Buying Guide

Match epoxy type to the job

Choose adhesive-grade epoxies for bonding parts and deep-pour resins for thick pours or casting to avoid heat and shrinkage issues

Check pot life and cure speed

Longer pot life helps with large pours or slow work, while faster cures let you demold sooner; pick based on project timeline

Consider viscosity and flow

Low-viscosity epoxies wet surfaces and penetrate joints; high-viscosity or thixotropic formulas are better for gap-filling and vertical surfaces

Look for clarity and UV resistance

Crystal-clear resins retain appearance in castings; UV-stable formulas prevent yellowing for visible surfaces

Assess dispensing and mixing convenience

Cartridge-and-gun systems reduce mixing error for repairs, while kit packs and gallon options suit larger projects and continuous pours
