Hard-flexible 2-component polyurethane casting compound with excellent electrical and mechanical properties. Due to its high impact strength and good resistance to water, transformer oil, gasoline, and other chemicals it is well suited for the insulation of low voltage components as transformers, coils, electronics switches, capacitors
and others.
The casting compound is UL 94 V-0 recognized as self-extinguishing having an RTI of 130 °C (UL file 302173, mech. + electric.). Also, it fulfills the requirements of the Household Appliances Standard IEC 60 335 having GWFI of 960°C and GWIT of 850°C and the fire test to railway components NF F 16-101 in the F1 / I3 classification. It complies with the RoHS (2002/95/EG) and electronic waste regulations (2002/96/EG WEEE directive of the EU).
