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® 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.
