Araldite®2080 and Araldite®2081: Two Low-Odor MMA Adhesives for High-Performance Bonding
In the bonding industry, methyl methacrylate (MMA) adhesives are widely valued for their strength and rapid curing. However, their strong odor and flammability classification can pose challenges for professionals, particularly regarding workplace comfort, safety compliance, and the need for ventilation and personal protective equipment. Huntsman has developed an innovative response to these challenges with Araldite® 2080 and Araldite® 2081-10 GB, two low-odor MMA adhesives that combine high performance with improved working conditions.
Let’s take a closer look at what these adhesives have to offer.
Understanding Low Odor MMA Adhesives
MMA (methyl methacrylate) adhesives are highly resistant structural glues. They offer:
- Strong adhesion to various materials
- Fast curing for increased productivity
- High mechanical resistance to stress
- Low odor and non-flammable properties with Araldite® 2080 & Araldite® 2081
Araldite® 2080: Increased Resistance with Fewer Constraints
Araldite® 2080 is a two-component methacrylate adhesive designed to provide high resistance while significantly reducing the drawbacks of traditional MMA adhesives.

Main Applications
- Wind industry: Assembly of internal blade components
- Transportation: Bonding of panels and structures in buses and trains
- Marine: Ideal for confined space assemblies
- Signage: Fixing letters and signage panels
While Araldite® 2080 represents a major advancement, some applications require even more flexibility and resistance to dynamic stress. This is where Araldite® 2081 comes in.
Araldite® 2081: For Plastics and Demanding Environments
Araldite® 2081 is a complementary version of Araldite® 2080, offering high flexibility and improved compatibility with technical plastics.
Technical Characteristics
- Color: Off-white
- Density: 1.1 kg/m³

- Mixing ratio: 10:1
- Fixation time: 15-20 minutes
- Working time: 10 minutes
- Shear strength: 17 MPa
- Elongation at break: 70%
- Operating temperature: -40°C to 80°C
- Maximum gap: 2 mm
Why Choose Araldite® 2081?
✅ Adhesion to electronic equipment in addition to other applications
✅ Medical precision: Subject to biocompatible certifications
✅ Increased flexibility due to high elongation at break
✅ Expanded compatibility with various substrates, including technical plastics
✅ Fast curing, enabling quick handling of assembled parts
✅ Enhanced resistance to dynamic stresses, ideal for parts subjected to vibrations and shocks
✅ EN45545-2 certified
Specific Applications of Araldite® 2080 and 2081
- Wind industry: Fixing internal blade components, nacelle and junction box assembly, and emergency repairs.
- Transportation: Bonding exterior and interior panels in buses, trains, and trams, as well as fixing composite structures.
- Marine: Bonding structural elements of boats and yachts, reinforcing fiberglass hulls.
- Signage: Assembling road signs, bonding letters, and mounting signs onto metal or plastic structures.
- Railway industry: Fixing body elements, bonding vibration and impact-resistant interior and exterior panels.
Significant Emission Reduction: Improved Workshop Comfort
Comparative tests have confirmed a 90% reduction in odor compared to traditional MMA adhesives. These results are based on measurements of volatile organic compound (VOC) concentrations and user feedback from workshops.
Comparison: Araldite® 2080 vs. Araldite® 2081
| Characteristic | Araldite® 2080 | Araldite® 2081 |
|---|---|---|
| Reduced odor | ✅ 90% | ✅ 90% |
| Non-flammable | ✅ Flash point >95°C | ✅ Flash point >95°C |
| Flexibility | 85% elongation | 70% elongation |
| Shear strength | 25 MPa | 17 MPa |
| Temperature range | -40°C to 110°C | -40°C to 80°C |
| Preferred substrates | Metals (aluminum, stainless steel), composites (fiberglass, carbon) | Technical plastics (ABS, PC) |
A Solution for Every Need
These two structural adhesives meet different requirements:
- Araldite® 2080: Ideal for high-temperature environments (up to 110°C) and metallic substrates.
- Araldite® 2081: Designed for dynamic applications on technical plastics.
No single adhesive can meet all industrial requirements. That is why Huntsman has developed these two complementary solutions to cover most industrial applications with precision and performance.
Conclusion: A Dual Solution for Optimal Performance
Araldite® 2080 and 2081 adhesives offer an innovative and high-performance alternative to traditional MMA adhesives. Their low odor, enhanced safety, and versatility make them essential solutions for various industrial sectors.
