3M ScotchWeld DP405 Black 5-Minute Toughened Epoxy Adhesive

Description

3M Scotch-Weld DP405 is a two-part, rapid-setting toughened epoxy adhesive that provides strong, durable bonds with excellent impact and vibration resistance. Its 5-minute work life makes it ideal for fast-paced production environments, while its toughened nature allows it to absorb impacts and stresses that would cause more brittle epoxies to fail. It is a versatile choice for bonding a wide variety of materials, including metals and many plastics

Popular Applications & Uses
– Bonding components in sporting goods that experience high impact, such as golf clubs and skis.
– Assembly of small joints, brackets, and mounts in industrial applications.
– Fast-paced product assembly where quick handling strength is required.
– Bonding carbon fiber composites, metals, and plastics with high peel strength requirements.

– Devcon 5-Minute Epoxy

Comparison Note
– The key feature of 3M DP405 is its combination of speed and toughness. Compared to a standard 5-minute epoxy like Devcon’s, DP405 offers significantly better impact and peel strength. Compared to a higher-performance epoxy like 3M DP420, DP405 provides a much faster cure at the expense of some ultimate strength and a shorter positioning time.
