Araldite® MT 35600, Araldite® MT 35710 FST

Araldite® MT 35600 Description

!! Bisphenol-A benzoxazine resin

Typical characteristics !! Aspect: yellowish solid !! Melting point: 58 - 70°C !! Viscosity at 125°C: 50 – 500 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#
