Product Name
Permabond 170 High Viscosity Liquid Methyl Cyanoacrylate Adhesive
Brief Description
Permabond 170 is a high-viscosity, fast-curing methyl cyanoacrylate adhesive designed for creating strong bonds on a variety of materials, particularly metals and sensitive plastics. It cures rapidly at room temperature and is compliant with MIL-SPEC MIL-A-46050C Type I, Class 3, making it suitable for demanding industrial and specialized applications.
Popular Applications & Uses
- Bonding metals such as steel, aluminum, brass, and stainless steel.- Bonding sensitive plastics like polycarbonate, ABS, and Styrofoam.- Adhering various types of rubbers.- General product assembly and industrial manufacturing processes.- Applications requiring gap-filling due to its high viscosity.- Repairing cracks, joints, and seams in building materials.- Woodworking for bonding porous materials and filling voids or cracks.
Industries that Commonly Use It
- Aerospace/Defense- Automotive Service/Repair- General Manufacturing- Metal Fabrication- Plastic Fabrication- Construction/ Building Services- Furniture (for woodworking applications)- Industrial Supply- Chemical Industry
Special and Unique Features
- High-viscosity formula allows for precise application and excellent gap-filling capability up to 0.38 mm (0.015 in).- MIL-SPEC compliant (MIL-A-46050C Type I, Class 3), ensuring suitability for military and aerospace applications.- Less aggressive to sensitive plastics such as polycarbonate, ABS, and Styrofoam, which helps reduce stress cracking.- Delivers exceptional bond strength, particularly on metal surfaces.- Fast cure time, achieving handling strength in approximately 15 seconds on various substrates.- Provides high shear and impact strength for durable and long-lasting bonds.- Single-part, no mixing required, 100% solids, and solvent-free for ease of use and environmental benefits.- Exhibits resistance to temperature fluctuations, moisture, and various chemicals.

Comparison Note
Permabond 170, as a methyl cyanoacrylate, offers superior performance on metal surfaces and enhanced heat resistance compared to many ethyl cyanoacrylate formulations. Its high viscosity makes it particularly effective for gap-filling applications and use on porous or vertical surfaces, where lower viscosity adhesives might run or be less effective. Furthermore, it is specifically formulated to be less aggressive to sensitive plastics, minimizing the risk of stress cracking often associated with standard cyanoacrylates.
