Mechanical abrading or chemical etching can further enhance bond strength and durability.
Known backups / known substitutes
Please note that Araldite 2022-1 in 50ml cartridges has been discontinued by Huntsman Advanced Materials, though other pack sizes (e.g., 380ml) or component forms (resin F 362-1 and hardener F 362-1) may still be available.- **Plexus MMA Adhesives:** Such as Plexus MA300, MA310, MA320, MA550, MA560-1, MA8210, MA205HV, which are also two-part methacrylate adhesives known for structural bonding of thermoplastics, metals, and composites with minimal surface preparation.- **Infinity Bond MMA Adhesives:** For example, Infinity Bond MMA 310, formulated for difficult substrates like metals, plastics, and fiberglass, offering strong bonds with little to no surface preparation.- **Other MMA Adhesives:** From brands like ASI, LOCTITE (Acrylics), and SCIGRIP.- **Epoxy Adhesives:** While generally having longer cure times and sometimes requiring more surface preparation, epoxies like JB Weld can be considered for high shear and tensile strength applications, especially where less flexibility is acceptable.
Comparison Note
Huntsman Araldite 2022-1 stands out as a toughened MMA adhesive offering a balance of fast cure, high impact resistance, and broad material compatibility, particularly excelling in bonding thermoplastics and dissimilar substrates with minimal surface preparation. Compared to traditional epoxies, MMA adhesives like Araldite 2022-1 generally offer faster cure times, better flexibility, and superior impact and peel strength, making them ideal for dynamic applications and production environments where speed and resilience are critical.
