lifting edge, let it dry then iron the film down. You will have a bit of PVA residue to clean off the iron afterwards though! Disclaimer: I’ve only done this with gliders and electric models - oily applications may need additional fuel proofing.

Even part full tins keep well unlike some solvent based paints the clearcote doesn't seem to absorb water so tin doesn't go rusty and discolour the clearcote unlike dope etc. Quote Link to comment Share on other sites More sharing options...

Bruce Collinson Posted September 24, 2021 Share Posted September 24, 2021 It's possible not everyone knows this, I didn't until I was told, but to keep all such materials airtight, invert the tin after closing so it forms a seal. + 1 Clearcote although I sometimes cheat and use Hard as Nails on leccy stuff.

Like the idea of this as I have noticed the bit I have the most trouble covering is where the exhaust could dirty with fuel. Couple of questions if i may ... Does it work with a wide variety of covers or just their own ? "Our liquid adhesives are an exact match to the adhesives used for our covering films. Accordingly, always choose the adhesive appropriate for the covering film you are using" https://www.nexusmodels.co.uk/oracover-heat-activated-iron-on-adhesive-0960-100ml-tin.html Plus does anybody know what an appropriate thinner would be - hopefully not proprietary "In case our adhesives have dried out a bit in an opened tin, you can restore the original viscosity by adding the appropriate thinner."

Ace Posted September 30, 2021 Share Posted September 30, 2021 Hi-tec thinner for Balsaloc, Covergrip & PVA = any very expensive spring water or as a honorary Yorkshireman (that's a Scotsman with the generosity squeezed out ?) - tap water. I to would be interested to hear if the German chemical industry's Oracover truly required something different or just marketing ? Quote Link to comment Share on other sites More sharing options...
