3M 7100004037 Rigid Pillar Foam 200 Ml Cartridge

Product Description

The 3M 7100004037 is a two-part urethane rigid pillar foam supplied in a 200 mL cartridge. It foams in place to fill posts, pillars, and automotive body cavities, expanding to approximately 10 times its original volume. The expanded foam adds structural strength and eliminates wind noise in treated cavities. Foam time is 1 minute, work time is 5 minutes, and full cure is reached at 1 hour. This product is designed as a direct replacement for OEM rigid foams and is used by auto body technicians and structural repair specialists.

This urethane foam is intended for automotive body cavity applications including door pillars, A-pillars, B-pillars, and similar structural voids where OEM foam has been removed or damaged. The low-viscosity liquid flows into cavities before expanding, ensuring thorough fill even in irregular or hard-to-reach spaces. It is used in collision repair and restoration work where restoring original rigidity and noise damping characteristics is required. Use with the 3M 08117 applicator for proper two-part metering and mixing.

Installation Notes

Installation is performed by auto body technicians following applicable collision repair procedures. Ensure the cavity is clean and free of loose debris before injecting foam.
