Free Form™ AIR

Lightweight Epoxy Putty

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 colour pigmented with SO-Strong™ or Ignite™ colorants.
