Features Of Araldite 2021 Toughened Acrylic Adhesive

  1. High impact and peel resistance due to elastomer-toughened acrylic formulation.

  2. Excellent adhesion to low-surface-energy substrates including polypropylene, polyethylene, and untreated plastics.

  3. Fast fixture strength — achieves handling strength in under 15 minutes at room temperature.

  4. Good resistance to thermal cycling, humidity, and common industrial chemicals.

  5. Two-component system with simple 10:1 mix ratio by volume for consistent performance and ease of use.

Typical Applications Of Araldite 2021 Toughened Acrylic Adhesive

  1. Automotive exterior trim bonding (e.g., grilles, badges, light assemblies).

  2. Electronics assembly requiring vibration-damping structural adhesion (e.g., sensor housings, battery enclosures).

  3. Industrial equipment manufacturing where metal-to-plastic or dissimilar substrate bonding is required.

  4. Transportation sector applications including rail interior components and bus body panel attachment.

  5. Consumer appliance assembly involving durable, non-welded structural joints.
