New fast-cast resin that was developed specifically for adding color pigments and fillers to achieve true color representation or filler effect. Small amounts of pigment will yield accurate, vivid colors from cured castings. Vacuum degassing is not necessary. Convenient one-to-one mix ratio (one part A to one part B by volume). The differences between them are pot life and demold time. Fully cured castings are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for Smooth-Cast Liquid Plastics include reproducing small to medium size sculptures, cold cast bronze castings, making prototype models, roto cast pieces, special effect props, and decorative jewelry. Net weight 32 oz. (909 grams).

Technical Information: pot life: 2.5 minutes, demold time (depending on mass): 7-10 minutes, shrinkage: .01 in./in., viscosity: 100 cups, S.G. g/cm3: 1.07, S.V. cu. in./lb.: 27.7, ultimate tensile strength: 3,170 PSI

I use casting plastic to make masks and I ordered this by accident instead of Smooth-On 300. The difference is this plastic has a longer curing time, and even when you de-mold it, it was very soft and malleable for a long time. It did harden stiff overnight, but the long cure time caused me some warping problems. Keep in mind, I was used to the 300 series which cured hard in two minutes, so while this did not suit my needs, it is still a good product, and may suit your needs well. If you do not dye this plastic ,it has a frosty, glow-in-the dark look about it, but it does not glow.

Great casting resin that yields a sturdy product upon demolding if appropriate cure time is allowed. Colormatch resin kit allows for ensuring a variety of resin colors with various levels of intensity depending on coloring agent used.

I cast model resin parts. I was looking for a better but cheaper resin then Alumilite. Let me tell you, this was the cheapest place I found for this resin. Very great product it is as well! Works very well. The shipping was fast too. I am 100% satisfied with both the product and the supplier. I most certainly will buy again!

Ok folks.. here it is.. remember the flower making craft years ago where you took wire & dipped it in a liquid plastic solution? It formed this plastic type material that made these individual petals. Well this is it! As well as it's orginal purpose. I have made wonderful wings.. Huge flower Petals! Gorgeous stage props. Try it.. you won't be disappointed!
