EkoBond is a revolutionary water based cement for the application of fabric. EkoBond has extreme bond strength for fabric to fabric and fabric to non-fabric surfaces in both peel and shear tests. EkoBond is very user friendly since it has very little odor and can be used in a closed shop with open flame heat with no health or fire hazards. When dry, EkoBond will adhere to itself, making it useful as a contact cement for a variety of applications. EkoBond is EPA compliant, non-flammable, non-hazardous and low in VOCs.

Available in quart or gallon-sized containers.

Great for patching fabric without damaging the finish like solvent based glues do.

I know Ekobond is a little pricey, but there is really no satisfactory alternative. I wish the competition would come out with something similar and maybe drive down the cost. WATCH Stewart Systems videos!!! Easy and safe to use. FYI, 1 quart should attach all fabric on a 120 square foot wing. You’ll need more to seal the weave. Great product, is worth the price.

If you use fabric, then you must use Ekobond, there is really no satisfactory alternative. Not cheap, destroyed if allowed to get too cold, but a little goes a long way

Very easy to work with. Different application style than the other glues. Watch the online videos. You wipe off the excess glue before heating. Done right it creates a very smooth application. Low to no odor which is a huge plus over other glues especially if applying in a garage next to the house. I really am impressed!

Q: Is this Stewart Systems Ekobond cement suitable to use with Dacron fabric?

Yes, the Ekobond Cement is suitable to use with Dacron Fabric.

Q: Is Stewart Systems Ekobond suitable for Ceconite?

Yes, the Ekobond is suitable to be used on Ceconite fabric.

Q: Is this Stewart Systems Ekobond product heat activated?

Somewhat. None of our products are technically heat activated. EkoBond is softened by heat and that allows the fabric to be pressed down into it. But it is not activated by heat. The heat is a temporary tack to hold the fabric, the wet glue going through the fabric and drying is the true glue joint. EkoFill is similar. Heat is not necessary to apply it. It can however, be softened by heat. That is useful for pressing down tape edges with an iron. Ironing tape edges down works equally well with Ekobond or EkoFill. Too much heat will make it smear or stick to the iron, so be careful. 200-250 degrees is good for that purpose.

Q: Can I use Stewart Systems Ekobond over a fuselage cover with enamel paint or do I need to strip it to bare metal?

Per Vendor: E610 will adhere just fine to any paint that is clean and scuff sanded. However, it is important to remember that it is adhering to the paint. If the paint does not have good adhesion to the substrate what is bonded to it will simply come off with the paint. As long as the paint is in good condition with good adhesion, no need to remove it.
