Permabond 240 Cyanoacrylate Adhesive

Permabond 240 is a high-viscosity cyanoacrylate adhesive designed for fast, strong bonds across a variety of materials. Its high viscosity makes it particularly effective in large gap applications and on porous substrates, ensuring a reliable bond even in challenging conditions. This 100% reactive, solvent-free adhesive cures rapidly upon contact with surface moisture, making it ideal for high-speed production environments where efficiency is paramount.

Key Features of Permabond 240

• Rapid development of high strength
• Ease of use – no mixing or heat cure required
• Bonds most materials, including plastics, rubber, and metals
• High viscosity for large gap filling
• Ideal for porous substrates
• 100% reactive, no solvents

Technical Overview

• Chemical Properties: Ethyl cyanoacrylate
• Application Temperature Range: Room temperature (optimal)

Trade Professional Information

• Required Tools: Dispensing nozzles, surface preparation solvents (acetone, isopropanol), emery cloth for metal abrasion.
• Trade-Specific Tips: Ensure surfaces are clean and dry before application. For difficult-to-bond materials like polypropylene or polyethylene, use Permabond Polyolefin Primer (POP). For faster curing on acidic surfaces, use Permabond C Surface Activator (CSA) or Permabond QFS 16.
• Common Issues and Solutions: Blooming (white residue) can occur in high humidity; ensure proper ventilation. Inconsistent bond strength can result from contaminated surfaces; thorough cleaning is essential.

Storage and Shelf Life

• Storage Requirements: 2°C to 7°C (35°F to 45°F) in a cool, dry place.
• Shelf Life Information: Typically 12 months from the date of manufacture when stored correctly.
• Temperature Considerations: Allow adhesive to reach room temperature before opening to prevent condensation.

Certifications

• Approved to MIL-A-46050C Type II Class 3 (existing designs)
