Huntsman Araldite 2021-1 Acrylic Adhesive, 50 mL

Description

Araldite 2021-1 is a two-component methacrylate structural adhesive for rapid assembly work across metals, plastics, composites, glass-reinforced plastic, polycarbonate, PVC, and sheet molding compound. Huntsman positions it as a room-temperature curing grade for production teams that need quick fixture speed, broad substrate coverage, and a tough bond without moving to a heat-cure process.

Araldite 2021-1 Benefits

• Toughened methacrylate chemistry helps the bond handle movement, peel stress, and mixed-material joints.
• Room-temperature cure supports shop use where ovens and heated fixtures are not practical.
• Broad substrate compatibility reduces the need to switch adhesives between composite, plastic, and metal assemblies.
• Cartridge packaging works with disposable static mixers for cleaner meter and mix application at the bench.
• Fast assembly response helps crews keep parts moving through trim, enclosure, panel, and general fabrication work.

This grade fits transportation, marine, industrial, and utility builds where operators need one adhesive that can bridge several common substrates in the same cell. The Huntsman product page lists use across seats, windscreens, shelves, roofs, boats, and other component assemblies, which makes it a practical option when a general-purpose structural acrylic is easier to stock than several niche grades.

Araldite 2021-1 Applications

• Bonding composite panels, covers, and structural trim parts.
• Joining metals to plastics in housings, brackets, and equipment enclosures.
• Assembling PVC, polycarbonate, and GRP components.
• Repair and build work on marine parts, utility assemblies, and transport interiors.
• Production cells that use 50 mL cartridges with disposable 18 to 21 element mixing nozzles.

Clean and degrease the joint faces before bonding. Huntsman notes that the strongest and most durable joints come from proper surface treatment, with mechanical abrasion or chemical etching used where the application calls for added bond reliability. Abrading should be followed by a second degreasing step so oil, dust, and shop residue do not stay trapped in the bond line.
