Loctite 401 – General Purpose Cyanoacrylate Instant Adhesive for Plastics, Rubber, Metals and Wood

✅ Loctite 401 is a general-purpose ethyl cyanoacrylate instant adhesive designed for rapid bonding of a wide variety of materials including plastics, rubber, metals, wood, paper, leather, ceramics, and composite materials. Its extremely fast curing speed helps reduce assembly time, improve manufacturing efficiency, and lower maintenance costs across industrial applications.

✅ The adhesive cures by reacting with the natural moisture present on the bonding surfaces, creating a strong and durable bond without the need for heat or additional curing equipment. This makes Loctite 401 an excellent solution for both automated production lines and manual assembly processes.

✅ With its medium-viscosity formulation, Loctite 401 provides excellent application control, minimizing adhesive runoff while producing a consistent bond line. It is particularly suitable for close-fitting parts where precise adhesive placement is required.

✅ Loctite 401 bonds effectively to ABS, PVC, polycarbonate, NBR rubber, EPDM rubber, stainless steel, aluminum, brass, wood, paper, leather, ceramics, and composite materials. For low surface energy plastics such as polyethylene (PE), polypropylene (PP), and PTFE, the use of a compatible primer is recommended to achieve maximum bonding performance.

✅ Once fully cured, the adhesive provides good resistance to moisture, light vibration, and many common industrial chemicals. Its durable bond improves product reliability, extends service life, and reduces the likelihood of joint failure during operation.

✅ Manufactured by Henkel under the globally recognized Loctite brand, Loctite 401 is widely used in electronics, precision engineering, plastics manufacturing, automotive production, medical device assembly, furniture manufacturing, electrical equipment production, and industrial maintenance.
