Material Notes:

Master Bond Polymer System EP51FL-1 is a two component highly flexible epoxy resin system for high performance bonding sealing and coating. Although most flexiblilized epoxy formulations are very slow curing, EP51FL-1 offers a relatively rapid cure, with a setup time in most cases of about 30-40 minutes and full cure within 24 hours at room temperature. EP51FL-1 has been used in cryogenic applications as both an adhesive and sealant. Its service temperature range is 4K to 250°F.
