Smooth-On Free Form™ AIR

Generic Family: Epoxy; Epoxide • Supplied by: Smooth-On, Inc
Free Form™AIR is an extremely lightweight epoxy putty suitable for an infinite variety of industrial and art-related applications. This is a low-odor, low shrinkage putty that is unique, inexpensive and easy to use. Free Form™AIR is mixed by hand with a 1A:1B by volume mix ratio. It offers a long working time and cures overnight at room temperature to a hard, rigid epoxy that is very strong with modeling board-like properties. Cured Free Form™AIR is so lightweight, it will float in water. It can be sanded, shaped, drilled, tapped and CNC machined/routered. It will readily accept any paint. Free Form can also be color pigmented with SO-Strong™ or Ignite™ colorants.

After mixing, Free Form™AIR can be pressed into a mold to make a lightweight, detailed casting. It will hold vertical surfaces and can be applied to almost any surface including polystyrene foam for rough sculpting. Free Form™AIR putty can also be used to make rigid support shells or mother molds.

Epoxy Laminating; Laminate Free Form™AIR putty in between layers of EpoxAmite™ Laminating Epoxy and fiberglass cloth, carbon or other fiber for making lightweight composite parts. Eliminates the need to make multiple layers of laminating with liquid epoxy; saves time and labor. Epoxy Tooling Applications - use as a filleting material. Also good for jig and fixture construction.

Used as a lightweight adhesive, Free Form™AIR will bond to itself and a variety of surfaces including wood, stone and EpoxAcoat™ Red surface coat epoxy. Free Form™AIR will even cure under water.

Pot Life/Working Time; this material is mass sensitive. The more material you mix at one time, the less time you have to work with it. Working tip; If mixing a large quantity, flatten putty with a rolling pin to reduce mass concentration and extend pot life.
