3M 7000120463 Heavy-bodied Seam Sealer 200 Ml Cartridge

Product Description

The 3M 7000120463 is a two-part epoxy seam sealer designed for use on vertical and horizontal seams in automotive and industrial body repair applications. Packaged in a 200 mL cartridge, it delivers a non-sagging, non-flowing consistency that holds position on vertical surfaces without running. The material is workable for approximately 10 minutes after mixing, then becomes paintable within 30 minutes, allowing repair workflows to continue without extended waiting. It resists shrinkage and cracking across a wide temperature range, maintaining a flexible seal over the long term. Body technicians and collision repair professionals are the primary installers.

This seam sealer is formulated to duplicate OEM seam beads on vehicle body panels. It is suited for both horizontal lap seams and vertical butt joints in collision repair, frame repair, and body panel replacement scenarios. The fast setup time is particularly useful in production shop environments where technician productivity is a priority. Its toolable consistency allows the bead to be shaped or smoothed to match factory seam profiles before it cures.

Installation Notes

Installation is typically performed by collision repair technicians or body shop professionals. Use a dual-component cartridge dispensing gun compatible with 200 mL two-part cartridges to ensure proper mixing ratio. Clean and dry all surfaces before applying sealer, and remove any loose rust, old sealer, or contaminants. Allow full cure before exposing the seam to moisture or thermal cycling.
