LOCTITE 406 – Instant Adhesive for Plastics & Rubber

LOCTITE 406 is a high-performance, low-viscosity instant adhesive designed for the rapid bonding of plastics, rubber, and elastomeric materials. This industrial-grade cyanoacrylate adhesive offers extremely fast fixture times, making it ideal for high-speed manufacturing, maintenance, repair, and assembly applications. For difficult-to-bond plastics such as polyethylene (PE) and polypropylene (PP), LOCTITE 406 can be used with a suitable primer to achieve improved bond strength.

Frequently Asked Questions
What is LOCTITE 406 used for?
It is primarily used for fast bonding of plastics, rubber, and elastomeric materials in industrial and manufacturing applications.
Can LOCTITE 406 bond polyethylene (PE) and polypropylene (PP)?
Yes, but these materials generally require a compatible primer to achieve optimal bond strength.
How quickly does LOCTITE 406 cure?
Fixture time is typically only a few seconds, depending on the substrates and environmental conditions.
Is LOCTITE 406 suitable for metal bonding?
Yes. It can bond metals, particularly in close-fitting assemblies, although it is optimized for plastics and rubber.
Can LOCTITE 406 fill large gaps?
No. It is a low-viscosity adhesive intended for close-fitting parts and is not recommended for large-gap filling.
