Product Name
Permabond 943 cyanoacrylate Instant Adhesive-Low Odor, Non-Frosting Non-Fogging Clear Thin Wicking
Brief Description
Permabond 943 is a low odor, non-fogging, non-frosting alkoxyethyl cyanoacrylate adhesive. It is a single-component, 100% reactive, and solvent-free adhesive that polymerizes rapidly when pressed into a thin film between parts, initiated by moisture on the surface.
Popular Applications & Uses
- Bonding a variety of porous and non-porous surfaces- Bonding rigid or flexible materials- Ideal for high-speed production lines- Applications where low odor and low bloom (fogging/frosting) are desired- Ideal for dark plastics where good aesthetic appearance is needed- Wicking and precision bonding- Product assembly and manufacturing- General bonding and repair
Industries that Commonly Use It
- General Manufacturing: For high-speed production lines and product assembly where efficient and clean bonding is required.- Plastic Fabrication: Especially for dark plastics where aesthetic appearance is critical due to its non-fogging/non-frosting properties.- Metal Fabrication: For bonding various metal components.- LED/Electronics: For precision assembly where clean bond lines and low odor are important for sensitive components and worker comfort.- Medical Device/ Prosthetics: For assembly of components requiring clean, aesthetic bonds and improved worker comfort during manufacturing.- Automotive Service/Repair: For bonding interior or small components where aesthetics and low odor are beneficial.- Sign & Display: For assembling signs and displays where a clear, non-fogging bond is essential for visual quality.- Furniture: For assembly applications where clean bonds and a low odor environment are desired.- Artist, Artisan: For detailed and precision work on various materials where aesthetic finish and worker comfort are prioritized.
Special and Unique Features
- Low odor for improved worker comfort- Non-frosting, ensuring good aesthetic appearance- Non-fogging, eliminating unsightly fogging adjacent to bondlines, improving production rate and appearance- Ease of use – no mixing or heat cure required- Bonds most materials effectively- 100% reactive, containing no solvents- Clear appearance- Thin wicking viscosity for penetrating tight joints
Key Properties
- Chemical Composition: Alkoxyethyl cyanoacrylate- Cure Mechanism: Rapid polymerization initiated by moisture on surfaces, curing in seconds at ambient temperatures- Viscosity: Thin, low viscosity, wicking- Color: Clear- Maximum Gap Fill: 0.15 mm (0.006 in), 0.1 – 0.2 mm- Operating Temperature Range: -30°C to +85°C (-22°F to +185°F)- Brief High-Temperature Resistance: Can withstand higher temperatures for short periods (e.g., paint baking, wave soldering)- Minimum Temperature: -55°C (-65°F)- Shear Strength (e.g., Steel): 16-20 N/mm² (2300-2900 psi)- Impact Strength: 3-5 kJ/m² (1.4-2.4 ft-lb/in²)- Hardness: 85 Shore D- Dielectric Strength: 25 kV/mm- Dielectric Constant @1MHz: 3- Shelf Life: One year when refrigerated (2 to 7°C / 35 to 45°F)
Surface Compatibility
- Bonds most materials, including plastics, rubbers, and metals- Metals: Aluminum, copper, and its alloys (benefit from light abrasion to remove oxide layer)- Porous/Difficult Surfaces: Use of a Permabond activator is recommended- Low Surface Energy Plastics (e.g., polypropylene, polyethylene, PTFE, silicone): Prime first with Permabond Polyolefin Primer (POP)
Known backups / known substitutes
- Permabond 940: A similar low odor, non-fogging, non-frosting alkoxyethyl cyanoacrylate with thin viscosity.- BSI Super-Gold+™ Odorless Foam-Safe CA: An odorless, foam-safe cyanoacrylate that does not fog clear plastic and glass.- Starbond Odorless "Infiltrant" Thin Super Glue: A fumeless, hypoallergenic, ultra-thin viscosity CA glue.- Other low odor, low bloom cyanoacrylate super glues from various manufacturers (e.g., Infinity Bond).
Comparison Note
Permabond 943 distinguishes itself from traditional cyanoacrylate adhesives through its advanced alkoxyethyl formulation. This chemistry inherently provides low odor, non-frosting, and non-fogging characteristics, directly addressing common aesthetic and comfort drawbacks associated with standard ethyl cyanoacrylates. These features make it particularly advantageous for applications requiring superior visual quality, especially on dark or clear substrates, and in environments where improved worker comfort and reduced fumes are critical.
