Buying Guide

Match epoxy type to the job

Choose two-part liquid epoxies for structural bonds and self-metering cartridges for consistent mixes; putty or paste forms work better for gap-filling and shaping

Check compatibility with substrates

Confirm the product lists metal, wood, or fiberglass compatibility—marine-grade formulations are typically formulated for metals and composites exposed to moisture

Consider working time and cure speed

Longer open time lets you reposition parts; faster cures reduce clamp time but can be harder to work with in complex assemblies

Evaluate mechanical properties

Look for data on tensile strength, shear strength, and impact resistance when you need load-bearing or vibration-resistant joints

Assess packaging and mixing method

Self-metering cartridges and pre-measured two-part kits reduce mixing errors; bulk paste or putty is more economical for large fills
