Models like clay, works like wax. Self supporting without armature. Lightweight; 40% lighter than Plasteline. Medium grade for detailing and modeling. Non polymerizing, sulfur free. Is compatible with silicones and other rubbers. To Begin Castilene Soften with a variety of heat sources including heat lamps, hot boxes, crock pots, microwave oven, hot water or double boiler. DO NOT USE A DIRECT FLAME. Avoid heating above 210 F or air bubbles may result. Castilene can be melted and poured at 170-180 F. The strength and light weight of Castilene allows sculpting without a wire armature in many cases. Working with Castilene Hard Castilene remains malleable while working if kept warm by heat lamps, warm water, etc. All three hardness are compatible with one another. Hard Castilene can be used as an armature and soft and medium Castilene can be applied on top. Wax tools and wax carving methods are compatible with Castilene. Heat tools before carving. Chill Castilene to achieve optimum hardness for high detail and burnishing. Polishing and Finishing Castilene Use any wax dissolving solution including Goo-Gone, De-Solv-it, d-limonene or Prepsol based products, mineral oils and terpenoids to smooth the surface and polish with a clean cloth. Castilene does not inhibit the curing of silicone rubbers. Castilene can be burned out for lost wax casting.
