3M Scotch-Weld DP110 Flexible Temp Resistant 20-Minute Set Plastic & Metal Epoxy

Product Name

3M Scotch-Weld DP110 Flexible Temp Resistant 20-Minute Set Plastic & Metal Epoxy

Brief Description

3M Scotch-Weld DP110 is a translucent, flexible, fast-setting, two-part epoxy adhesive engineered to create strong, permanent bonds. It delivers excellent shear and peel strength, good impact performance, and maintains flexibility when cured, making it particularly effective for bonding dissimilar surfaces. This structural adhesive features a 1:1 mix ratio, a 10-minute work life, and achieves handling strength in approximately 20 minutes at room temperature.

Popular Applications & Uses

This versatile epoxy is ideal for general attachment, bonding, joining, gluing, assembling, and sealing applications. It can serve as an effective alternative to riveting or welding. Specific uses include filleting, potting, and structural bonding across various industries. It is also recommended for replacing 5-minute epoxies to achieve improved performance and allow for more positioning time.

• Aerospace/Defense
• Artist, Artisan
• Automotive Service/Repair
• Construction/ Building Services
• Electrical Services or Products
• General Manufacturing
• LED/Electronics
• Marine
• Metal Fabrication
• Plastic Fabrication
• Prosumer
• Sign & Display
• Transportation/ Specialty Vehicle

Special and Unique Features

• Flexible Bonds: Maintains strength under vibration and impact, making it ideal for bonding dissimilar surfaces and applications requiring flexibility.
• Fast Cure: Achieves handling strength in approximately 20 minutes at room temperature, with a 10-minute work life for positioning.
• Temperature Resistance: Offers excellent temperature resistance, performing well from -67°F to +300°F.
• Low Viscosity/Controlled Flow: Easy to dispense and self-level, making it effective for filleting and potting.

Known backups / known substitutes

• Maven EAF110 Flexible Epoxy Adhesive (also referred to as Maven EAF110 GEL)
• FlexEpox Flexible Epoxy Adhesive
• Infinity EP 100 FLEX
• General flexible vapor barrier or polyurea products (for flexible bonding, though clarity may vary)
• Other 3M Scotch-Weld epoxies, such as DP100 Plus (though DP110 is often used to replace 5-minute epoxies for improved performance).

Comparison Note

3M Scotch-Weld DP110 is a structural adhesive that offers superior performance compared to many common adhesives, including 5-minute epoxies, providing better heat and chemical resistance. Its key advantage lies in its cured flexibility, which allows it to maintain strong, permanent bonds even under vibration and impact, making it particularly suitable for bonding dissimilar surfaces where rigidity might lead to failure. While many epoxies cure rigidly, DP110 is specifically formulated to be flexible.
