Hi Members,

I am looking for suggestions for favorable Glue for Depron.

I am trying to make the Fuselage with the technique used by Experimental Airlines.
The method he showed was to use Glue Gun. But When I try it, the Glue gets cold by the time I get sufficient Glue on the board. Hence no go here.

Then he suggested to use White Gorilla Glue. This Glue is not available in India. I got an old stock of brown Gorilla Glue, works well but the glue is very thick, now I have to finish it quick. Does anyone has experience on Brown Gorilla Glue, how to dilute it? The normal paint thinner does not seem to work.

My Experiments with Glue :

Normal CA eats away the Depron.
Tried Fevikwik, results same.
Tried Fevibond completely dissolved the depron.
Glue Gun is excellent but cools down extrmely fast.    Seems that I need two People with Glue Gun to get a lot to Glue on the 4 feet strip.

I did some search on our forum and found a lot of hints from the various discussions on Glue.

Few suggestions were in favour of  the following brands :

Fevicol Decorative Glue.
Hard to get it in normal shops in Bangalore. Might have to look online stores.

Foam Safe Evotite CA Glue.  : Is it safe on Depron? Where do we get it?

Bondtite   Is it safe on Depron? Where do we get it?

Araldite  Is Araldite Depron Safe. Will the normal flavour of Araldite work?

Araldite instant clear Is it safe on Depron? Where do we get it?

White Gorilla Glue This works for sure. Can we get it locally?

Hot Glue  Excellent but will have to buy another Glue Gun and request a colleague to help getting sufficient glue on the surface 

Suggestions are highly appreciated.

Buddy, epoxy [araldite] is the best bet for most bondages, but the only draw back is the curing time which is 5-8hrs. But once set, its hard [if not impossible] to break the bondage.

There is a quick set [5mins] of araldite, but the bondage is quite rubbery and not very strong as the standard one. Good for non structural and rapid fixes.

And for Fevicol Decorative Glue, why not use just dial to find out who vends it in Bangalore, hardly anything that isnt available here.

Hot glue and fiberglass tape works well together with depron.
adds a little weight though.

Thanks Ashok.

Thank You Ashok P.   

So I believe this will be the normal Araldite that is available over the counter?
5-8 Hours curing is not a bad trade off when it comes to importing costly Gorilla Glue. 
And who knows it is the same chemical cheaply available in India but we don't know the local name so we are drooling for imported maal  .
(This is why I wanted your suggestion and got it  )

Most of the things are manageable by Hot Glue Gun but only this fuselage is giving a little challenge.

Worrying of my Stock Gorilla Glue, I destroyed the bottle to take out the glue

How do I dilute this one. Willing to keep it for sometime

Fevicol PUR 1K This exact same as Gorilla glue. If you can mange its local source.

Polyurethane? If the same base as the PU paints that are used for auto paints, then the thinner and hardner from the paint shops should help us to thin to required viscosity too I believe.. Wondering what 'moisture curing' means!? Thanks for the info sundaram sir..

Same like Gorilla glue cures when it come in contact with moisture. I don't think you can use thinner for thinning.

So moisture is a must or an additional feature? Will definitely get one tomorrow and try out for sure.. thanks again

Moisture Atmospheric is enough. But to speed up additional may be induced but too much makes very Foamy and porous brittle week joints.

Sir , what's Fevocol pur 1k's cost ?

I have not been able to buy one till date Devang. 

Google will give you a rough idea.

If you are finding it difficult to work using hot glue, try 5 min epoxy. It's the second best to hot glue in my opinion. Another wonderful option is to tape the area to be glued using packing tape and then use Fevibond.

Foam Safe glues too work well with Depron.

It doesn't really harden as much as an epoxy. Rather it stays slightly flexible which makes the joined/repaired portion strong to future impacts and crashes.
If it is hard and solid, a crash could crack the glue up instead.

So many responses in less than 24 hours. I am touched.   


Fevicol PUR 1k is same as gorilla glue. Is it transparent while or Brown? I was preferring White one.

@VishalRao : 5 Mins Epoxy is there a brand particularly. If you could post the image.

Fevibond...!  No No it dissolved it the depron in testing.

@IndianHobbyShop : Will give it a try.

I got nice inputs. I couldn't thank much.

5 Mins epoxy brands: Fevitite Rapid, Araldite Clear, Bondtite

Fevibond: I guess you did not read my reply properly. You can apply packing tape to the area to be glued and then you can apply fevibond. This way, fevibond will not come in direct contact with depron.

+1

Yes Vishal, the packing tape Idea would be nice. No Direct Contact with Depron and can be pulled out when needed. And I know that Fevibond is very forgiving.

Err... Ahem....Well..... This way I could use any glue that does not dissolve my packing tape and holds it together.

So there is no need to run after Foam Safe Glue. You solved the root of the problem in one go.....

Guruji, you are quite experienced.  +infinitive for creativity.

Awsome ....   !

Cheers!

Well, Fevibond isn't that forgiving. Once set, it'll not come off easily. However, you get plenty of time to align the surfaces and realigning also is fairly easy if there's some mistake.
