Product Name
Maven EAF490 - Slow Set 90 minute Epoxy - Toughened 90-minute Set Epoxy Adhesive
Brief Description
Maven EAF490 is a two-component, room temperature curing, multipurpose toughened epoxy adhesive. It offers excellent strength and toughness with a 90-minute set/cure time. This adhesive is specifically formulated to provide enhanced toughness and impact resistance, making it suitable for applications that require resilience against vibration, impact, or dynamic loads.
Popular Applications & Uses
- Bonding components in structural assemblies.- Crash-zone repair in automotive applications.- Bonding of wind turbine blades.- Structural strengthening of steel members, particularly for fatigue-damaged structures.- Bonding, sealing, or encapsulating various electrical, optical, and medical components.- Creating durable molds and tooling fixtures.- General industrial, craftsmen, and DIY bonding tasks.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Construction/Building Services- Electrical Services or Products / LED/Electronics- Engineering Services- Fabrication / Metal Fabrication / Plastic Fabrication- General Manufacturing- Marine- Medical Device/Prosthetics- Mold Making/Casting- Transportation/Specialty Vehicle
Special and Unique Features
- Toughened formulation for enhanced impact resistance and overall durability.- Increased toughness allows the adhesive to withstand impacts and mechanical stress without cracking or failing.- Improved flexibility and ductility, enabling it to absorb energy and distribute stress more effectively.- Slow 90-minute working time, providing ample time for complex assemblies or large application areas.- Exhibits excellent shear and peel strength, ensuring reliable bonding performance.- Electrically insulating properties.- Offers excellent environmental performance and resistance.
Key Properties
- Set/Cure Time: 90 minutes (working time), full cure typically within 24 hours.- Color: Dries Off-White.- Viscosity: Medium (15,000 to 30,000 cps).- Two-component system, cures at room temperature.- High strength and durability.- Excellent impact and vibration resistance.- Good temperature resistance, maintaining mechanical properties over a wide range.- Resistant to chemicals and moisture.- Cures with low residual stresses, beneficial for dissimilar substrates.
Surface Compatibility
- Excellent bonder for Steel (ferrous and stainless).- Excellent bonder for Aluminum.- Good bonder for many types of Plastics.- Generally compatible with a wide range of materials including metals, plastics, composites, ceramics, glass, wood, concrete, stone, marble, porcelain, and bamboo.- For optimal adhesion, smooth, non-porous surfaces should be roughened with coarse sandpaper.- Not recommended for use with very low surface energy plastics such as Polyethylene (PE), Polypropylene (PP), PTFE (Teflon), and Silicone, unless industrial-grade chemical primers or surface treatments are applied.

Comparison Note
Toughened epoxies like Maven EAF490 offer significant advantages over standard, more rigid epoxies by providing enhanced toughness and impact resistance. Standard epoxies can be brittle and prone to cracking under impact, vibration, or temperature fluctuations, whereas toughened formulations are designed to absorb energy and distribute stress more effectively. The 90-minute slow set time of EAF490 provides a considerably longer working window compared to fast-set epoxies (e.g., 5-minute epoxies), which is crucial for intricate assemblies, large-scale applications, or when precise positioning is required. While offering superior flexibility and impact resistance, it maintains the high strength, durability, and resistance to chemicals, moisture, and temperature that are characteristic of high-performance epoxy adhesives. Compared to some alternatives like polyester resin, epoxy generally provides superior bond strength, lower shrinkage, and less volatile organic compound (VOC) emissions, though it may be a higher cost option.
