Features
■ Cures to a strong durable bond in 24-48 hours at 75°F (24°C).
■ Paste viscosity which allows the use of Scotch-Weld EC-1648 B/A on vertical or overhead surfaces with little or no tendency to flow.
■ Good adhesion to steel.
■ Good retention of strength after aging in many environments.

Product Application Proper adhesive application is as important as proper bond design and adhesive choice to obtain maximum joint properties. Improper adhesive application techniques can result in partial or complete failure of an assembly. Scotch-Weld EC-1648 B/A performance data reported in later section (Test Results) was developed using the following suggested procedures. Variations from these procedures should be fully evaluated to insure bond properties sufficient to meet the requirements of your particular assembly. Surface Preparation A thoroughly cleaned, dry, grease-free surface is essential for maximum performance. Cleaning methods which will produce a break-free water film on metal surfaces are generally satisfactory.
