Product Name
- Araldite 2023-10, 30, & 60 Flexible Toughened Foaming Gap-Filling MMA - 10, 30, 60-Minute Set
Brief Description
- Araldite 2023 is a series of two-component, room-temperature curing, flexible, and toughened methyl methacrylate (MMA) adhesives.- These structural adhesives are designed for tough joining and sealing of large and complex parts, offering excellent gap-filling capabilities and varying open times of 10, 30, or 60 minutes.- They are thixotropic pastes that can fill gaps up to 30 mm.
Popular Applications & Uses
- Bonding composites and metals in various structural applications.- Manufacturing of large composite structures.- Bonding parts and components in the automotive and aerospace industries, often replacing welding or mechanical fastening.- Marine applications for bonding fiberglass, plastics, and other materials in boats and vessels.- Structural bonding in transportation (e.g., bus manufacturing for panels) and infrastructure.- Joining aluminum, steel, powder-coated parts, ABS, acrylic, PVC, or polycarbonate in fabrication.- Bonding acrylic panels, frames, and metal supports in signage and displays.- General industrial assembly and production lines due to rapid cure speed.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Fabrication- General Manufacturing- Marine- Metal Fabrication- Plastic Fabrication- Sign & Display- Transportation/ Specialty Vehicle- Energy (e.g., wind power, for large composite structures)
Special and Unique Features
- **Flexible and Toughened Bonds:** Engineered for dynamic environments and to cope with differential thermal expansion and contraction.- **Foaming Gap-Filling Capability:** Can fill large gaps up to 30 mm, making it ideal for irregular surfaces or high tolerance fits.- **Varying Open Times:** Available in 10, 30, and 60-minute set times to suit different application needs and production speeds.- **Room Temperature Curing:** Cures quickly at room temperature, developing full bond strength soon after application without external heat.- **UV Stable:** Maintains its bright grey color and does not yellow with time or exposure to sunlight.- **Minimal Surface Preparation:** Tolerant to less-than-ideal pretreatment conditions and can be used effectively with little surface preparation.- **Non-Sagging:** Thixotropic paste formulation prevents sagging, making it suitable for vertical and complex bonding applications.
Key Properties
- **Chemical Family:** Methyl Methacrylate (MMA)- **Components:** Two-component (2K) adhesive- **Cure Type:** Room temperature curing- **Open Time:** 10, 30, or 60 minutes- **Gap Filling:** Up to 30 mm- **Elongation at Break:** Greater than 100%- **Color:** Bright grey, UV stable- **Consistency:** Thixotropic paste- **Bond Strength:** High shear, peel, and impact resistance.- **Environmental Resistance:** Good resistance to temperature swings, vibration, and chemical exposure.
Surface Compatibility
- Composites- Metals (e.g., aluminum, steel, powder-coated parts)- Plastics (e.g., acrylics, cast acrylics, polyesters, thermoplastics, ABS, PVC, polycarbonate)- Fiberglass- Concrete- Wood- Glass- Magnets
Known backups / known substitutes
- Other Methyl Methacrylate (MMA) adhesives from various manufacturers.- Two-part epoxies (though MMAs offer faster cure, better peel strength, and less surface prep).- Polyurethane adhesives (MMAs offer higher bond strength on a broader range of materials, faster cure, and are less sensitive to moisture).- Welding or mechanical fastening (MMAs can replace these in many applications due to high strength and durability).- Expanding polyurethane foam sealants for general gap filling, though Araldite 2023 is a structural adhesive.
Comparison Note
- Araldite 2023 series stands out among structural adhesives due to its unique combination of flexibility, toughening, foaming gap-filling capabilities, and UV stability, particularly for large and complex assemblies.- Unlike many epoxies, it cures quickly at room temperature and requires minimal surface preparation, enhancing productivity.- Its high elongation at break and resistance to dynamic environments make it superior for applications where parts experience movement or stress.
