3M 8329 Controlled-Flow Seam Sealer (200 mL)

3M Control-Flow Seam Sealer uses two-part urethane technology to provide a tough flexible material for the sealing of joints on primed or painted substrates such as steel or aluminum enclosures. 3M Control-Flow Seam Sealer works particularly well in areas where a flowable self-leveling type seam sealer is required, it is designed to flow one to two inches then begins to cure preventing further flow out of the material, this feature allows the user to control application preventing excessive waste while maintaining a uniform film thickness even on surfaces that are not level.

Features:

• Two-part urethane technology offers tough, flexible performance
• Good adhesion properties to primer or painted surfaces
• Controlled application prevents excessive waste
• Sealer flows 1 to 2 in on non-level surfaces
• Cured sealer will not shrink or crack
