La two-component adhesive is an industrial adhesive made up of two separate components: a resin and a hardener. During mixing, a chemical reaction occurs, generating a bond. extremely resistantadapted to structural bondingeven on difficult materials.
It is used in a variety of sectors, including the automotive, electronics, aerospace and construction industriesor industrial maintenance. The two-component adhesive offers excellent mechanical, chemical and thermal resistancewhere conventional adhesives reach their limits.
There are many benefits to using this glue:
The two-component epoxy adhesives are the most common for rigid structural assemblies :
Very high mechanical strength
Excellent heat resistance (up to +180°C)
Very good adhesion to metals, composites, wood and ceramics
Low polymerisation shrinkage → dimensional stability
Use in theaeronautics, railways, electronics, electric mobility
Ideal for structural metal-to-metal bondingor metal/compositewhere rigidity and precision are key.
The two-component methacrylate adhesives are formulated for assemblies where the speed and resistance on difficult substrates are essential:
Very good performance without primer on PE, PP, ABS, composites, PVC
Fast curing (a few minutes at room temperature)
High resistance to shock, vibration and fatigue
Tolerant of average surface conditions (slightly oily or damp)
Ideal for alternative mobility, plastics, construction, renewable energies
Recommended for bonding of composite hulls, casings, engineering plastics, covers, non-visible fasteners.
The two-component PU adhesives offer a a more flexible, moisture-resistant bondparticularly suitable for substrates exposed to deformations, thermal cycles or vibrations :
Excellent flexibility (Shore A to D depending on formulation)
Resistant to moisture, water, oils and fuels
Good adhesion to porous or uneven substrates (concrete, wood, composites)
Used in theautomotive, construction, on-board electronics
Particularly useful for assemblies subjected to dynamic stress or outdoor bonding.

It's an adhesive made up of two parts to be mixed (resin and hardener). Once mixed, they react chemically to form a very strong structural bond, even on materials that are difficult to bond.
La two-component needs to be mixed in advance, but offers superior strength. La single component is ready-to-use, simpler to apply, but less effective for demanding assemblies.
You can stick metals, engineering plastics, composites, wood, concrete, glass, ceramicsand even combined surfaces. It's an ideal solution for multi-material bonding.
Yes. There are formulations to rapid setting (a few minutes) or slow grip (more than 60 minutes). The choice depends on the type of assembly, the desired working time and production constraints.
Yes. Depending on the wording, it can withstand temperatures of up to +250°C and many chemicals (oils, fuels, solvents, light acids, etc.).
Absolutely. Many solutions are compatible with automatic dosing/mixing systemsperfect for production lines or mass bonding.
