I build exclusively with EPP. In the beginning I used Weders, I had issues with it turning Yellow and getting Brittle over time. Now I use Beacon's Foam Tac Glue. It works and acts just like Welders Glue but it does not turn Yellow or does not become Brittle! Give it a try! If you like Welders you will Love Foam Tac

Hey Bobby
Do you use it like Welders? Can it be used for hinges?
Thanks

Foam Tac by Beacon and Foam Cure by Bob Smith Ind. are very similar, in there application and both speed a build along significantly. However there are some notable differences.

1. Foam Tac seems to be more solvent based. Too much in a polystyrene joint and no place for it to vent or outgas and it will eat foam. Remains flexible after curing. It is a bit pricey.

2. Foam Cure does not attack polystyrene and it dries hard. Easier to sand if needed and is not flexible after curing. About half the price of Foam Tac.

EPP being a more flexible material, Foam Tac is the better solution. Also EPP is less susceptible to solvent adhesives and therefore holds up better to the curing process.

Polystyrene (aka MPF, FFF, XPS, Depron) is stiffer and does not need the flexibility of EPP is the perfect candidate for Foam Cure.

I use both materials along with Gorilla Glue White Formula. It all depends on the application.

I used Gorilla Glue quite a bit, (can foam up a bit too much unless the excess is wiped), but it was rather expensive here in the UK.

I found the Evo-Stik do a Polyurethane Wood Glue that works just about the same.

A search in your own areas for 'polyurethane wood glue' should find other alternatives.

Home >> GLUE & ADHESIVES >> Foam Safe Adhesives >> Flexible Foam Glue >> BSI Foam-Cure EPP Foam Glue - 4 oz. bottle
BSI Foam-Cure EPP Foam Glue - 4 oz. bottle


Item #: H-500
1BSI Foam-Cure can be used on Depron, EPS, EPP, XPS, EPO and many other types of foam, as well as carbon fiber and wood -- making it an excellent glue for RC planes. BSI Foam-Cure will not attack, melt or dissolve foams but holds quickly and cleanly. It remains clear and flexible once dry and does not become brittle.

Instructions for Use:

•ALWAYS test on scrap materials first to ensure compatibility.
•Surfaces must be clean, dry and free of dust and grease.
•Spread glue evenly on both sides of material to be bonded.
•Allow surfaces to air dry for 30 seconds to 10 minutes, depending upon size of area being glued.
•Press surfaces firmly together.
•Maximum bond is achieved in 12 hours.


Precautions:

•FLAMMABLE: Do not use near open flame or ignition source.
•Eye, skin and respiratory irritant. Avoid prolonged inhalation of vapors.
•Keep out of reach of children.
* Marked fields are required.
Qty*
Price $4.95

On EPP I have been using a product I get from WalMart called E-6000. Big tube, don't yellow and good price.

I honestly can't tell the difference between foam tac and foam cure. I was running out of foam tac and I ordered foam cure cause I just couldn't hit the buy now button on foam tac being 12 bucks for two ounces. In using it it seems the same to me. I don't know about being more brittle or not though.

I'm happy with it

For epp you can get a tube of beacon 3 in 1, it dries clear and works similar to the welders. Its what me and several of my flying buddies use. If you use the 40% off coupon on the hobbylobby website you can get it for about $3.50 a bottle. Shipping from them aint cheap but probably a store or two close by.

Foam Tac Hinges are made the same way you make Welders Hinges! For more info there is a Beacon Foam Tac Thread here in the Scratchbuilt Forum. You can also find good info on You Tube!
