Loctite 1057674 Acrylic Structural Adhesive 1000 Ml

Product Description

The LOCTITE 1057674 is a Series 331 acrylic structural adhesive packaged in a 1000 mL bottle. It bonds metal substrates and is formulated for high-temperature-resistant applications where a durable, load-bearing joint is required. The adhesive has a working time of 0.33 minutes and a fixture time of 20 minutes, making it suited for production environments where fast handling strength is a priority. Full cure is reached at 24 hours. The cured adhesive is off-white in color and delivers a shear strength of 3100 psi. This product is installed by maintenance technicians, industrial assemblers, and trade professionals working with metal fabrication or mechanical assemblies.

The LOCTITE 1057674 Series 331 acrylic adhesive is used in industrial and commercial settings where metal-to-metal bonding must withstand elevated temperatures and mechanical stress. Typical applications include metal panel assembly, structural bonding of brackets and housings, and repair applications in HVAC, plumbing, and mechanical service environments. The large 1000 mL bottle format is suited for bench or production-line use where volume application is needed.

Installation Notes

Surface preparation is critical — clean and degrease all metal surfaces before application to achieve rated bond strength. Follow the manufacturer application instructions for mix ratio and dispensing method appropriate to the Series 331 system. Ensure adequate ventilation during use and wear appropriate PPE including gloves and eye protection. Allow full 24-hour cure before applying load to the bonded joint.
