Two-component acrylic adhesive: adhesion and structural strength

What is a two-component acrylic adhesive?

La two-component acrylic adhesive is a high-performance structural adhesive based on a chemical reaction between two distinct components: a acrylic resin and a activator or hardener. This bonding system makes it possible to obtain a extremely strong connectioneven on materials that are difficult to bond. 

Designed for demanding industrial applications, this adhesive offers an excellent fast setting timea excellent mechanical strengthas well as a multi-substrate adhesion without the need for a primer. It is ideal for replacing mechanical fasteners (screws, rivets, welds) as part of a strategy of productivity gains and weight reduction assemblies. 

Advantages of two-component acrylic adhesive

Used in many technical sectors, this adhesive offers a unique combination of performances: 

  • High adhesion without primer on metals, plastics, composites, glass, etc. 
  • Fast setting time Handling possible in just a few minutes. 
  • Structural strength (traction, shearing, peeling). 
  • Assembly clearance tolerance up to several millimetres depending on the version. 
  • Excellent chemical resistance oils, fuels, solvents. 
  • Temperature resistance up to +120°C to +180°C depending on the part number. 
  • Good filling properties and clearance compensation. 
  • Aesthetically pleasing bondingwithout deforming the parts. 

Industrial and mechanical assembly 

It is used for replace traditional fasteners in industrial environments, where structural strength, productivity and aesthetics are essential. 

  • Bonding metal or composite structures 
  • Fixing of casings, chassis, covers, technical components 
  • Replacement of welds or rivets to avoid thermal stresses 

Automotive, transport and mobility 

Particularly suitable for multi-material assembliesIt is used in the manufacture of : 

  • Bonnets, tailgates, exterior panels (metal/composite bonding) 
  • Interior trim and design features 
  • Bonded reinforcements on bodywork, lightweight structural parts 

Energy, construction and industrial joinery 

It enables fast, solid and durable assemblies in the following sectors modular buildings, ventilated facades and renewable energies. 

  • Fixing frames, supports and equipment 
  • Bonding sandwich panels or heterogeneous materials 
  • Assemblies subject to vibration and extreme climatic conditions

FAQ - Two-component acrylic adhesive

It is an industrial adhesive composed of two elements (resin + hardener) which, when mixed, react chemically to form a highly resistant structural bondingsuitable for metals, plastics or composites, without primer. 

La epoxy glue is stiffer and slower to harden, but resistant to very high temperatures. The two-component acrylic adhesive is faster, more flexibleIt requires no primer and is often more tolerant of poorly prepared surfaces. 

Depending on the wording, the The initial dose can be taken in 2 to 15 minutesand the final resistance is reached in a few hours at room temperature. Ultra-fast-curing versions are available for automated production lines. 

It effectively bonds the metal, aluminium, stainless steel, plastic (ABS, PC, PMMA), composite, wood, stone, etc.and even painted or slightly contaminated surfaces. 

Yes. Most of these glues are compatible with automatic dosing/mixing systemswhich makes it possible to increased productivity, precise application and perfect repeatability. 

Yes. It offers excellent resistance to moisture, solvents, vibration and mechanical impactwhich makes it ideal for demanding or mobile industrial environments (automotive, boating, etc.).
