EXPANDING ON THIS ISSUE.....  

I have a few RC friends in USA.
In America they use "Amazing Goop"; A very thin coat of this rubber based foam safe adhesive is also applied at leading edges of all foamies to prevent any nicks or hanger rash from spreading deeper and making the wing section weaker.. makes it heavier by 20 to 30 grams though.

We use mainly UHU Por which is a German product and Gorilla Glue which is a bit expensive but an amazing product..

UHU POR was in short supply but that is due to the price increase...
Its back in the market now ..
A small 20 gram tube that used to retail at Rs250 approx is now approx RS 400 ...


If one wants to fill gaps then best is Gorilla Glue..

As suggested by some one earlier in the thread, most CA adhesives are safe once the acetone has evaporated... the makers suggest to keep these cool...(in your fridge.. :) lol)

Might be a good idea to make a trip down to the PVC window and door frame manufacturers and buy a mitre kit from them which will have a bottle of CA and kicker (Accelerator for Cyanoacrylate)....see image below. Recently I bought a MX2 3D ready to fly from Hobby king and it was assembled totally using Cyanoacrylate... so just one adhesive can do most jobs but we aeromodelling tinkers like messing about and venturing into other fields to find better products...

Will Peditite fabric glue work on HD thermocole?
Based on earlier post it works on depron and EPP?

We have to unite and to prove ourself to make indigenous products as well as marketing / Canvasing them. I'm sure we must achieve success if we try unitedly.

I do not see why not as thermocole is same family as Depron or EPP...Expanded Polypropeline

Thermocole is EPO ...still Expanded Poly.....something so I do not see why it will not work...Try a small area.

EPP: expanded polypropylene (similar to expanded polystyrene but very flexible and has 'memory' so it bounces back to shape after being compressed)
EPS: expanded polystyrene (beer cooler foam)
XEPS: Extruded polystyrene (Dow blueboard) USED FOR BUILDING INSULATION

Good Luck..Deepak

Though costly, but wallpaper glue ( NaCMC or CMC ) can be applied over the thermocol to make coat. It is water soluable.

Well friends... we are making a big issue about the whole thing of what glue to use for foams.... The first post after Mr Anwar's thread question resolvs the issue to a large extent.  All we need to do is go and check these glues on a piece of scrap foam piece.  Ok... now... I have used fevicol both regular and marine for normal form i.e. thermocol and also used industrial grade epoxy (generally sold in seperate bottles of Resin and hardner from about 300 gm to a Kg.  The most common one available with hardware stores is Lapox).  Lapox costs roughly Rs 300 for the 325 gm bottles of resin and hardner set i.e. nearly half of Araldite.  One needs to mix the two in equal quantities for the epoxy to set in 24 hrs (can use slightly more hardner to make it set in about 6 hrs).  Hot glue is also good and extremly user friendly (Check www.ebay.in for good glue gun and glue sticks which are at upto 50% cost of most sellers of RC equipment in India.  I use it and guess you all can also use it easily.
Other things are Fibre tape (one can buy the silver fibre tape used by Air Conditioner mechanics generally Split AC guys.... they use it for covering the cooling tube joints), normal masking tape (you may cover the foam with thin paper.... sticking it with a thinned layer of fevicol and allow it to dry).  Thereafter the normal masking tape - brown tape fixes very well on the covered sheet.

GO ahead and improvise whatever you have... Happy Flying...

Yesterday tried some glue available in market

Fevibond used for tyre tube puncture.

Man ate whole foam

Fevicol tube .

Took more time to bond but safe for foam

Feviquick 5 rupees pack

Also ate the foam

Best was Fevitite Rapid(5min )Epoxy

cost just 15 rupees

white and red tube (make sure rapid mentioned on the blister pack otherwise don't get it)

Mixed both epoxy resins and hardener

White tube is Hardener and red tube is Resins excellent result just bonded in 5 min tried to separate the pieces but the foam broke not the bonded area.In Chennai we can get Resins and hardeners separate for 8 rupees

Don't get confuse am sure Fevitite Rapid is excellent for bonding foam

not sure if anyone mentioned this glue however ...for balsa to vegetable plastic bags  tried many glues dint work this one is the best  FEVICOL SR 998 suggested by seniors on the forum  :thumbsup: :thumbsup: once glued very difficult to separate in fact impossible.

Well..... I have always preferred the locally available fevicol over all other glue for blasa.  In face I used to use the glue after diluting it with a little of water to make it run.  This way it would so into the depth of the joint and the adjoining balsa grains.  Yes takes 4-6 hours to set.  So fix everything in the night before going to bed and next day afternoon when you are on the table it is bone dry.  Thereafter run the diluted glue again on the joint to double seal it.  allow it to dry and you have a perfect joint.  For places which take high abuse... and engine mounts..... use commercial epoxy. 
For emmergency repair of models use fevitite or other Cyno (superglue) and fibre and masking tape.  Never hurry through your construction.

After going through this thread, I noticed no one is using silicone sealant, the stuff they use to make aquariums. I have made a 3d background for my aquarium, out of desi thermocol and I used silicone to stick it all together. The stuff worked pretty well. Maybe applying too much will make the model a bit heavy, but so will hot glue.
My Sky Surfer is ready for assembly and I have pretty much purchased all the hardware and electricals. I have ordered Clear Foam Glue (Medium Cure) from Hobbyking but will have to wait until it arrives. 

kewal kalsaria

we can use pidilite foam safe glue...... only 25 rs.

anandp

@Kewal, if you can upload the picture of it, then it shall be easy for the members. Many times hardware stores don't know them by exact name, but by packing its easy to know.

I generally use this pedilite's fevi kwik 702 on elapor foam, but MRP is Rs.92/-... Is there any other product from pedilite
which is cheaper than this ? ( and foam safe! )

Can I apply Araldite on HD thermocol. Will Araldite eat themocol. I need some filler which can be applied on thermocol.
