Buying Guide

Match epoxy type to the job

Choose putty fillers for gap filling and sculpting, liquid resins for coating and bonding, and metal-filled formulas for electrical conductivity or machinability

Check working and cure times

Short-set epoxies speed small repairs but limit repositioning; longer working times help complex assemblies and larger laminations

Consider substrate compatibility

Pick marine-grade or flexible epoxies for boats and wet environments, and formulations labeled for wood, metal, or fiberglass for reliable adhesion

Evaluate strength and flexibility

Stiffer epoxies give higher compressive and shear strength while flexible systems resist impact and vibration on dissimilar materials

Factor kit size and mixing format

Buy pastes or large kits for structural repairs and small syringe or twin-pack options for quick fixes and precise dosing
