Tra-Con Tra-Cast 3107 Low Shrinkage Epoxy Casting System

TRA-CAST 3107 is a versatile epoxy casting system developed for high performance production potting, encapsulating, casting and tooling applications where low shrinkage, easy handling and flowability, and excellent mechanical and electrical properties are required. This formulation has a good pot life and low exotherm properties, and cure at room temperature to a tough, rigid, solid with very low shrinkage characteristics and excellent dimensional stability over a wide temperature range. TRA-CAST 3107 adheres 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 which provides good resistance to electrolysis, leakage, and corrosion from water, weather, gases and vapors, and from chemical compounds including mild acids and alkalis, many corrosive salts and salt solutions, petroleum product and lubricants, and other organic and inorganic materials.
