Material Notes:

Master Bond Polymer System EP42HT-2LO is a room temperature curable two component epoxy, adhesive, sealant, coating and casting material featuring high temperature resistance along with outstanding chemical resistance. EP42HT-2LO is a superior epoxy adhesive system and is castable to thicknesses exceeding 2-3 inches. EP42HT-2LO cures readily at ambient temperatures or more quickly at elevated temperatures. One particularly popular cure schedule is overnight at room temperature followed by 2-4 hours at 150-200°F. EP42HT-2LO has excellent physical strength properties and dimensional stability. It is suitable for cryogenic service down to 4K.
