Product Description
Feather Lite™
Feather Lite™ is a heavily filled low-density urethane casting resin. Cured plastic is lightweight (it floats in water!) and has a much lower density than other casting resins.
Feather Lite™ features a convenient 1A:1B by volume mix ratio and mixes easily (pre-mixing of parts A & B is necessary). Cured plastic is strong and can be carved, machined, drilled, sanded, etc. Feather Lite™ can be pigmented with SO-Strong™ color tints prior to casting and finished castings can be painted. And because this product is low-density, it yields more plastic per pound/kg. than other casting resins, the cost per casting is low. Feather Lite™ can be used for a variety of art or industrial design related applications including reproducing sculpture, making fishing lures, prototype model making, casting doll heads and figures, etc.
EpoxAcast™ 655 + 101 Hardener
EpoxAcast™ 655 (formerly Metalset™ A-30) is a versatile aluminum filled castable epoxy resin that is very hard and strong. It is dimensionally stable, even when mass cast up to 512 in³ / 8,390 cm³.
