INSULCAST 3230 LV is a low viscosity, highly filled epoxy formulation that in addition to excellent electrical properties, has unusually high thermal conductivity, with low thermal expansion – similar to INSULCAST 140FR, but with lower viscosity. This system meets NASA outgassing specifications, with tolerances for TML ranging from 0.40 to 0.41% and for CVCM ranging from 0.0 to 0.1%..
