LORD 406/19 Fast Setting (4-6 Minute) Temperature Resistant, Non-Sag acrylic adhesives

Product Name

LORD 406/19 Fast Setting (4-6 Minute) Temperature Resistant, Non-Sag acrylic adhesives

Brief Description

LORD 406/19 is a high-performance, two-component acrylic adhesive system designed for structural bonding. It is formulated to replace traditional mechanical fastening methods such as welding, brazing, and riveting. This adhesive system provides rapid fixture times, excellent environmental resistance, and strong, flexible bonds, performing particularly well in low-temperature environments and applications subject to high impact or high peel loads.

Popular Applications & Uses

- LED channel letters- Aluminum and composite panel bonding- Sign cabinet assembly- Architectural and display applications- Bonding unprepared metals and engineered thermoplastics- Exterior vehicle components like door panels and framework- Joining and sealing window mounts in construction- Bonding magnets in electrical motors and speakers- General structural bonding where high impact and peel strength are required

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Construction/ Building Services- Fabrication- General Manufacturing- LED/Electronics- Marine- Metal Fabrication- Plastic Fabrication- Sign & Display- Transportation/ Specialty Vehicle

Special and Unique Features

- Replaces welding, brazing, riveting, and other mechanical fastening methods- Performs particularly well in low-temperature environments- Provides highest impact and peel strengths available in a room temperature curing adhesive- Non-Sag formula remains in position on vertical or overhead surfaces, allowing for greater process flexibility- UL 746C certified when mixed with LORD Accelerator 19- Versatile bonding to a wide range of unprepared metals and engineered thermoplastics with minimal substrate preparation
