LOCTITE 407 is a transparent, colorless to straw-colored, low-viscosity cyanoacrylate adhesive. This one-part formulation requires no mixing, simplifying application processes. It delivers robust bonding across diverse industrial substrates, including rubbers, plastics, and metals. Furthermore, LOCTITE 407 is specifically engineered for applications demanding superior heat resistance.
General Information of LOCTITE 407
LOCTITE 407 utilizes advanced cyanoacrylate technology, based on an ethyl cyanoacrylate chemical type. This adhesive cures rapidly upon exposure to atmospheric moisture, initiating a polymerization process. Consequently, it achieves functional strength in a relatively short timeframe. Full chemical and solvent resistance develops over approximately 24 hours. This single-component system streamlines manufacturing operations, eliminating the need for complex mixing equipment.
The curing speed of LOCTITE 407 varies depending on the substrate material and bondline gap. Thinner bond lines promote faster cure rates. However, larger gaps may necessitate the use of an activator to accelerate curing. Users should conduct testing when employing activators, as they can influence ultimate bond strength. This product is not suitable for pure oxygen systems or as a sealant for strong oxidizing materials.
Key Features & Technical Benefits
- Rapid Fixture Time: Achieves handling strength quickly on various substrates. This accelerates assembly processes and improves production efficiency.
- High Heat Resistance: Maintains bond integrity under elevated temperatures. Consequently, it ensures reliability in demanding thermal environments.
- Versatile Substrate Bonding: Effectively bonds rubbers, plastics, and metals. This reduces the need for multiple specialized adhesives.
- One-Part Formulation: Requires no mixing or complex preparation. This simplifies application and minimizes material waste.
Typical Industrial Applications
This formulation is engineered for the following applications:
- General-purpose industrial bonding requiring heat resistance
- Assembly of components made from rubber, plastic, and metal
- Applications where fast curing and high strength are critical
