Abatron AboCast 8502-7/AboCure 8502-7 Colorless, Low-Exotherm Epoxy Casting Compound
Categories: Polymer; Thermoset; Epoxy; Epoxy, Cast, Unreinforced

Material Notes: AboCast 8502-7/AboCure 8502-7 is a rigid, heat cured, colorless, low-exotherm epoxy casting compound for larger masses. It is a 2-component structural and dielectric liquid system with extremely low shrinkage. It represents the highest level of thermal, chemical, and physical properties available together with colorlessness, lowest shrinkage, and low viscosity for easy casting. Very large, massive 8502-7 castings can harden in several days at room-temperature, or very slightly above it, for best colorlessness. This system also offers the best dielectric properties. Suggested Uses: Transparent Casting, Embedding, Encapsulation, Potting, and Bonding. Casting display or experimental models. Precise reproduction of anatomical or scientific models. Embedding organic, geologic, or metallurgic specimens for commercial or scientific uses. Encapsulation of electric, radioactive, or delicate components. Preservation or repair of artistic and historical objects. High-performance transparent table tops.
