| TRA-CAST 3109 is a versatile epoxy casting system developed for solvent-free production casting, potting, encapsulating, and coating applications where low cost, easy handling and flowability, and excellent mechanical and electrical properties are required. Color coded for easy mixing and pouring, this formulation cures to a tough, rigid, low-shrinkage solid in a matter of hours at room temperature and is dimensionally stable over a wide temperature range. TRA-CAST 3109, with its good exotherm, pot life and pouring characteristics, is especially suited for large mass (up to 1 gallon) castings, as well as for other industrial and electronic large-pour applications. It develops excellent adhesion to rigid plastics and laminates, metals, and ceramics, has a low coefficient of thermal expansion, and is readily machined and shaped with ordinary shop tools. The fully cured epoxy system is an excellent electrical insulator and is compatible with electrical components, has good resistance to water, weather, gases and vapors, and from chemical compounds including mild acids and alkalis, many corrosive salts and salt solutions, jet fuels, petroleum product and lubricants, and other organic and inorganic materials.
