Epoxy systems for applications below zero degrees celsius

摘要

Epoxy based products are finding increased utility in a wide variety of structural and electrical applications that are required to operate in low temperature environments. This versatile polymer offers many attractive features such as high mechanical strength, outstanding dielectric characteristics, excellent adhesive properties, very good chemical resistance and excellent thermal endurance. Such features make them materials of choice for high and medium voltage electrical apparatus that operate in below zero Celsius environments. At lower operating temperatures, many factors come into play affecting overall performance. Among these factors are: speed and effectiveness of cure, fracture toughness characteristics, and thermal expansion properties.
