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.

this is one of the best news i heard in years , most welcome product
Not so user-friendly though. 1. After each use, the nozzle gets badly blocked 2. The glue when cured has a foamy appearance and looks bad
Tried it, went back to Fevicol SH ! Uncomplicated and solid
Will surely try it out. Have recently received a stock of Depron and have many plans awaiting construction.
