Adhesives FAQ
Epoxies offer high strength, chemical resistance, and excellent adhesion to metals and rigid substrates. Urethanes are more flexible, making them ideal for bonding materials with different thermal expansion rates or for applications needing impact resistance.
Epoxy adhesives generally perform better at elevated temperatures, often maintaining strength and stability above 120°C. Urethanes are better suited for low to moderate temperatures and applications requiring flexibility.
Yes, both can bond to plastics, but surface preparation is key. Urethanes are often preferred for flexible plastics, while epoxies work well on rigid plastics with proper primers or surface treatment.
Cure times vary. Epoxies can cure in minutes to hours depending on the formulation, while urethanes typically cure faster but may require moisture or heat. Both are available in fast-setting and extended-working-time versions.
