Ultralok Structural Adhesives

A Better Approach for Manufacturing & Assembly

Ultralok® Structural Adhesives

Industrial-Strength MMA, Epoxy & Polyurethane

If you’re trying to replace welding, rivets, or messy mechanical fastening, Ultralok® is built for that kind of work.

Formulated for high-volume manufacturing, the Ultralok series delivers high shear strength, impact resistance, and rapid fixture times to optimize production cycles on metals, plastics, and composites.

Cross-Substrate Bonding

High Shear & Impact

Adjustable Cure Times

Replaces Welding/Rivets

The Ultralok® Structural Adhesive Series

10:1 MMA (4XX Series)

Rapid fixture times for high-speed assembly. Designed for bonding metals, plastics, and composites where speed matters.

1:1 MMA (3XX Series)

Extended open times for staging, aligning, and clamping. Delivers strong, durable bonding on a wider mix of materials.

Structural Epoxies

Maximum chemical resistance and rigidity. Ideal for assemblies that need a tougher bond line and stable performance over time.

Polyurethanes

Flexible strength for high impact and vibration. A great option for plastics, foams, and applications that need a little “give”.

Stick with the SmartPAK™

SmartPAK System

Many of our Ultralok adhesives are available in our eco-friendly SmartPAK packaging. It uses less than 1% plastic, reduces environmental waste, and provides 38% more product at a highly cost-effective rate.

Available in 600ML and 1200ML high-efficiency formats.
