Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive 7240FR is a high-performance, two-part toughened epoxy designed for creating strong, rigid, and durable bonds. Its non-sag formula prevents dripping on vertical surfaces, while integrated glass beads ensure precise glue line control. With a 45-minute work life, this 2:1 mix ratio epoxy allows ample time for positioning parts before it cures to handling strength in approximately 6 hours. Offering high shear and peel strength, it excels in demanding industries like metalworking, transportation, and aerospace, providing excellent dead load holding and resistance to heat and chemicals.
3M™ 7240 Features
- High-Performance Formula: A two-part toughened epoxy that delivers exceptional shear and peel strength for outstanding durability.
- Non-Sag Consistency: Ensures the adhesive stays in place on vertical surfaces for clean, easy application.
- Extended Work Life: A 45-minute open time provides flexibility for adjusting and positioning large or complex parts.
- Flame Retardant: Formulated to meet specific fire safety standards in various industries.
- Glue Line Control: Contains glass beads to ensure a consistent and accurate bond line thickness.
3M™ 7240 Applications
- Rail bonding for materials such as stainless steel, aluminum, and fiberglass.
- General industrial tasks where high durability and flame resistance are required.
- Metalworking applications that require strong, rigid, and reliable bonds.
- High-strength assembly tasks within the transportation industry.
- Aerospace manufacturing where reliable, high-performance adhesion is critical.
