LOCTITE 407 is a high-performance, one-part cyanoacrylate adhesive engineered for robust industrial bonding. It delivers exceptional strength across diverse substrates, including rubbers, plastics, and metals. This formulation ensures rapid fixture times and maintains reliable performance even in demanding, heat-resistant environments.
General Information of LOCTITE 407
LOCTITE 407 is based on advanced cyanoacrylate technology. Specifically, it utilizes an ethyl cyanoacrylate chemical type. This transparent, colorless to straw-colored liquid requires no mixing, which significantly simplifies application processes. Consequently, it streamlines manufacturing workflows.
The adhesive’s curing mechanism initiates upon exposure to atmospheric moisture. While functional strength develops quickly, full chemical and solvent resistance requires at least 24 hours. Cure speed varies depending on the substrate and bond gap. Thin bond lines promote faster curing.
Furthermore, LOCTITE 407 is a general-purpose adhesive. It is particularly noted for its excellent heat resistance properties. This characteristic makes it suitable for applications where elevated temperatures are a concern, ensuring long-term bond integrity.
Key Features & Technical Benefits
- Cyanoacrylate Technology: Provides rapid, reliable bonding for increased production efficiency.
