Flexible epoxy in curable tape form

The curable epoxy tape hereafter referred to as Fibremat V was developed primarily for the insulation of form-wound coils. Fibremat V i provides a tough insulating sheath with resistance to most commonly encountered chemicals and solvents, and will retain mechanical and electrical integrity in excess Of 75,000 hours at 130°C as determined by curved electrode tests. The flexibility of the tape before and after cure permits its use in high speed rotating equipment where a more rigid resin would be subject to cracking from vibration and distortion. In the highly cross-linked cured form, the resin is resistant to water, brine, dilute acids, aliphatic hydrocarbons, and some aromatic hydrocarbons. The resin is subject to attack by strong bases, and is swollen by ketones, esters and aromatic hydrocarbons.
