Permabond 941 cyanoacrylate adhesives Instant Adhesive-Low Odor, Non-Frosting Non-Fogging Clear Thin Wicking

Product Name

Permabond 941 cyanoacrylate adhesives Instant Adhesive-Low Odor, Non-Frosting Non-Fogging Clear Thin Wicking

Brief Description

Permabond 941 is a one-part, low odor, non-fogging, non-frosting alkoxyethyl cyanoacrylate adhesive. It cures rapidly at ambient temperatures by reacting with minute traces of moisture on the surface of the material being bonded. This clear, thin, wicking instant adhesive is formulated to bond flexible or rigid surfaces made from a wide range of plastics, rubbers, or metals, and is particularly valued for applications where aesthetic appearance and worker comfort are critical.

Popular Applications & Uses

- Product assembly and manufacturing- Wire tacking and strain relief in electronics- Bonding PVC to PCB (Printed Circuit Boards)- General bonding and repair tasks- Infiltrating granular 3D printed models to improve appearance and strength, where low odor and low blooming are essential- Applications requiring good wicking characteristics for penetration into close-fitting parts- Bonding close-fitting components where a thin adhesive is required

Industries that Commonly Use It

- General Manufacturing- LED/Electronics- Plastic Fabrication- Metal Fabrication- Cabinet & Woodworking- Sign & Display, especially for clear plastics where non-frosting is crucial- Automotive Service/Repair and Transportation/Specialty Vehicle for component assembly- Chemical Industry (as a chemical product)- Distributers & Resellers (as a product sold through distribution channels)

Special and Unique Features

- Low odor for improved worker comfort, making it suitable for areas with poor ventilation- Non-frosting (low bloom) to ensure a good aesthetic appearance by eliminating unsightly white residue adjacent to bond lines- Non-fogging, which eliminates unsightly fogging, common with other cyanoacrylate adhesives on hot and humid days, improving part appearance and production rates- Ease of use, requiring no mixing or heat cure- 100% reactive with no solvents, contributing to a safer work environment- Considered work environment-friendly and pictogram-free in some regions

Key Properties

- Chemical composition: Alkoxyethyl cyanoacrylate- Appearance: Colorless (clear)- Viscosity @ 25°C: 10-20 mPa.s (cP), indicating a thin, wicking consistency- Specific gravity: 1.1- Maximum gap fill: 0.08 mm (0.003 in)- Fixture / handling time: Varies by substrate, typically 2-5 seconds for rubber, 10-15 seconds for steel, PVC, ABS, and phenolic resin- Full strength: Achieved within 24 hours- Service temperature range: -55°C to +80°C (-65°F to 180°F)- Cure method: Moisture cure

Surface Compatibility

- Bonds most materials, including a wide range of porous and non-porous surfaces- Plastics: Such as PVC, ABS, phenolic resin, acrylic, and polycarbonate- Rubbers: Including neoprene and NBR- Metals: Such as steel, aluminum, zinc, copper, and its alloys- Wood- Suitable for both rigid and flexible materials- Not recommended for continuous contact with strong oxidizing materials and polar solvents

Known backups / known substitutes

- Permabond 940: A similar low-odor, non-fogging, non-blooming cyanoacrylate with a lower viscosity- Permabond 943: A similar low-odor, non-fogging, non-blooming cyanoacrylate with a higher viscosity and greater gap-filling ability- Permabond 947: The highest viscosity in Permabond's 94X range, also with low odor and bloom- Other low odor, low bloom cyanoacrylate adhesives from manufacturers like Infinity Bond or Turbo Fuse

Comparison Note

Permabond 941 is a key product within Permabond's 94X series of alkoxyethyl cyanoacrylate adhesives, which are specifically formulated for their low odor, non-frosting, and non-fogging characteristics. It stands out for its thin, wicking viscosity (10-20 cP) and precise gap-filling capability (0.08 mm), making it ideal for applications requiring a clean, aesthetically pleasing bond on close-fitting parts, while also enhancing worker comfort due to its reduced odor.
