Loctite 404 – High-Performance Cyanoacrylate Instant Adhesive for Plastics, Rubber, Metals and Porous Materials

✅ Loctite 404 is a high-performance ethyl cyanoacrylate instant adhesive designed for rapid bonding of a wide variety of materials including plastics, rubber, metals, wood, leather, paper, ceramics, and porous substrates. Its fast curing speed significantly reduces assembly time while improving productivity in manufacturing and industrial maintenance.

✅ The adhesive cures rapidly by reacting with trace moisture on the bonding surfaces, producing a strong and durable bond within seconds. Its low-to-medium viscosity allows excellent penetration into close-fitting joints while providing clean and consistent adhesive application.

✅ Loctite 404 is particularly suitable for bonding porous and slightly acidic materials such as wood, paper, leather, and fabric, while also delivering excellent performance on engineering plastics and metallic components. It is an ideal solution for applications requiring fast fixture times and dependable bond strength.

✅ The adhesive bonds effectively to ABS, PVC, polycarbonate, NBR rubber, EPDM rubber, stainless steel, aluminum, brass, wood, leather, and ceramic materials. For low surface energy plastics such as polyethylene (PE), polypropylene (PP), and PTFE, the use of a suitable surface primer is recommended to achieve maximum bond strength.

✅ After full curing, Loctite 404 provides good resistance to moisture, light vibration, and many common industrial chemicals. Its reliable bonding performance helps improve product durability while reducing maintenance and repair time.

✅ Manufactured by Henkel under the globally recognized Loctite brand, Loctite 404 is widely used in electronics, precision engineering, plastics manufacturing, automotive production, medical devices, woodworking, crafts, and industrial maintenance applications around the world.
