Free Form® AIR

说明

Safety – Use in a well-ventilated area (“room size” ventilation). Generally, if you use any epoxy system on a regular basis, wearing a NIOSH approved respirator is advised. Wear safety glasses, long sleeves and rubber gloves to minimize skin contact. Wear nitrile or vinyl gloves only.

Preparation – Materials should be stored and used at room temperature (73° F / 23° C). This product has a limited shelf life and should be used as soon as possible. Mixing should be done in a well-ventilated area. Wear safety glasses, long sleeves and rubber gloves to minimize contamination risk. If making a 2 or more piece mother mold, apply appropriate shim apparatus to rubber mold exterior.

Because no two applications are quite the same, a small test application to determine suitability for your project is recommended if performance of this material is in question.

Applying A Release Agent – For releasing epoxy from non-porous surfaces such as resin, metal, glass etc., use Ease Release 200 or 205 (available from Smooth-On) to prevent adhesion.

This product is mixed by hand. You must wear gloves when mixing this material, wearing vinyl gloves reduces inhibition risk.

MIXING & MEASURING - Free Form™AIR putty comes as two parts. Dispense equal amounts (golf ball size, for example) of Part A and Part B. These products have a limited shelf life and should be used as soon as possible.

Mixing - Knead parts together aggressively to a uniform color and apply quickly to surface of tool or mold.

Applying – Mixed Free Form™AIR is a dough that can be applied up to 1.5” (3.81 cm) thickness. Mix only enough Free Form to be used at one time. Free Form™AIRwill bond to itself.

Laminating - Free Form™AIR can be used in conjunction with EpoxAcoat™ surface coat and EpoxAmite™ laminating resin to create a strong and lightweight composite tool or mold.

Use as a Sculpting Medium - Free Form™AIR can be applied to wire mesh armatures to create rigid forms for sculpting. Wire mesh for sculpting is available at most art supply stores. Free Form™AIR can be applied to polystyrene foam to create a hard, rough-sculptable and sandable surface. When applying to polystyrene foam, maximum thickness is 3/4” (1.90 cm).

Smoothing Surface – Epoxy surface can be smoothed with water or isopropyl alcohol.

Painting – Cured Free Form™AIR can be painted and / or primed and then painted with acrylic enamel paints. Let paint fully dry before putting part into service.

Cure Time - Refer to specified Cure Times in the Product Overview section at room temperature depending on mass. Cured material will be hard and unable to penetrate with a finger nail. Cured epoxy can now be dry sanded. If machining or sanding, wear NIOSH approved mask to prevent inhalation of particles. Pot Life and Cure Time values are dependent on mass and mold configuration, as epoxies are mass-sensitive.

Heat Resistance – Fully cured putty with a minimum thickness of ½” (1.27 cm) will resist temperatures up to 140°F/60°C.

Removing Uncured Free Form™AIR Epoxy Putty - Remove as much uncured material from the surface as possible. Clean any residue with soap and water. Optional - Use E-POX-EE KLEENER™ available from Smooth-On.
