Two-component methacrylate adhesive: the high-performance adhesive

What is a two-component methacrylate adhesive?

Two-component methacrylate adhesive (or MMA adhesive) is an structural adhesive high-performance, designed for durable bonding of difficult materials plastics, composites, metals or technical alloys. Made up of two components - a base and a hardener - it is distinguished by its low viscosity. fast setting timea exceptional grip without a primary, and a high mechanical strength. 

In demanding industrial environments, methacrylate glue is the ideal choice. effective alternative to riveting or weldingThis saves time, weight and assembly flexibility.

Advantages of two-component methacrylate adhesives

  • Direct adhesion on difficult surfaces: aluminium, stainless steel, thermoplastics, composites, glass, etc. 
  • No need for a primaryeven on low-energy plastics (ABS, PVC, PC, etc.) 
  • Fast setting time 3 to 15 min depending on formulation 
  • High mechanical strength and vibration resistanceeven in harsh environments 
  • Good resistance to weathering, UV, solvents and thermal shock 
  • Low shrinkagecompatible with visible or aesthetic parts 

Two-component methacrylate adhesive is a solution for structural bonding ideal for replacing traditional mechanical fasteners. 

Automotive and transport 

  • Assembly of bonnets, spoilers, bumpers or reinforced plastic shells 
  • Bonding composite elements to metal structures (aluminium, steel) 
  • Fast fixing on the production line, with no post-cure rework 

Energy, rail and heavy industry 

  • Gluing control boxes, bodywork components, doors and hatches 
  • Sealing between composite or engineering plastic parts 
  • Assemblies subject to severe vibration or thermal stress

FAQ - Two-component methacrylate adhesive

Methacrylate adhesive offers faster settinga greater flexibility and bonds difficult materials without primer, where epoxys often require surface treatment.

Metals (aluminium, stainless steel), composites, thermoplastics, glass, wood... Methacrylate adhesive is one of the few two-component adhesives to offer a high level of performance. direct adhesion to all these substrates.

Lifetime after mixing varies from 2 to 20 minutes depending on the formulation. Ideal for fast production rates or assembly of medium-sized parts.

No. One of the major advantages of methacrylate is its ability to adhere directly, even to non-porous or low-energy substrates.

Yes, some methacrylate adhesives ". low odor " such as the 3M™ DP8405NS or Permabond 720/730 reduce odour without compromising performance.
