Known backups / known substitutes

- Other fast-setting, two-component urethane adhesives from various manufacturers.- Hardman Urethane 04024 (General Purpose Purple & Beige Package), which is also a fast-setting, tough, and flexible urethane adhesive with high peel strength.- Fast-curing automotive glass urethanes (e.g., 3M™ Fast Cure Auto Glass Urethane, Pro Form Fast Cure Urethane Windshield Adhesive) for applications requiring rapid strength build-up and impact resistance on glass and other substrates, though these are often one-part moisture-curing.- Bostik 915FS, a one-component, fast-setting polyurethane sealant/adhesive designed for dynamic joint movement.

Comparison Note

- Hardman Double Bubble D85, as a polyurethane adhesive, offers superior flexibility and impact resistance compared to many epoxy adhesives, making it ideal for applications subject to movement, vibration, or shock.- Polyurethane adhesives generally provide better UV and weather resistance than some epoxies, enhancing their suitability for outdoor exposure.- While epoxies are often noted for higher rigid bond strength and chemical resistance, D85's fast 5-minute work time provides a significant advantage for quick repairs and assembly where rapid handling strength is crucial, often curing faster than many traditional epoxies.
