Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive DP490 is a thixotropic, two-part structural adhesive engineered for the most demanding high-strength applications. Its non-sag formula is perfect for applying to vertical surfaces without dripping or slumping, ensuring a clean and precise bond line. This adhesive delivers outstanding performance with excellent heat resistance up to 248°F (120°C), superior shear and peel strength, and good impact durability. It excels at bonding difficult surfaces, including powder-coated metals and most plastics. With a generous 90-minute work life, users have ample time to adjust and position components before the adhesive cures to a strong, long-lasting bond, making it an ideal choice for complex assemblies in the rail and automotive industries.
3M™ DP490 Features
- High Strength: Thixotropic properties deliver high peel and shear strength for robust bonds.
- Non-Sag Formula: Allows for clean and easy application on vertical surfaces.
- Long Work Life: A 90-minute work life provides ample time for repositioning parts.
- High-Temperature Resistance: Performs reliably in temperatures up to 248°F (120°C).
- Impact Durability: Creates a tough, durable bond that resists impact and vibration.
- Convenient Dispensing: Duo-Pak cartridge ensures accurate metering and mixing with 3M dispensing equipment.
3M™ DP490 Applications
- Transportation: Ideal for high-strength structural bonding in rail and automotive applications.
- Difficult Substrates: Effectively bonds powder-coated metals, composites, and a wide range of plastics.
- Heavy-Duty Assembly: Suitable for demanding applications where maximum strength and environmental resistance are required.
- Vertical Bonding: Use where a non-sag adhesive is needed for overhead or vertical surface assembly.
