Material Notes:
TRA-CAST 3156 is an easy-to-use, low cost, versatile epoxy resin and hardener system developed for general purpose casting applications. It develops excellent adhesion to most metals, plastics, and ceramics, and is recommended for electrical and structural potting and encapsulating applications where the combination of good mechanical, thermal, electrical and room temperature cure properties are required. Fully cured TRA-CAST 3156 is a strong, tough, electrical insulator with high heat stability and a low thermal coefficient of expansion that provides successful performance over a wide temperature range. It is resistant to industrial environments that include water, weather, galvanic action, petroleum fuels, lubricants and solvents, gases and vapors, many mild acids and alkalis.Information provided by Tra-Con Inc.
