Description

3M - Urethane Seam Sealer - 310 ml

3M Urethane Seam Sealer is a high solids seam sealer ideal for sealing automotive and RV seams and joints. It adheres well to bare metal, primed metal and painted surfaces, and if desired can be smoothed to a featheredge and/or brushed. Tack free and paintable after 30-45 minutes, this urethane formula is permanently flexible and offers superior performance to solvent-based sealers.

Features:
  • Versatile Application: A high-quality, single-component formula adheres well to bare metal, primed metal, and painted surfaces.
  • Moisture Curing Properties: Provides excellent performance in high-heat and humid environments.
  • Permanent Elasticity: A non-shrinking, non-cracking, low-to-no odor formula remains flexible and offers superior results to solvent-based sealers.
  • Paintable In Minutes: Work faster using a sealer that is paintable in just 30-45 minutes.
  • Gap Filling Consistency: Thick consistency enables the filling of large voids while helping to prevent corrosion.
