Araldite 2080-05 & 2080-15 : Low-Odor Non-Flamable Toughened Weathering & Aging Resistant Flexible 5 & 15-minute Acrylic (MMA) Adhesive

Product Name

- Araldite 2080-05 & 2080-15: Low-Odor Non-Flammable Toughened Weathering & Aging Resistant Flexible 5 & 15-minute Acrylic (MMA) Adhesive

Brief Description

- Araldite 2080-05 and 2080-15 are two-part acrylic (MMA) structural adhesives designed to provide high strength and flexibility with very low odor.- These adhesives are non-flammable and offer excellent resistance to weathering and aging.- They are available with either a 5-minute (2080-05) or 15-minute (2080-15) open time for rapid assembly operations.

Popular Applications & Uses

- Bonding metal and composite studs and structures.- Bonding inside wind turbine blade add-ons.- Bonding panels, floors, and roof parts in buses.- Bonding automotive panels and trim.- Outdoor channel letter bonding and general outdoor sign industry applications.- General assembly operations on a wide range of substrates.

Industries that Commonly Use It

- Transportation/ Specialty Vehicle (e.g., buses, automotive)- Energy (e.g., wind turbines, oil and gas sectors)- Marine (e.g., bonding in vessels, demanding applications at sea)- General Manufacturing- Metal Fabrication- Plastic Fabrication- Sign & Display (e.g., outdoor signage)- Automotive Service/Repair- Petroleum Industry, Products or Services (e.g., oil and gas facilities)

Special and Unique Features

- **Low Odor:** Up to 90% less odor compared to traditional MMA products, improving worker comfort and satisfaction, especially in enclosed environments.- **Non-Flammable Classification:** Reduces costs associated with equipment, storage, transportation, safety instruction, and eliminates the need for flammable storage areas.- **Primer-Free Bonding:** Does not require a primer for most surfaces, unlike many PU and epoxy products, cutting costs and application time.- **Low Toxicity Profile:** Improved GHS classification, potentially reducing costs for personal protective equipment and risk management.- **High Strength and Flexibility:** Forms high-strength, high-elongation bonds with outstanding stress and impact resistance.- **Fast Curing:** Offers rapid reactivity times, similar to traditional MMAs, with 5-minute and 15-minute open time options.- **Weathering & Aging Resistant:** Provides excellent resistance to aging and weathering.

Key Properties

- **Technology:** Two-component Acrylic (MMA)- **Pot Life at RT:** 5 minutes (2080-05) / 15 minutes (2080-15)- **Fixture Time at RT:** 15-30 minutes- **Maximum Continuous Operating Temperature:** 90°C- **Tensile Strength:** >21 MPa (for 2080-05) / >25 MPa (for 2080-15)- **Tensile Modulus:** >1200 MPa- **Elongation at Break:** >50%- **Lap Shear Strength (Aluminum):** >2,900 psi (for 2080-05)- **Color (Mixed):** Off-White to Light Gray/Beige- **Shelf Life:** 24 months when stored at 2°C to 8°C (36°F to 46°F)

Surface Compatibility

- Most metals (primer-free bonding).- Composites.- Some plastics, including UP-GRP, SMC, ABS, PMMA, and PVC.- Ideal joint surfaces should be cleaned with a degreasing agent (e.g., acetone, iso-propanol for plastics) to remove oil, grease, and dirt.- Strongest and most durable joints are obtained by mechanically abrading or chemically etching degreased surfaces, though effective bonding can occur with little surface preparation.

Known backups / known substitutes

- **Traditional MMA Adhesives:** While Araldite 2080 improves upon them, conventional MMA adhesives are a type of structural adhesive.- **Polyurethane (PU) Adhesives:** Another category of structural adhesives that Araldite 2080 aims to outperform due to toxicity and primer requirements.- **Epoxy Adhesives:** Araldite 2080 offers primer-free bonding, a benefit over some epoxy products.- **Other Araldite Structural Adhesives:** - Araldite 2053-05/15 A/B: Two-part toughened methacrylate adhesive with high elongation and resistance to aging/weathering. - Araldite 2054-40 A/B: Two-part toughened methacrylate adhesive with long open time, high elongation, and excellent resistance to aging/weathering.

Comparison Note

- Araldite 2080-05 & 2080-15 directly address the common disadvantages of traditional Methyl Methacrylate (MMA) and Polyurethane (PU) adhesives.- It offers significantly lower odor (up to 90% less) compared to conventional MMAs, enhancing worker well-being in enclosed spaces.- Unlike many MMAs, it is non-flammable, leading to reduced safety, storage, and transportation costs.- It eliminates the need for a primer, a requirement often seen with PU and epoxy products, thereby reducing application time and costs while maintaining strong bonds.- The product also boasts a low toxicity profile, an improvement over certain PU adhesives.
