Toray EX-1522
- Chemical Family
- Epoxy & Epoxy Derivatives
Toray EX-1522 is a high performance toughened modified epoxy resin system. The material displays both excellent mechanical and thermal properties, in addition to very low moisture absorption. EX-1522 has a flammability rating of V-0, which lends itself to usage in low flammability Applicationss. EX-1522’s ideal electrical properties make it a lower cost option for radome, antennas, and other critical electrical Applicationss. Finally, EX-1522 is an outstanding resin selection for use where self-adhesion to honeycomb without the use of a film adhesive is desirable. This resin bonds to honeycomb under vacuum or pressure cure and displays cohesive honeycomb failure during destructive testing. 177°C (350°F) Cure* Toughened Epoxy Resin System
