METLBOND® 1515-3
METLBOND® 1515-3 and METLBOND® 1515-3 HT are 350°F (177°C) curing modified epoxy supported film adhesives. These materials can also be cured at 250°F (121°C). Maximum continuous service temperature ranges from 275°F to 320°F (135°C to 160°C). METLBOND® 1515-3 HT was designed for improved layup of complex honeycomb structures by increasing the cohesive tack of the material. METLBOND® 1515-3 and METLBOND® 1515-3 HT have equivalent chemical, physical and mechanical properties. Additionally, METLBOND® 1515-4 has equivalent chemical, physical and mechanical properties with an extended out time of 30 days.
Typical applications for METLBOND® 1515-3 primarily include composite bonding, although it is also suitable for a variety of metal bonding applications.
