Hi,
Guys I found the alternate glue for Gorilla glue. 1K PUR from Fevicol is the best alternative to stick depron or any other foam.

It's easily available in the market.

After a long time I found this. Felt really happy.

Lovely, thanks for the tip off.

So it will not eat Foam like Fevicol HEATX ?

how much time it will take to stick two parts ?

No It will NOT ... It is a "Filler" Glue which first expands on contact with Moisture then cures. If you put this between joint and tape the open ends, it penetrates well inside the open cells of     foam and provide best adhesion. There used to me smaller pack of similar glue from Mitelock called "Tough bond" but I dont see that in hardware store

Hi. Finally it is time to quit using Hotglue on our foam models(also on balsa). Our legendary Fevicol has released their own product based on polyurethane which is named as fevicol xpers, It may be depron or any foam kind this adhesive bonds the foam no matter what, it is absolutely "foam safe" too because it does not contain Acetone or cyanoacrylate which eats foam. i have made 2 models with it, this is 10x times more stronger than hotglue and impossible to separate the glue joint once bonded between the foam. Fevicol xpres is an best alternative to gorilla glue where 60 gram is sold for 800rs in amazon.in fevicol xpres is sold just for 500rs-500gram. There is no better PU glue in Indian market than xpres. hope everyone will use this glue on their future builds. bonding time is 15min yeah you need to wait. but it is totally worth waiting for the bonding time. the glue also fills any gap between the joints as it expands while drying. This is for sure the best alternative for hotglue because it does not damage your depron foam at the same time the weight of the hotglue on your model is totally eliminated. This glue is also perfect for balsa build.
