Product Description
Permabond® 940 Cyanoacrylate is a low-odor, non-frosting, alkoxyethyl-based cyanoacrylate adhesive engineered to improve worker comfort and maintain a clean aesthetic. This 100% reactive, single-component adhesive cures rapidly at room temperature, eliminating the unsightly white fogging (blooming) that commonly occurs with standard cyanoacrylates on hot and humid days. It is surface-insensitive and rapidly bonds a wide range of materials, including plastics, metals, elastomers, and acidic surfaces.
Key features
- Low odor formulation: Alkoxyethyl chemistry significantly reduces irritating fumes, improving worker comfort during application.
- Non-frosting/Non-fogging: Eliminates the white residue (blooming) adjacent to the bondline, ensuring a flawless aesthetic appearance on finished parts.
- Fast room-temperature cure: Provides rapid fixture times (e.g., 2-5 seconds on Neoprene/NBR and 10-15 seconds on steel), eliminating the need for mixing or heat.
Applications / Suitable for
- Applications requiring a clean, fog-free aesthetic finish
- Environments where low-odor adhesives are necessary for worker comfort
- Rapid bonding of plastics, metals, and elastomers
