Eager Polymers EP4101 Castolite AC
- Chemical Family
- Polyesters
Eager Polymers EP4101 Castolite AC is a room temperature cured, air-inhibited, rigid, water-clear casting resin. The liquid color is pale turquoise to clear, however when properly cured, EP4101 is crystal clear with excellent sparkle. EP4101 is widely used to make clear paperweights, jewelry, crystal balls, or to encapsulate dried biological or botanical specimens. When used with fiberglass fabric, vandal resistant windows or resin-stained glass can be made. Eager Plastics' extensive line of transparent dyes are available for a wide variety of effects.

Typically castings should be poured 1/4"-1/2" thick maximum. Castings poured thicker than this are subject to overheating due to the exotherm. Results may be cracked, browned castings.; If using Eager Polymers' P-series silicone or polyethylene molds, no release agent is needed for casting polyesters. If casting into any other materials (urethane, metal, gel-coated fiberglass, epoxy, etc.), it is best to first layer a few coats of release and buff them smooth. Then brush a thin coat of PVA and allow it to completely dry before casting.; When curing, polyester resins often give off heat. For this reason, EP4101 should be cast in layers no greater than 3/4" to avoid overheating of the casting. Overheating can cause browning and cracking of the cured casting. If large castings are desired, our line of water clear urethane casting plastics can be poured up to 18" thick.
