Description

The 3M™ Urethane Seam Sealer is a high-solids, single-component moisture-curing sealant designed for automotive and RV applications. It adheres well to primed metal, painted surfaces, and bare metal, providing long-lasting support to seams without shrinking, cracking, or producing unpleasant odors. This paste-form sealer is available in white and is paintable after 30-45 minutes, making it suitable for both interior and exterior seams to help prevent water, dust, and air intrusion, thus aiding in corrosion resistance.
