Epoxy

High-Strength 2-Part Adhesives

Structural Epoxy Adhesives

Two-Component (2K) epoxies for metal, composite, stone, and engineered plastic bonding.

Engineered for extreme durability and load-bearing applications, these industrial-grade 2-part epoxy systems replace welding, screws, and rivets. Choose from fast-setting, toughened, or gap-filling formulas—all with precise dual-cartridge dispensing.

2K Structural Adhesives: Your Guide to High-Performance Bonding

Choosing between Epoxy, MMA, and Urethane means balancing speed, flexibility, and environmental resistance for your project. All three provide high-strength, durable bonds that often replace welding and fasteners.

Epoxy — Strength & Resilience

  • Highest overall bond strength and heat resistance
  • Rigid, long-term bonds on metals, stone, and composites
  • Best for: concrete, metals (prepped), wood, composites

MMA — Speed & Versatility

  • Fast cure and minimal surface prep
  • Ideal for bonding dissimilar substrates
  • Best for: plastics, composites, metal fabrication

Urethane — Flexible & Impact

  • High elongation and shock absorption
  • Excellent UV and weather resistance
  • Best for: painted metals, plastics, rubbers, foams

Why Choose Structural Epoxy

  • High shear and peel strength for permanent, load-bearing joints.
  • Excellent chemical and heat resistance for long-term reliability in harsh environments.
  • Gap-filling and non-sag options ideal for vertical, overhead, or uneven surfaces.
  • Dual-cartridge packaging for clean, consistent 1:1 or 2:1 mix ratios without manual measuring.

Featured Brands & Flagship Products

Parker Lord®
