Permabond 947 Instant Adhesive-Low Odor, Non-Frosting Non-Fogging Thick Gap Filling

Product Name

Permabond 947 Instant Adhesive-Low Odor, Non-Frosting Non-Fogging Thick Gap Filling

Brief Description

Permabond 947 is a low-odor, non-fogging, non-frosting alkoxyethyl cyanoacrylate adhesive. It is a single-component, 100% reactive, solvent-free instant adhesive designed for improved worker comfort and superior aesthetic results. This adhesive cures rapidly at room temperature by reacting with surface moisture and is capable of bonding a wide variety of materials.

Popular Applications & Uses

- Bonding smaller details and components- General assembly of various materials where a fast, strong bond is required- Applications where aesthetic appearance is critical, as it eliminates unsightly fogging and frosting common with other cyanoacrylates- Wire tacking, lighting, and electric motor tacking and bonding- Bonding substrates that may be subject to fogging adjacent to bondlines

Industries that Commonly Use It

- General Manufacturing- Metal Fabrication- Plastic Fabrication- Automotive Service/Repair- LED/Electronics- Medical Device/Prosthetics- Sign & Display- Furniture- Cabinet & Woodworking

Special and Unique Features

- **Low Odor:** Significantly improves worker comfort in production environments- **Non-Frosting:** Prevents the white, powdery residue (bloom) often seen on bond lines, ensuring a clean, professional finish and good aesthetic appearance- **Non-Fogging:** Eliminates unsightly fogging adjacent to bondlines, which is common with other cyanoacrylate adhesives on hot and humid days, improving production rates and part appearance- **Ease of Use:** Requires no mixing or heat cure, and is ready to use directly from the bottle- **100% Reactive:** Contains no solvents

Key Properties

- **Chemical Composition:** Alkoxyethyl Cyanoacrylate- **Appearance:** Colorless liquid- **Viscosity @ 25°C:** 900 - 1,500 mPa.s (cP)- **Maximum Gap Fill:** 0.25 mm (0.01 in)- **Typical Fixture Times:** - Neoprene / NBR: 2-5 seconds - PVC, Phenolic Resin, ABS, Aluminum: 10-15 seconds - Steel: 20-30 seconds - Zinc: 30-40 seconds- **Full Strength:** 24 Hours- **Temperature Range:** -55°C to 120°C (briefly up to 150°C)- **Hardness, Shore D:** 85- **Shear Strength (e.g., Steel):** 16.0 - 20.0 MPa (2320 - 2900 psi)

Surface Compatibility

- **Metals:** Steel, Aluminum, Zinc, Copper, Metal surface facia- **Plastics:** PVC, Phenolic, ABS, Black or dark plastic, Polyolefin (with primer)- **Rubbers:** Neoprene, NBR, Butyl Rubber- **Other:** Composites, Carbon Fibre, Most materials- **Surface Preparation:** Surfaces should be clean, dry, and grease-free. Degreasing with acetone or isopropanol is recommended. Light abrasion may benefit some metals

Known backups / known substitutes

- **Permabond 940, 941, 943:** Similar Permabond alkoxyethyl cyanoacrylate adhesives with different viscosities.- **Permabond C Surface Activator (CSA) or Permabond QFS 16:** Can be used to overcome slower cure speeds on larger gaps or acidic surfaces.- **Other Permabond Cyanoacrylates:** Depending on specific requirements, other grades like Permabond 105 (for difficult plastics & rubbers), Permabond 2050 (thick gel, flexible), Permabond 731/735/737 (toughened for impact/peel strength) could be considered for different properties.

Comparison Note

Permabond 947 stands out from traditional cyanoacrylate adhesives due to its alkoxyethyl formulation, which provides significantly reduced odor, and eliminates the common issues of frosting (white residue) and fogging (haze) around bond lines. This makes it particularly suitable for applications where worker comfort and the aesthetic appearance of the bonded parts are paramount.
