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.

Free Form® SCULPT is a two part sculpt-able epoxy clay that requires no firing and will self-cure in a short time to an extremely hard and durable state with virtually no shrinkage. SCULPT is 30% lighter than similar products and holds vertical surfaces better. Users can sculpt larger, stronger pieces with more control over weight distribution. Free Form SCULPT has an ultra fine particle size that gives the user the ability to sculpt finer detail with better precision using tools or shaping by hand.
Parts A & B are mixed in equal amounts by hand. Working time is a long 1.5 hours and Free Form® SCULPT cures overnight to a hard, rigid epoxy that is very strong and waterproof. SCULPT is easily colored by adding SO-Strong color tints to create marble or other effects. Cured putty is easily painted with acrylic paints.
Free Form® SCULPT does not contain crystalline silica (which is a known carcinogen). It can be safely sanded, shaped, and painted.
Used as a repair adhesive, Free Form® SCULPT will bond to itself and a variety of surfaces including wood, metal, glass, stone, and concrete. Free Form® SCULPT will even cure under water.
