Material Notes:
TRA-CAST 3143 has a low viscosity and long pot life. It is certified to the requirements of UL 94 V-O, and is recommended for rigid potting, laminating, transformer encapsulating, filament winding and coil embedding applications where a desirable combination of superior mechanical and electrical properties plus fire retardancy and room temperature curing is required. This easy-to-use epoxy system has a low coefficient of thermal expansion, and exhibits excellent wetting and adhesion to most electronic and aerospace-industry materials (metals, glass products, ceramics, industrial laminates and many rigid plastics). Fully cured TRA-CAST 3143 is a durable electrical insulator, dimensionally stable over a wide temperature range, and is resistant to moisture, gases petroleum lubricants and fuels, salts, many mild acids and alkalis, and other organic and inorganic compounds.Information provided by Tra-Con Inc.
