Description
Araldite 2021-1 is a two-component, toughened methacrylate adhesive (MMA) engineered for rapid assembly operations. It excels at bonding dissimilar materials, such as metal to plastic, with minimal surface preparation. With a work life of just 3-5 minutes and handling strength in 8 minutes, it provides the speed of a super glue with the structural strength and impact resistance of a toughened epoxy.
Compatible Popular and Unique Surfaces
- Metals: Aluminum, Steel, Stainless Steel (often no primer needed).
- Thermoplastics: ABS, PVC, Polycarbonate, Polyamide, Acrylics.
- Composites: FRP, CFRP, Epoxy Laminates.
- Others: Glass, Quartz, Ceramic.
Unique and Call-Out Features
- Bond Dissimilar Materials: Unique chemistry allows high-strength bonds between metals, composites, and thermoplastics.
- Minimal Prep: Often cuts through surface oxidation and contamination, requiring less sanding/priming than epoxies.
- Rapid Throughput: Extremely fast fixture time (8 mins) enables high-speed manufacturing and quick part cycling.
- Toughened: Formulated to resist high peel loads, shock, and vibration.
