Free Form® AIR

Free Form® AIR is an extremely lightweight epoxy putty suitable for an infinite variety of industrial and art-related applications. This is a low-odour, low shrinkage putty that is unique, inexpensive and easy to use. 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.

Free Form® AIR is mixed by hand with a one part A to one part B 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 modelling board-like properties. After mixing, Free Form® AIR can be pressed into a mould 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 moulds.

Free Form® Air is a mass sensitive material with the pot life and working time. 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.

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 colour pigmented with SO-Strong® or Ignite® colourants.

Epoxy Laminating - Laminate Free Form® AIR putty in between layers of EpoxAmite® Laminating Epoxy and fibreglass cloth, carbon or other fibre for making lightweight composite parts. It eliminates the need to make multiple layers of laminating with liquid epoxy, which saves time and labour.

Epoxy Tooling Applications - Use as a filleting material. It is also good for jig and fixture construction.
