Product Description
Free Form™ AIR HT
Free Form™ AIR HT is a low density, lightweight epoxy putty that offers high temperature resistance to 300°F/149°C when cured at room temperature and 400°F/204°C when heat post cured. This is a low-odor, low shrinkage formula that is easy to use. Free Form™ AIR HT is mixed by hand with a 2A:1B by volume or weight 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. It can be sanded, shaped, drilled, tapped and CNC machined/routered.
EZ-Spray™ FlexFoam
EZ~Spray™ FlexFoam is a flexible polyurethane foam compound that can be conveniently sprayed using Smooth-On’s EZ~Spray™ Junior System. EZ~Spray™ FlexFoam consists of two liquid components in an EZ~Spray™ cartridge. When combined in a mixing ratio of one to one by volume, EZ~Spray™ FlexFoam quickly cures to a solid, lightweight and durable 7 lb. (approx.) flexible foam, that can be used for a variety of special effects and industrial applications. Refer to Smooth-On’s EZ~Spray™ Junior manual and video before using.
