Material Notes:

Master Bond Polymer System EP30M4 is a two component epoxy system for high performance bonding, sealing and encapsulation. This system features a forgiving 100 to 60 mix ratio by weight. EP30M4 resists water, acids, bases, fuels and oils, along with many aggressive solvents. Some of the potent chemicals it can resist include skydrol, xylene, 70% sulfuric acid, 98% sulfuric acid, 50% sodium hydroxide and bleach.
