Structural Acrylic (MMA)

High-Throughput 2-Part Acrylics

Structural Acrylic (MMA) Adhesives

Two-Component (2K) MMAs for plastics, composites, and metal fabrication.

Structural Acrylics based on Methyl Methacrylate (MMA) are the fastest, most forgiving structural adhesives—achieving handling strength in minutes with minimal surface prep. They form tough, durable bonds between dissimilar materials, making them indispensable in automotive, transit, marine, and composite manufacturing.

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

  • Very fast fixture; minimal surface prep
  • Excellent on dissimilar, non-porous 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 MMAs

  • Fastest cure & fixture — handling strength in minutes to accelerate production.
  • Bond almost anything — metals, thermoplastics (ABS, PVC, acrylics), and composites; great for dissimilar materials.
  • Minimal surface prep — designed to tolerate minor oils and contaminants.
  • Excellent toughness — flexible bond lines resist peel, impact, and fatigue.
  • Low-temperature, room-temp cure — no heat required.
