Loctite 406 – Instant Adhesive for Plastics and Rubber

Loctite 406 is a high-performance, low-viscosity cyanoacrylate instant adhesive designed for rapid bonding of plastics, rubber, elastomers, and other close-fitting materials. Engineered for industrial use, it provides exceptionally fast fixture times and develops strong, durable bonds within seconds, helping improve assembly efficiency and reduce production downtime.

This adhesive is particularly effective on difficult-to-bond materials such as EPDM, nitrile rubber, neoprene, and many common plastics. When used with a suitable primer, it can also achieve excellent adhesion on low surface energy plastics such as polyethylene (PE) and polypropylene (PP).

Loctite 406 features a thin, low-viscosity formula that easily penetrates tight-fitting joints through capillary action, ensuring precise application and consistent bond strength. It is widely used in electronics, automotive, medical device manufacturing, consumer products, and general industrial assembly where clean, fast, and reliable bonding is required.
