89 Araldite MT 35600, Araldite MT FST Benzoxazine resins Araldite MT Description!! Bisphenol-A benzoxazine resin Typical characteristics!! Aspect: yellowish solid!! Melting point: C!! Viscosity at 125 C: mpa.s Main features!! Di-functional thermosetting molecule!! Reacts at high temperature through addition reaction, without gas release and with near-zero shrinkage!! Creates on curing a phenolic-type network, showing very low moisture absorption!! High glass transition temperature and high modulus network!! Compatible with various other chemistries including epoxies, bis-maleimides, phenolics# Applications and benefits!! Provides matrices with higher modulus than epoxy resins, with equivalent glass transition temperature, lower water sensitivity, and better flame resistance!! Proposed for advanced composites, structural adhesives, laminates for printed wiring boards, high performance coatings, encapsulating and molding compounds Advanced Materials 89

90 Araldite MT 35600, Araldite MT FST Benzoxazine resins Araldite MT FST Description!! Bisphenol-F based benzoxazine resin Typical characteristics!! Aspect: yellowish semi-solid!! Viscosity at 100 C: mpa.s Main features!! Di-functional thermosetting molecule!! Creates on curing a phenolic-type network, showing very low moisture absorption!! Medium glass transition temperature and high modulus network!! Compatible with various other chemistries including epoxies, bis-maleimides, phenolics# Applications and benefits!! Provides matrices with higher modulus than epoxy resins, with equivalent glass transition temperature, lower water sensitivity, and better flame resistance!! Proposed for advanced composites, structural adhesives, laminates for printed wiring boards, high performance coatings, encapsulating and molding compounds!! Offered higher structural properties and safer handling than phenolic resins Advanced Materials 90
