3M™ Scotch-Weld™ DP490 Structural adhesive (MR 2:1) double cartridge, 50 ml

3M™ Scotch-Weld™ DP490 – High-Performance Adhesive for Extreme Loads

The 3M™ Scotch-Weld™ DP490 is a high-performance, thixotropic two-component structural adhesive that cures at room temperature and provides outstanding strength for structural bonding applications. It has been specifically developed for applications exposed to mechanical, thermal, and dynamic loads, such as in the rail industry, aerospace, and automotive sectors.

Thanks to its high temperature resistance of up to 120 °C and its excellent environmental resistance, DP490 remains reliable and stable even under extreme conditions. The adhesive’s unique toughened properties ensure excellent impact resistance as well as outstanding resistance to static and dynamic stresses.

Features & Benefits

• Extremely high strength – Designed for highly stressed bonded joints
• Excellent impact and peel strength – Withstands dynamic loads
• Outstanding temperature resistance – Withstands temperatures up to 120 °C
• Thixotropic & non-sag – Ideal for vertical surfaces and hard-to-reach areas
• Easy processing & high stability – Long working time of 90 minutes
• Good adhesion to powder-coated surfaces & plastics – Versatile in use
• Reliable weathering and aging resistance – Durable bonded joints

Applications

• Bonding of metals & composite materials – High-strength joints without mechanical fasteners
• Transportation industry (rail & automotive) – Resistant to vibration and dynamic loads
• Bonding of powder-coated and coated surfaces – Reliable adhesion to difficult substrates
• Manufacturing & industrial applications – High bond strength for demanding constructions
• Marine and yacht construction – Structural bonding of GFRP/CFRP components, e.g. deck-to-hull joints, installation of stringers, bulkheads, or reinforcement structures; suitable for highly loaded areas exposed to varying mechanical and environmental conditions (moisture, temperature, vibration)
