Foam-Tac is a type of foam-safe contact cement that is designed specifically for foam. Manufactured by Beacon Adhesives. It stays flexible after its dry, so it can be used to make hinges but it also works really well for general construction. It can be used on balsa and carbon-fiber as well as foam, and has many other uses as well.
The package contains SIX tubes. The tiny 5ml tube is perfect for making 1 or two repairs – break the seal when you need it. The tube has a fine tip for application prevision. This product is also available in larger 1-oz tubes or 2oz bottles.
